Chaste Hero

"Schlock: Too bad about that Celibacy thing. Reverend: My order doesn't do celibacy. We take an oath of chastity. Schlock: What's the difference? Reverend: When you are alone in an elevator with a beautiful woman you barely know... (sigh) There isn't a difference. Schlock: You religious people have too many words for "responsible behavior.""

- Schlock Mercenary

The Chaste Hero is a character, usually a teenage male, who is completely oblivious to embarrassment of women and to romance in general. Flirtation is dismissed because he honestly doesn't get it, and pushy insistence from the Bottle Fairy or Cool Big Sis is waved off with angry annoyance. This can be a paradoxically commentary on the character's lack of "maturity," but strangely, this rule does not necessarily mean the younger male characters of the cast won't react to attractive people.

The female version is usually tomboyish and a slightly dense jock slowly being cultivated into a budding Bottle Fairy.

One bonus from this is immunity from awkwardly placed falls, gestures, and hands that plague a lot of characters—and, if it happens, no apologies for it, something the average male would be expected to do. Similarly, it pretty much allows him to interact and talk to any woman in the series, something another friend may be incapable of doing. This is especially useful if the writers are trying to avoid Shipping, simply don't want it to seem the guy is taking advantage of having many admirers, or want to set up a romantic admirer who just doesn't get that he just doesn't get it. Quite a few times, in order to allow the Chaste Hero to string along a romantic admirer without seeming like a jerk, they might say something that sounds like a love confession, only for them to continue on by saying that they also love everyone.

The Chaste Hero is very common in "juvenile" fiction, especially in the past. It gets rather annoying when he sometimes wonders why his close female friend is so nice to him.

Contrast with the Celibate Hero and Asexuality, tropes dealing with non-clueless characters that either actively shun romance or simply have no interest in it.

Compare Innocent Fanservice Girl and Ms. Fanservice. To double on the appeal, Chaste Heroes often double as Chick Magnets. See also Clueless Chick Magnet. If a seeming Chaste Hero turns out to be far more interested in sex than they appear, you've just met the Covert Pervert. Not to be confused with a Chased Hero.

Anime and Manga
"Hina: Do you have feelings for Ayumu? Hayate: I-I don't know... Hina: ...how about me? Hayate: Well, th-that's-- Hina: How about my sister? Hayate: (instantly) No."
 * Negi Springfield from Mahou Sensei Negima. Since he is only ten years old.
 * Kouji Kabuto from Mazinger Z. He was not so bad in the original manga, but in the anime series, he doesn't get when a woman is interested in him, especially if that woman is Sayaka (or Maria from UFO Robo Grendizer). If they tried to flirt, often he replied by teasing them. Given that the two of them were hot-tempered Tsunderes, you can tell how well it ended for him. Tetsuya Tsurugi from Great Mazinger was even worse, since he was so obsessively focused on fulfilling his mission (due to he thought piloting Great Mazinger was everything what he had) that if Jun tried to seduce him he didn't get it or taunted her or both (and since she had no patience for stupidty, they ended up fighting).
 * Judai of Yu-Gi-Oh! GX, though this is not seen much only because there's only one other major character that's a girl. (Well, technically two, but Rei's crush on him is a precocious type, as she's only 10 and gained admittance to Duel Academy via early promotion.) Of course, he's just as oblivious to the feelings of members of the same sex, anyway.
 * Yuma in Yu-Gi-Oh Ze Xal shows that he is a Chaste Hero in a pretty hilarious way. In Episode 9, he repeatedly interrupts a girl trying to confess to him during a duel, only to defeat her. Even Astral notices afterwards: "Observation #11: It seems Yuma still doesn't understand the thoughts of females." Ultimately subverted, however, as he is the first protagonist to truly return another's feelings, doing so with Kotori in the final season.
 * Makoto Kousaka from Genshiken partially fits this trope; he has a girlfriend, and is hardly chaste, but is otherwise a good embodiment, oblivious to flirtation even, most of the time, his girlfriend's, as well as embarrassment.
 * Then again, given his demeanor no one can guess what he does during his time alone with Saki.
 * It's made pretty clear that he isn't a virgin and that he has slept with Saki numerous times. He does partially fit the trope in terms of his personality though.
 * Shungo Ninomiya, the titular character from Goshuushou-sama Ninomiya-kun ("My condolences, Mr. Ninomiya"), is a martial artist with a Bottle Fairy big sis who knows kung fu. Because of his being more or less a Chaste Hero who also knows his way around a fight, and because his being Chaste makes him semi-immune to her out-of-control magical sex appeal, she saddles him with the task of trying to "heal" a young succubus's fear of men using shock therapy... . He's also pretty much the only one unaware that his rich admirer-turned-maid friend is head over heels for him.
 * Sagara Sousuke from Full Metal Panic!!, who doesn't recognize romance when it walks up to him and slaps him in the head with a Paper Fan of Doom. Repeatedly. He thinks that "kissing" is a synonym for "CPR", tries to "pick up women" by ambushing random women on the street, putting them in cages and holding them captive at gunpoint, and wonders what high schoolers would need condoms for, since it's unlikely they'll ever need emergency water containers.
 * He doesn't even understand or even remotely attempt to understand the "love" part of a "love letter." In fact, he thinks it is a death threat and the pink paper, perfume and heart signature means it's reverse psychology; obviously professional work.
 * Though most of the death threat part was because the love letter was heavily damaged. Sousuke figured that someone put something potentially dangerous in his locker, and blew it up with high-yield explosives. Since the letter was tattered, he filled in the blanks with his twisted logic. However, without a doubt, he would've misunderstood the letter even if the letter was undamaged.
 * To be fair to Sousuke, the parts that were left were "I watch you from afar," "coward," "heart stop beating," "rest in peace," and "wait behind the gym after school."
 * Not to mention the fact that he completely freaks out and panics every time Tessa comes on too strong (the OVA is an excellent example of this).
 * Neon Genesis Evangelion's Rei is the resident Emotionless Girl, so she isn't the least bit fazed when she comes out of the shower and accidentally ends up with Shinji on top of her with his hand on her breast.
 * She was pretty comfortable pulling a Spirit Advisor in an even more intimate position with Shinji. Understandable since.
 * The titular character of Hayate the Combat Butler. He lives in the house with a master who has a crush on him and daily interacts with her circle of female friends who all also have crushes on him, and never notices. He also completely misinterprets all attempts to explain otherwise to him.
 * Hayate expressly states that he falls into this trope hard.
 * It's been revealed that his devotion to his ex-girlfriend from age 6 and his Failure Knight status to her, combined with her ingraining on him that only a self-sufficient male should pursue romance, has killed his libido. So it's a cross between this and Celibate Hero.
 * Strangely enough, there's no hint of this when he's staying at Hinagiku's house. He clearly has unclean thoughts of three of the members of his harem, and a negative reaction to the implication of her sister in the same position.
 * Hayate isn't exactly a Chaste Hero; he simply doesn't see his 13 years old Mistress and other girls of her age who are in love with him as a potential love interest because he considers them kids and he Definitely isn't a Lolicon. The situation changes when he is dealing with girls of his own age like Hinagiku, Ayumu or Maria.
 * Probably best exemplified when Hina tries to figure out whether he likes anyone.

"Lyle: That guy can be such an idiot sometimes..."
 * A use of the concept is found in Naruto, where the titular hero, despite his obvious crush on Sakura, completely misses Hinata's crush on him. This seems to be a matter of personality, as the loud and exuberant Naruto is annoyingly persistent in his pursuit of Sakura, while Hinata is so painfully shy she faints if he ever got within two feet of her. So while Naruto understands romance (sorta), he has no concept of shyness.
 * On the other hand, Sasuke is either a straight example of this or a Celibate Hero.
 * Pre Face Heel Turn at least. But Sasuke would be more likely this than Celibate Hero. The fact that one of his goals was to revive his clan and how he just tells every girl to get lost says much. Many fans even joke about how Sasuke doesn't know how babies are made.
 * Pre-DBZ Son Goku. He only agreed to marry Chi-Chi because he thought "marriage" was a type of food. (Their wedding night must have been an exercise in patience for Chi-Chi...)
 * He must have learned something from it, considering the kids they had. One's things for sure though: he sure didn't qualify for this trope anymore after getting married....
 * Considering the type of material Muten Roshi taught him to read with, he might not be as clueless in that department as he seems...
 * Their son, Gohan, seems to have inherited this from his father where Videl is concerned.
 * To his credit, he picked up on it a lot faster than Goku did, and by the end of the Buu Saga, the two are an item before marriage.
 * Mobile Suit Gundam 00 has Setsuna F. Seiei, who sneaks into a young princess's bedroom at night and doesn't seem to understand the implications... Then again, Setsuna pretty much has No Social Skills and is The Stoic, which doesn't exactly help his situation.
 * Plus, he himself has stated twice that he shares no romantic feeling for Marina. She was just as quick with that "No". This means he actually "graduated" to Celibate Hero, since he's now aware of what romance and sex are and just doesn't act on anything romance-related. It doesn't help that he seems to view Marina more as mix of a Cool Big Sis and a Replacement Goldfish for his Missing Mom...
 * On the other hand, he's clearly clueless about Feldt's open feelings for him in The Movie. Even though ! Example: Lyle even lampshades it.


 * Or maybe he does know... And has no idea what to do about it. He's not a sterling example of family values, considering why his Missing Mom went missing...

"But Pokémon like each other all the time. I don't get it. What's the big deal?"
 * Monkey D. Luffy from One Piece can't think of any reason why a naked woman would invite him into her bedroom and proclaims so. (It wasn't that, anyway.)
 * The latest Shrug of God Handwavium was something to the effect that it's not that he's completely oblivious to the opposite sex, it's just that he generally doesn't pay attention to stuff like that unless he's in mixed company. Or something...
 * It's probably safer and more logical not to think about it too much.
 * He's not completely clueless to it, he's fallen to Nami's Happiness Punch.
 * Usopp is a bad influence.
 * Also he is aware that Hancock is in love with him and wants to marry him, he just isn't interested. Which is pretty impressive, since Hancock is considered one of the most beautiful women alive. In fact, that's why Hancock is in love with him,  he is the only man she has ever met whom she cannot control with her beauty. Luffy also at least seems to understand the concept; during the Cidre Guild Arc, after he falls into a bathhouse where Boa is bathing (luckiest SOB in the world, many fans would say) both of them are pestered by the eponymous guild, and he tells her to stand up, as he knows how they'd react, enabling him to hit them when they're gawking at her.
 * Oda said that he didn't want to focus on romance during the series, the characters are in love with adventure.
 * Ken from Science Ninja Team Gatchaman. Justified in that he spent most of his life in training to be the leader of an elite ninja team. (His Battle of the Planets counterpart Mark, though, is a Celibate Hero; while he acknowledges and admits to his feelings for Princess, he won't act on them because of duty.)
 * Inverted in Fairy Tail, where Lucy seems to be the only person in the entire guild with any sense of modesty. Nobody seems to understand why she would be upset when they break into her house without permission, while she's bathing.
 * Gray does this mostly naked on some occasions, no less. But don't worry; he took his clothes off before he got there.
 * Let's not forget Fairy Tail mage Natsu's lovable sense of naivety in moments any normal teenage boy would be uncomfortable, or much too comfortable, in.
 * Natsu's naivety may be due to Lisanna's death, it's possible he was in love with her. Though the plot elements of that haven't been explored enough.
 * Subverted in chapter 261 when he tries to peek on the girls in the hot springs.
 * Keep in mind most of the Fairy Tail members of that generation were raised together, they're all orphans and socially awkward in some way or another. It's is probably that they don't even see nudity when its each other as anything sexual.
 * Especially Gray.
 * In Record of Lodoss War, Deedlit is in love with Parn, but he seems oblivious and/or doesn't know how to handle his emotions. Even so, she persists, and he eventually falls for her.
 * Played with in Saber Rider and the Star Sheriffs. Saber has had at least three Girls Of The Week (a circus artist, a school teacher and a female Vapor Being), but in one episode he's shown childishly embarrassed when his female teammate April Eagle puts the moves on him and attempts to kiss him after he saves her life. We don't know what's the deal with his original Japanese self, though...
 * Touma of A Certain Magical Index has flagged so many powerful women to his side that some are starting to believe he's forming some sort of resistance force. Yet Touma can't see beyond his own Blessed with Suck circumstances and doesn't pay much mind to the harem he's building.
 * Considering the amount of trouble his Unwanted Harem brings, it's rather plausible that Touma thinks of those women's attraction to him as part of his own Blessed with Suck package and decides to not make it worse by acting on it.
 * Ash Ketchum of Pokémon is either this or Asexual, though he wasn't always like this.
 * As of the latest of the anime series, the list of girls to have shown canon feelings for him include Misty, Melody, Macey, Anabel and Angie. To say nothing of the Pokemon who have developed crushes on him....
 * He's been having trouble recognizing love between Pokémon too. He assumed Grovyle had a fever when Grovyle was clearly crushing on Meganium and throughout DP, he's been clueless to it all.
 * His response to Dawn's Piplup crushing on another trainer's Marill says it all:


 * Early in Ash's journey through Unova, Ash captured a female Snivy with the incapacitating move Attract, which only affects Pokémon of the opposite gender. He actually uses the move against opponents, though its most likely because he recognizes it as an effective move when it hits. Meanwhile, Ash's obliviousness continues to shine through to the point that his understands more about love than he does.
 * He later doesn't understand that two Cottonees wish to mate, thinking that the male one just "wants a best buddy". This might just be the definitive showcasing of how his Characterization Marches On, as back in the first ever season of the show, Ash's Butterfree feel in love and wished to mate, and Ash was well aware of this fact.
 * To a lesser extent, Dawn—ironic, since she's probably the girliest of Ash's four female companions. This gives her a more "childish" feel, which is probably necessary as the last two "ten-year-old" companions seemed a lot older (in both behavior and looks).
 * James of Team Rocket could fall under this category as well, as the times he's shown to have fallen in love can be counted on one hand, and half the time he's under a spell (such as the Ghost on Maiden Peak episode.) The shippers will disagree, but you don't even want to start there...


 * Eureka from Eureka 7 is a rare female example of this at first, but she would eventually subvert it.
 * Brigadoon Marin and Melan's hero, Melan Blue, is completely clueless about romance; he doesn't even know what a kiss is. Justified in that he belongs to a race of robots that apparently don't reproduce sexually (he tells Marin that he doesn't have parents), so why would he need to know about sexuality or romance?
 * Ichika Orimura from Infinite Stratos has this trope forced upon him, since there are at least 5 girls interested in him (with them perceiving his older sister to be a 6th rival). While he may seem incredibly dense most of the time, other times when he seems to be a little too friendly with one of the girls, the other ones get really jealous and will do what they can to stop it. Whether it's smacking him with a kendo stick while he's pinned down in bed by a naked girl grappling his arm, or nearly getting his head shot off by the girls wearing their Powered Armor suits because he tried to kiss one of them.
 * Keith Goodman from Tiger and Bunny reacts to sexuality in one of two ways: stunning obliviousness or stammering embarrassment.
 * Fear from C3 is also a female example. She doesn't seem to clue in much about love.

Comic Books

 * Tintin. Unlike other examples, however, it is unclear whether this is a character trait or a side effect of the lack of female characters in the series.
 * Jughead Jones from Archie Comics. There's a reason for this, though. He hates women because
 * Another reason is that he already has a girlfriend, January McAndrews, who is from the future and works with him in the Time Police and is thus kept secret.
 * Subverted in XXXenophile Vol. 2 by Phil Foglio. A vibrator repairman visits the homes of horny women who show him vibrators only a little off and start throwing themselves at him. He repairs the hell out of their vibrators and leaves, oblivious to the fact that they're all over him. Then he visits the home of a man who's worn out his vibrator...

Film

 * Inverted in Pleasantville, with the entire cast being chaste and unaware of sexuality, except for the heroes.
 * Pirates of the Caribbean: Will Turner constantly missed his opportune moment with Elizabeth in the first film, and was so gentlemanly during their engagement that Elizabeth was practically shaking with frustration. "I'm so ready to be married...."
 * Though she wants desperately to change it, the socially awkward title character in Muriels Wedding is utterly clueless about sex and dating.
 * Steve Rogers in Captain America: The First Avenger, even after becoming Captain America. Pre-transformation, he was terribly shy and intimidated with women due to his small stature. His apprehension remains even after women are throwing themselves at him. Even as the seductive secretary was coming on to him, he was very reluctant and tried to politely brush away her advances.

Literature
""What's a virgin?" he said. "An unmarried girl," said Colon quickly "What, like my friend Reet?" said Carrot, horrified. "Well, no." said Colon. "She's not married, you know. None of Mrs. Palm's girls are married.""
 * Michael from Stranger in a Strange Land. He has no idea how love, sex, and relationships are supposed to work, because the creatures who raised him - Martians - have no genders. While many critics of this novel focus on his roughly half of it involves a sex cult and All Women Are Lustful in this book, this is not a case where A Man Is Always Eager; Michael does say "no" to female characters quite a lot, or at least tries to.
 * Lance-Constable Carrot in the Discworld novel Guards! Guards! never got The Talk, because his dwarf foster-parents think of puberty as happening in one's fifties. Amongst other things, his innocence leads to him mishearing "bawdy house" as "boarding house" and taking lodgings in Ankh-Morpork's most popular brothel without noticing anything odd, even though his letters home make it clear one of the girls is very flagrantly propositioning him. In his next appearance (Men At Arms) he meets Angua, falls in love, and it's stated he always knew the "mechanics", even if he didn't see how they applied to him, so that meant an end to conversations like this (note that Mrs. Palm is head of the "Seamstresses'" Guild):

""Oh, just talking with Loeen. I was introducing her to n-space… and darned if she didn't catch on fast." Fritz looked judicial. "Yes, she's bright... Want to know how bright?" "Well?" "So bright that she taught in El Nido's school. Her specialty was math. Multi-dimensional geometry, in fact.""
 * Robert A. Heinlein's early "juvenile" science fiction has several examples of this.
 * His Citizen of the Galaxy has the protagonist becoming friends with a woman who makes an enemy of her stepfather to help him, as well as being there for him all the time. For some reason he is mystified why she is so willing to help him. And then there's this scene earlier in the book, after the hero meets a new girl on his ship:


 * His Between Planets has the protagonist assisted by a woman who convinces her father to loan him money, despite the fact he has nothing to guarantee it. When he asks her to hold on to a ring for him (he thinks it has important secret information in it) she is startled about being given a ring and he doesn't understand why a woman would consider being given a ring something unusual. When her father finds out that the protagonist gave his daughter a ring, he questions it also, but the protagonist is still clueless about why it might be considered strange.
 * In Farmer in the Sky, Bill doesn't understand why Gretchen would get upset when she comes over to help him work and he immediately mentions they should also ask her sister to help. "Women are funny". When he is injured and she visits him in the hospital, "...[she] could hardly talk, which isn't like her".
 * In fact Heinlein Heroes are so darn clueless one wonders why Heinlein Heroines bother!
 * Early Heinlein Heroes, yes. Mid to Late Heinlein heroes, not so much.
 * Also all three of the specific examples are from books originally written and published for children in the '40s and 50's when mentioning sex could get adult books banned. One could assume that Heinlein deliberately included those passages/characters to highlight this trope.
 * All of Heinlein's earlier juveniles were done through Scribners as a publisher - and Alice Dalgleish, childrens books editor for Scribners, was so infamously puritanical about this that the other 1940s and 50s editors noticed.
 * Warrior Cats has Firestar in the first arc. Leafpool in Starlight might also count.
 * From the The Squire's Tales series by Gerald Morris, both Sir Dinadan and Beaufils. Galahad reads more as a deconstruction.
 * Doc Savage
 * Ujurak from Seeker Bears

Live Action TV

 * Benton Fraser of Due South has skirted this trope more than a few times; while he has been known to take an interest in women, he can be astonishingly naive about sexual matters, and he is perfectly capable of carrying on a conversation with a half-dressed exotic dancer without even thinking of breaking eye contact. (Of course, the fans have a theory about this...)
 * Carter in Hogan's Heroes seems absolutely clueless when it comes to women or the appeal of women, while all the other characters jump at the chance to even hang out with attractive girls. He has had one girlfriend, later his fiancee, later leaving him for a man of lower rank a year after he was captured by the Germans, but unlike the other men he only describes her in romantic terms rather than anything relating to her physical appeal.
 * Monk's title character, Adrian Monk is actually a widower, so he is presumed to have had a sex life once. But he's also saddled with plot-dependent OCD and phobias (which are implied to be so severe because of his wife's death). He's afraid of many things and disgusted by that which he isn't afraid of; so generally he does not consider himself available, nor is he generally considered worth approaching romantically by any female who happens to cross his path.
 * More to the point, Monk thinks of himself as very married, and the mere fact that his wife happens to be deceased does not make it any less so. He dates occasionally and halfheartedly, and in the end always returns to his default condition of being in love with his wife.
 * According to Monk while talking to his psychiatrist, the most physical his love life, even with Trudy, ever was is falling asleep holding Trudy's hand and waking up holding it.
 * Monk eventually came to regret not having a child with Trudy, adored a toddler after taking him in, and absolutely gushed over Molly Evans,.
 * Number Six from The Prisoner takes this trope to its logical extreme. Created as a subversion of the womanizing secret agent recently popularized by James Bond, Number Six is presented with numerous female guest characters over the course of the series, and he only shows any kind of sex drive.
 * It's worth noting that the episode with Six's  is the episode that star/creator Patrick McGoohan is, for the most part, not in (they did a brain swap episode to get around the fact that he was in Hollywood filming Ice Station Zebra at the time). McGoohan was uncomfortable performing love scenes and tended to avoid them throughout his career.
 * Sheldon from The Big Bang Theory apparently has no interest in sex, but he's also shown to be oblivious to women (and men) coming on to him.
 * Case in point.
 * Depending on which regeneration we're talking about, The Doctor comes off this way from time to time. The Eleventh Doctor is particularly bad about this (although it's more than implied in the Night and the Doctor shorts that he's getting some with River) whereas the Ninth was offended at the suggestion that he never ... danced. In the days of the classic series, Fanon insisted the Doctor was Chaste despite being a grandfather, supported by lines like the Fourth Doctor's "You're a beautiful woman, probably". In one of the Virgin New Adventures, the Seventh Doctor aknowledges the discrepency, admitting that failing to notice or completely misunderstanding sexual overtures [Celibate Hero just makes his life simpler]].

Tabletop RPG

 * GURPS Supers: Mixed Doubles. The super heroine Justice doesn't realize how attractive she is and doesn't notice most of the compliments and passes she receives from men.
 * Mutants and Masterminds. In the Freedom City setting, Tesla Atom of the Atom Family is not only fashion-model gorgeous but a walking, talking Geeky Turn On for anybody who likes smart girls. She is entirely unaware of this, and has managed to reach age 18 without having the slightest idea why most of her male peers suffer a temporary 40-point IQ drop whenever she's in line of sight.
 * In fairness her older brother is a guy who can grow 40 feet tall and her guardian is basically Race Bannon and Brock Samson after doing the fusion dance and they are traditionally overprotective sorts (and even her younger siblings are implied to get in on the act), so Tesla's also managed to reach this age without any of those desperately pining boys getting up the nerve to actually ask her for a date.

Video Games
"Lloyd: "You and I are a lot alike Sheena. I think we could be great friends!" Sheena: "Great... Friends." Lloyd: "What, you don't wanna?" Sheena: *Aside* "...Idiot!""
 * This fully describes Senel Coolidge from Tales of Legendia. There's even a point in the game where one of the female characters suddenly grabs him and pulls him into a deep, passionate kiss...twice. He, however, is completely unaffected both times.
 * He's just too fixated on STELLAAAAAAAAAAA! to notice any other girl.
 * Lloyd Irving from Tales of Symphonia is much the same way. Observe the following exchange between him and Sheena in Flanoir:

"Yukimura: "I don't understand this. Women are so complicated...""
 * Stahn plays the trope straight... and then doesn't. He's completely oblivious to romantic infatuation he suffers from/causes towards Philia or Rutee, but when Ilene mentions she's taking him on a date, he... gets pretty expressive about the whole thing.
 * Similarly Justin from Grandia. Super-hot Feena's rather overt moves on him are totally lost on him, to the point where, when she asks if he loves her, he replies, "Of course I love you! And-" goes on to name all the other people in their party, who also "love" her.
 * In the epilogue, it is made perfectly clear that at some point he got the hint.
 * Dart is like this at first with Shana in The Legend of Dragoon (not to be confused with the above show), but he warms up to her by the end of the second disc.
 * Hilarously played by Ryusei Date in Super Robot Wars. His obliviousness on the crushes of Mai Kobayashi and Latooni Subota was apparently because he's too busy swooning over girl-shaped Humongous Mecha, as in he's more interested to those things compared to human girls. And even though Lamia is a Robot Girl, he's still not interested at her, because she's not THAT huge compared to her robot, which he swooned at too.
 * This is also the trait of Masaki Andoh, who is just too oblivious that he has made himself one walking harem. It got worse that in his new home La Gias, polygamy was supported, and he gets confused on who to choose, so he probably picked none to avoid much confusion. His rival Shu Shirakawa also had a walking harem following him, but he playfully ignored them... to further antagonize Masaki and adding up with their Foe Yay angle.
 * This is Sonic's general attitude. Particularly towards self-appointed girlfriend Amy Rose. Awkward because he's saved her a few times in the past because he thinks of her as a good friend, but she takes as evidence that he loves her.
 * Sonic may actually be asexual, before STH 06 (and even afterwards) Sega actually made a clear point about Sonic having no interest in girlfriends, and, amusingly, didn't think to mention the "other option." But when Sega described Sonic as "footloose and fancy free" they could have been referring to his Walking the Earth lifestyle, his laid-back nature, his "lack of interest" or the latter.
 * It's different in the Archie comics though, where he gets involved in a Love Dodecahedron and something of an Unwanted Harem, Depending on the Writer. (a certain writer has a tendency to play these tropes up until others have to be brought in for damage control)
 * The same goes for Tails. In the comics, he has multiple girlfriends, in the games, Rouge flirting with him confuses him, and makes him think (correctly) that she has an ulterior motive.
 * Link of the Zelda games has been the target of flirtation from a number of female characters, but he seems to be more taken aback than tantalized. To be fair, in most of the games he's ten years old, but he seems no less innocent as Adult Link.
 * The Legend of Zelda Ocarina of Time is when it happens the most, and it's also when it's most justified. He's only ten, and even as Adult Link he only has the body of an adult. Then there's the fact that he was raised among the Kokiri. Who are kids for their entire lives. And most likely don't get involved in that sort of thing.
 * It's justified given the time period the games emulate. In the majority of the series, he starts out as an orphan (usually) in some tiny backwater before he heads out the grand adventure. Given such a conservative background, it's unsurprising he'd be a bit bashful and uncertain around people who take that kind of interest in him.
 * Hitman's titular character is kissed- on the lips- by a grateful rescuee, which results in a case of the jibblies one might get after grinding their nails over a chalkboard. Mind you, said rescuee was a kidnapped girl who had been forced into prostitution, so the 'jibblies' might just be Squick from wondering what that mouth's been doing recently. In the remade version of that mission in Hitman: Contracts, he just sneers at her grumpily. Agent 47 does seem to fit the trope, but that might have more to do with the only female in the games who isn't an unimportant civilian is his Mission Control.
 * Crosses over to The Movie, where Nika practically comes at him crotch-first at one point, and he actually uses a sedative to get her off him. Justified by the fact that 47 was bred to be a superior assassin, and a sex drive isn't very conducive to efficient killing.
 * Ryo Hazuki of the Shenmue series appears to not only be chaste, but asexual. Despite the very obvious advances of attractive females (Nozomi in Youkuska, and Joy in Hong Kong) stoic old Ryo can usually only muster a "Have you seen a black car?" when his love is clearly making advances. For all its sandbox and open-world play and decision-making structure, the complete lack of interaction options that make use of other characters' romantic feelings towards Ryo is quite jarring, as Chugworth Academy illustrates here.
 * While not actually physically chaste, sleeping with six different women throughout the storyline, Hakuoro somehow fails to realize they all love him until the very end. Oh, and the bunny princess also has a thing for him. It's most obvious with Karura, Yuzuha and Eruruw. And Urtoriy. Doriy and Guraa also express some interest, but they're more into Oboro. Seriously, that's at least nine and he only expresses vague awareness of two or three tops before the story ends.
 * By the time of Mega Man X 8, Zero's pretty much celibate, but he's also quite clueless to the feelings his new navigator has on him. On the other hand, after what happened last time he almost had a girlfriend, can't fault the guy for not being much for feelings.
 * In the Mega Man Zero series, it's questionable on how much he cares for Ciel on the "Love" scale as well (despite the latter being very obviously in love with him by the end of the series) - whether he's a Chaste Hero, a Celibate Hero, or simply too stoic to say anything out loud is left entirely ambiguous.
 * Vayne from Mana Khemia: Alchemists of Al-Revis, being raised by a cat for six years, he has no grasp on such a concept. When Nikki starts to develop feelings for him (mainly through her character quests), he remains absolutely clueless. At one point Vayne receives a letter; the others think it's a love letter, while Pamela says "This is Vayne we're talking about! That's impossible!"
 * Despite that Mayl's is obviously hitting on him, Lan in Mega Man Battle Network is mostly clueless about Mayl's feelings for him, although time to time he's aware, and
 * Sanada Yukimura from Sengoku Basara, a naive teenager who knows no life other than the battlefield, and is not only oblivious to any romantic feelings girls may have toward him, but also gets extremely embarrassed whenever anyone mentions such things as love, sex or relationships (which Keiji teases him about relentlessly). It doesn't help that the only mentors he has are Takeda Shingen and Sasuke.


 * While it never comes up in-story, the SPARTAN II's of Halo also bare mention as they quite literally are this trope, due to their sex drive being completely suppressed by their augmentations (specifically, the catalytic thyroid implant).
 * Terra from Final Fantasy VI is a Chaste Heroine, because she doesn't know What Is This Thing You Call Love?. The Figaro Castle guards, and even Edgar, are surprised that Terra didn't react negatively to Edgar hitting on her. She eventually learns about the feeling of love later, but she's probably still a Chaste Heroine.
 * In Pokémon, those Pokémon with the ability "Oblivious" is immune to being charmed.

Visual Novels

 * Saber in Fate Stay Night is completely impervious to sexual or even romantic innuendo unless it's pointed out to her. This is a popular joke in Doujinshi, where she usually thinks you're talking about food.

Webcomics

 * Sinfest has Criminy. Perfectly portrayed here. Bonus points for the red demon Fucshia having a crush on him but him being oblivious to it.
 * Recently he dug up a hole to hell to search for her, so he at least is fond of her.

Western Animation
"Phineas: Ferb and I are going to use a laser to carve our faces in the comet, so that when it passes over again in 73.5 years our grandchildren will see it. By the way, my parents are cooking outdoor steaks for everyone. What do you think, Isabella? Isabella: You had me at our grandchildren... Phineas: Huh? Isabella: Steaks! You had me at steaks!"
 * Ang from Legend of the Dragon is like this. He shows interest in a female once, but otherwise remains oblivious to the attentions of females.
 * Arguably, Hank Hill is one despite being married and in his late 40s. He has the same obliviousness to female attention, whether from his wife or any other woman. He is quite embarrassed by any display of sexuality, practically runs out screaming when he accidentally enters a porn section of a video store, and, in what is perhaps the best illustration of this side of his character, when he meets two young female nudists he winds up lecturing them on the benefits of propane heating for their summer home.
 * "Nobody rejects Debbie Grund!" "Well I just did!"
 * Another example: He was talking with a Doctor and behind him, there was a poster in the wall that displayed a women uterus and related organs, during the entire conversation Hank would try to avoid look at the thing.
 * He may have grown up with an older mindset about marriage and romance.
 * Eric Cartman from South Park is an anti-hero version of this trope. He seems to be more focused on making lives of others miserable and other things than romance.
 * Although in the "Le Petit Tourette" episode,
 * Ace Lightning - The titular main character doesn't even know how to flirt.
 * Phineas from Phineas and Ferb, who remains completely oblivious to his best female friend's repeated hints that she has a crush on him. The fact that his same-age (step)brother is a borderline Covert Pervert only emphasises this.
 * This dialogue shows this quite nicely:


 * Apparently, he still doesn't get it...
 * At the end of Across The 2nd Dimension, Isabella made sure he got it. However, she knew he wouldn't remember...
 * Freddy in the newest Scooby Doo series has become this trope. Ironically enough, the series cranks the historic Ship Tease Up to Eleven but he remains oblivious to all of Daphne's advances due to his obsession with solving mysteries and planting traps.
 * Zigzagged with Ensign Boimler in Star Trek: Lower Decks. In “Grounded”, he seems oblivious to the three young, attractive women at his family’s vineyard (Lianne, Mandolina, and Genevieve, the last of which looks just like the Sun Maid Raisin Girl for pete’s sake) who are trying to get in his pants. Although, in a later episode he does start to wonder if he’d been better off staying there and marrying Lianne.
