Characters from Oreimo include:

Kirino Kousaka

Voiced by: Ayana Taketatsu

14-year-old Kirino, the titular imouto (little sister), is a model student with excellent grades, competent athletic skill and great popularity. On the other hand, she's also an Otaku with a fetish for imouto Eroge. Kyousuke discovering her double life is what starts their first serious interaction in years. Eventually, Kirino opens up her otaku personality more thanks to her brother and gains friends in that world.

Kirino claims she keeps the 2D and 3D worlds separate, but gets irritated when she sees Kyousuke interacting with other girls. It gets to the point where she claims she has a boyfriend just to make Kyousuke (who has Kuroneko) jealous. In the eighth volume of the Light Novel, after Kuroneko dumps Kyousuke, Kirino pulls a role reversal, comforting him and confronting Kuroneko about breaking his heart. After a heated argument, she admits that she was about to ask Kyousuke not to date anyone, but decided to let Kuroneko have him because she recognized how hard it must have been for the shy Kuroneko to get the courage to ask him out. She admits to being a brocon at the end. This is reflected throughout volume nine. She's still a tsundere, but much more open about the brocon/siscon relationship she and Kyousuke have.

  • The Ace
  • Alliterative Name
  • Big Brother Attraction:
    • Even she seems aware that something's off about this, as she vehemently shuts down anything that refers to it directly. The Visual Novel strongly implies this anxiety is most of the reason for her general tsuntsun behavior towards Kyousuke. However, that does not stop her from playing eroge based on this and Brother-Sister Incest.
    • In volume nine of the Light Novel, she's openly comparing how much of a siscon her brother is with Sena, and even gives Kyousuke a False Start confession at the end.
    • By volume ten, Kirino and Kyousuke are often seen holding hands, and are the subject of some rumors around the neighborhood. Yoshino forces Kyousuke to move out, ostensibly to study for exams, but also to separate the two from getting too close as she sees it.
  • Brutal Honesty - She's both blunt in her honesty sometimes but very dishonest at other times, especially when it comes to her affection.
  • Catch Phrase - Kimo (basically a juvenile way of saying "gross!") and Saiaku (in context, "you're the worst").
  • Character Exaggeration - The anime greatly ups her tsuntsun.
  • Clingy Jealous Girl - Kirino tends to get a bit snippy if Kyousuke's been spending a lot of time without her, especially if she knows it's with another girl.
    • She suppresses this impulse in Volume 8 to allow Kuroneko and Kyousuke to date unmolested, even though it eats her up inside.
    • Her jealousy also shows up a lot in the Visual Novel, where she will likely confront Kyousuke at some point in anyone's route asking where he has been.
      • She goes as far as to move away again in one of Manami's endings.
      • She also has a rather heartbreaking exchange when she finds out Kyousuke and Ayase are dating in Ayase's route. Interestingly, Kirino will accept their relationship only if Kyousuke confesses to her that he loves her as much as he loves Ayase, which leads to the famous "Ayase baby" ending where she happily supports their relationship in the present and the future.
    • In episode 6 of the anime, she kicks his door and his chair at the table. Despite having a new hugging pillow, she can't fall asleep because she knows he's sleeping at Manami's house.
    • Later in episode 11, she gets incredibly annoyed at Manami being at their house, and sets ridiculous demands such as cleaning their living room, which Manami more than happily agrees to. Later she tries to sabotage Kyousuke by placing her laptop in his room with an eroge playing, as well as laying a bunch of his porn mags on his bed. It hilariously backfires as Manami isn't offended at all, but rather is intrigued that all of those mags and the eroge have Meganekko girls...
  • Closet Otaku - Finding people to talk to about her hobby is what kicks off and drives the plot for the first few volumes.
  • Cry Cute - Already broke down crying in frustration [dead link] in the first light novel alone (Episode 3 of the anime, Chapter 10 of the manga) while confessing to Kyousuke that their father had discovered her eroge and scolded her badly.
    • Again in Episode 15 (True End), when she confesses to Kyousuke how much she missed playing them throughout her stay in America.
  • Cute and Psycho - In a hidden route of the PSP Visual Novel, Kyousuke and Kouhei discover an 8-bit shrine under their hotel in Kyoto. Akagi wishes on the shrine that they're never separated from their little sisters for the rest of their lives, and as a result Kirino turns scarily overprotective, getting the Ayase-style murder eyes, forbidding Kyousuke from meeting or mentioning anyone besides her and then gripping him so hard she breaks his arm right at the end.
  • Cute Little Fangs
  • Defrosting Ice Queen - Towards Kyousuke. Kirino is the somewhat rare Tsundere that fits both the original and the modern definition.
  • Eroge - Plays these as part of the Periphery Demographic of little sister games.
  • False Start - Kirino says something that's drowned out by the crowd noise at the end of volume 9. Whether it's just a thank you or a confession is left unresolved, but Kyousuke seems to have gotten the message.
  • Hair Colors - Her hair is explicitly stated to have been dyed that color right at the start of the light novels.
  • Hard Work Hardly Works - Completely averted. Kyousuke notes that Kirino is not really talented at running, but she makes up for that by training really, really hard. Unfortunately, this falls apart when she is pitted against people who both trains equally hard AND are really talented.
  • It's All About Me - Kirino starts out like this, but improves greatly over the course of the story. It's implied later on that she acted like this earlier to hide her embarassment in typical Tsundere fashion.
  • I Want My Beloved to Be Happy - After the incident with Kyousuke telling her he doesn't want her dating other guys, she was about to tell him the same when she found out Kuroneko was about to confess to him. She decides that being jealous is better than Kyousuke being sad and denying her best friend a shot at happiness, especially knowing how shy Kuroneko really is.
  • Jerkass - Cranked Up to Eleven in the anime, which no doubt left a sour note for some viewers. Of course, Character Development turns her into a Jerk with a Heart of Gold.
  • Lack of Empathy - Although even anime Kirino seems to get some eventually, as shown in Episode 9 when she plays an eroge and finds herself in Kyousuke's shoes. This is explicitly pointed out in the DVD Commentary and expanded on in the PSP Visual Novel.
  • Laser-Guided Amnesia - In the PSP Visual Novel, Kirino catches this through a combination of her jealousy towards Manami going with Kyousuke on the class trip and Kuroneko pointing out how similar Kirino's situation is to an eroge and telling her that she would lose sense of reality. It only affects her memory of anything related to her otaku hobby, including all development of her relationship with Kyousuke. The "convenience" of how exact this is is lampshaded immediately and repeatedly.
  • Younger Sibling Fetishization - She is one herself and plays these kinds of games exclusively.
  • Lolicon - (Debatable) To some extent.
  • Male Gaze - The shots of her ass in the animeand the manga. Kyousuke even coolly says "nice ass" to her in the in-character DVD Commentary when this particular shot comes up.
  • Manic Pixie Dream Girl - Kirino is manic to an extent, and looks the part, but it's actually Kyousuke who brings Kirino out of the solitude caused by her hobby. On the other hand, Kyousuke also starts to have a much more interesting life as a result of his actions, so it works both ways.
  • Mary Sue - In-Universe: other characters (such as Kuroneko) are annoyed at how perfect she is at (almost) everything. In fact, the reason why her relationship with Kyousuke had originally deteriorated was because of his jealousy of her success. Subverted in that she did work hard to earn her skills plus most of them prove worthless at getting her anything she wants which usually results in Kuroneko or Kyousuke getting it for her.
  • Ms. Fanservice - This isn't really a fanservice series (one can even count the total amount of Panty Shots on the hands), but almost all fanservicey shots come from Kirino.
  • Not Blood Related - In an If route (which is even less canon than the other routes of the PSP game), Kyousuke discovers that he's not actually Kirino's brother. As soon as both siblings are aware of this, they almost immediately start a relationship. The night Kirino finds out, she tells Kyousuke to sleep[1] with her so she can be sure he won't move away now that he knows he's not related to the family.
  • Otaku Surrogate - Her taste in anime and eroge. Said anime and eroge are often aimed at older men. In one scene in the PSP Visual Novel where she's attending a Meruru live event, her line while screaming like a maniac is tagged "Otaku" instead of her name.
  • Put on a Bus - She is away in America for most of Volume 5 of the light novel and the ONA episodes.
  • Panty Shot - The camera does not want to cooperate with those short skirts she likes to wear.
  • Red Oni, Blue Oni - The red to Kyousuke and Kuroneko's blue.
  • Talking To Herself - Taken to massive levels of meta in the DVD commentaries, where Kirino interviews her own seiyuu on how it was like to voice herself.
  • Tsundere - Kirino in the anime is a Type B towards Kyousuke and Kuroneko and very heavy on the tsuntsun; other versions are much more evenly balanced. All, eventually, defrost to at least some extent. The PSP If route where she and Kyousuke are Not Blood Siblings heavily implies that the heavy tsuntsun is entirely because of her anxiety about her Big Brother Attraction. When that obstacle is removed she immediately goes 90% deredere, and tells Kyousuke that she actually always liked him, even before the events of the story.
  • Vitriolic Best Buds - With Kuroneko, no matter how both of them deny it.

Kyousuke Kousaka

Voiced by: Yuuichi Nakamura

All 17-year-old Kyousuke wanted was a normal life—a boring job, a boring wife, etc. -- save for his lack of communication with Kirino for years. All that changes when he finds a Magical Girl DVD case with an Eroge inside after bumping into Kirino. He's then brought into Kirino's world as her confidant and helps her along the way. Along the way Kyousuke begins to see things more and more in an Otaku life, eventually using Visual Novel terms in his decisions and choices.

Kyousuke is easily intimidated by Kirino, but stands up for her when needed and takes a lot of the abuse that should be directed at her. Although he claims to hate her, the main driver of the plot is his gradually thawing relationship with Kirino.

  • Alliterative Name
  • Big Brother Instinct - A major plot point is that he was so jealous of Kirino's success that he turned this instinct off until the beginning of the series.
  • Bishonen - A borderline example. He's arguably full blown in the manga, though.
  • Brother-Sister Incest - People like to joke about how close Kirino and Kyousuke are. The novels started out pretty vague, but in Volume 9 he and Kouhei actually have a contest about whose little sister was cuter. Kyousuke actually wins the later contest their little sisters have over whose brother is the biggest siscon.
  • Casanova - DVD Commentary Kyousuke is quite good at chatting up any female co-hosts, even if the lines shouldn't really be working so well...

Kanako: You say those heart-melting lines to all the girls, don't you?
Kyousuke (sparkling) : Don't misunderstand. You're the only one I've asked about the color of her panties.
Kanako (blushing): Oh...in that case, I'll let it slide...

  • Covert Pervert - For whatever reason, he becomes obsessed with breasts in Volume 8 of the Light Novel.
  • Cry Cute - A rare male example, courtesy of Kirino actually apologizing to him. In the anime, it's after she throws him a Meido party as restitution for disgusting him with her appalling treatment of Manami. In the novel, it's after said party ended up a failure, with Kyousuke being pushed too far by Kuroneko's manga and Kirino and Kuroneko beaning him over the head with a chair for seeing their 3D analogues get stripped naked in a custom Siscalypse game Saori brought.
  • Deadpan Snarker
  • Fan Nickname - "Brosuke"
  • I Just Want to Be Normal - Kyousuke's outlook on life before he reconnects with Kirino. He starts going through withdrawal symptoms when she's not around.
  • In-Series Nickname - He's called "Sexual Harassment Sempai" by Sena, Kuroneko repeatedly calls back to this whenever she perceives him acting a bit perverse.
  • Master of the Mixed Message
  • Oblivious to Love - Manami's anyway. He gets a bit better with Kuroneko. He goes to a rather frustrating extreme in Manami's route of the PSP game, where he continues to be kind of blase about the whole thing even after they start going out, while Manami is practically exploding with adoration for him.
  • Red Oni, Blue Oni - The blue to Kirino's red.
  • Secret Keeper - For Kirino's hobby.
  • Tsundere - Just like his sister. Just look at the series title...
  • Unlucky Everydude
  • Unreliable Narrator - Part of the reason Kirino is generally more lovable in the novels is because Kyousuke is giving a biased account of her, edited through the filter of his initial dislike and denial of her and her feelings.
  • Vitriolic Best Buds - His relationship with Kouhei fits this trope to a T.

Ruri "Kuroneko" Gokou

Voiced by: Kana Hanazawa

A member of the same online community as Kirino and Saori, as well as a Foil figure for Kirino. A fan of Maschera (which looks like a lovechild of Code Geass, Death Note and Darker than Black), her arguments with Kirino about the direction anime is going can sometimes be construed as arguments on the genre as a whole. Despite their arguing they are quite close to each other.

Kuroneko's relationship with Kyousuke also developed quite a lot. First seeing him as an older brother who does just about anything for his bratty younger sister, she tells Kirino that's she's jealous and calls Kyousuke "nii-san". In the 5th novel she starts attending Kyousuke's school and at that point calls him sempai. And at the end of volume 7, they enter a relationship.

  • A Day in the Limelight - Two of the four net episodes focus on her, as is the case with volume five of the light novel.
  • Audio Erotica - In-series, Kyousuke is a bit stimulated when he hears Kuroneko's voice in the vocal foley for a game they were making.
  • Clingy Jealous Girl - It doesn't come up in the anime, but Kuroneko is very possessive of Kyousuke. In the Visual Novel, she mocks Kyousuke when meeting him going out with Manami in that route, and rats him out in a pretty cowardly fashion to Kirino in Ayase's route. She outright states she did the latter because of her jealousy.
  • Cool Big Sis
  • Cosplay Otaku Girl - Almost all the time, except when she's in her school uniform or in that white sundress she wears once she becomes Kyousuke's girlfriend.
  • Elegant Gothic Lolita - A combination of this, her hair and her body type make her look noticeably younger than Kirino even though Kuroneko is a year older.
  • The Gadfly - Especially evident in Episode 11 of the anime, where she writes a manga with thinly-veiled expies of Kirino and Kyousuke just to get a reaction out of them.
  • Green-Eyed Monster - Kuroneko was the one who originally came up with the "lay a trap with Kyousuke's Porn Stash when Manami comes over" plan out of jealousy, although this is omitted from the anime. See also Clingy Jealous Girl.
  • Hime Cut
  • It's All About Me - Like Kirino, she's not as selfish as she looks at first glance.
  • Lack of Empathy - She gets better.
  • Little Miss Snarker
  • Loners Are Freaks - She doesn't get along well with her class, although Kyousuke keeps meddling to get her to socialize a bit more. It works.
  • Love Triangle - Kuroneko, Kyousuke and Kirino are the main love triangle. She ends up going out with Kyousuke in Volume 8 of the Light Novel, only to break up with him at the end of summer. This is partly because she realizes that she likely can't win against Kirino in the end, as well as not wanting to hurt her friend (see this disturbing drawing in her journal lamenting that feeling [dead link]). The end of the volume implies that she'd quite like to be together with both of them.
  • Panty Shot - Saori bluntly points out that Kyousuke might be getting quite a view from Kuroneko in the first scene of the Visual Novel, which serves as an introduction to the real time conversation system as he desperately tries to calm Kirino down. There's also a blink-and-you'll-miss-it one in Episode 13.
  • Red Oni, Blue Oni - The blue to Kirino and Sena's red.
  • Relationship Upgrade - Becomes Kyousuke's girlfriend in the eighth Light Novel...then breaks up with him at the end of their summer vacation.
  • Short Dark And Bishoujo
  • Spin-Off - Kuroneko has her own manga, Ore No Kouhai Ga Konna Ni Kawaii Wake Ga Nai (My Underclassman Can't Be This Cute).
  • Tenchi Solution - The end of Volume 8 implies she's in favor of this answer to the Love Triangle problem. She blurts out that she's okay with Kirino and Kyousuke <censored>ing in volume 10.
  • Tsundere - Much lighter on the tsuntsun than Kirino, but still very much one. She's a Type A in that she is mostly cold to everyone, but can be very sweet towards Kyousuke, the object of her affection. This contrasts with Kirino's Type B.
  • Vitriolic Best Buds - With Kirino—no matter how much either denies it—and to a lesser extent, Sena.
  • Yamato Nadeshiko - When Kyousuke first meets her, he thinks that she has the appearance of a traditional Japanese beauty. Her personality, however, couldn't be further from this type.
  • Younger Than They Look - Because of her fashion style and body type, Ruri looks younger than her peers and even characters younger than her, like Kirino and Ayase.

Saori "Saori Bajeena" Makishima

Voiced by: Hitomi Nabatame

Moderator of Kirino and Kuroneko's home online community, Saori looks like a stereotypical Otaku who uses weird speech mannerisms, uses really thick glasses (with swirls), and wears awkward clothing. But don't let first impressions fool -- Saori is actually a wealthy socialite who is quite traditionally beautiful. She even has an impeccable fashion sense and speaks in a traditional high-class style while not playing as "Saori Bajeena". Volume 9 reveals that she got both her otaku fashion sense and her speaking style from Kanako's older sister Kanata, who even gave her the swirly glasses.

Saori is quite close to Kuroneko and Kirino, considering them both her closest friends, even having to stop them from tearing each other apart sometimes.

  • Arranged Marriage - In the PSP game, Saori is engaged by her parents to a 40(!) year old business heir who wants her to throw away her otaku hobby. The main plot driver of her route is Kyousuke getting her to stand up to her parents and fiance to defend her identity.
  • Beautiful All Along
  • Cat Smile - You'll see it in the manga and a few times during the anime.
  • Cool Big Sis - To Kirino and Kuroneko.
  • Cosplay Otaku Girl - She comes up with the idea of the maid party for Kyousuke to apologize for Kirino and Kuroneko planning the Porn Stash trap for Manami to find. The anime implies this was partly to have an excuse to dress herself and her friends in custom made maid outfits she ordered. Also, in the PSP game, she shows Kyousuke a stack of cosplay photos she took to try and "get the otaku urges out" of her in preparation for her Arranged Marriage, including a Sarashi Bikini kind of outfit that makes Kyousuke do a Spit Take.
  • Demoted to Extra - She had more page/screen time in the original light novel as well as A Day in the Limelight, which from all indications will get no coverage in the anime aside from a slight reference. She does appear more in the ONA episodes, and gets a route in the PSP game.
  • Embarrassing Nickname: Sure, Saori's chosen surname of "Bajeena" may be a well known Gundam character, but to those uninitiated to anime it sounds awkwardly like a prominent part of the female reproductive anatomy, so much so that Kyousuke did a massive Spit Take from shock when he first heard it.
  • Huge Schoolgirl - Subverted big time. She's a cheerful leader type with excellent social skills, defying any height complex and the socially inept otaku stereotype.
  • It Was a Gift - Saori's glasses, and really her whole otaku persona, were borrowed from Kanako's older sister Kanata, who Saori admired.
  • Meganekko
  • Nerd Glasses - Invoke to give an Otaku image.
  • Nice Girl - A kind and friendly ray of sunshine who can be friends with anybody, and does not hold grudges towards those who are judgemental of the anime community.
  • The Ojou
  • Otaku Surrogate - Even plays up the part by wearing stereotypical Otaku clothes.
  • Playing Against Type - After a decade of playing emotionally-reserved and dead-serious warriors like Kanu Unchou of Ikki Tousen, Hitomi Nabatame finally sinks her teeth into a bright and upbeat role like Saori.
  • Secretly Wealthy
  • Shipper on Deck - For Kyousuke and Kuroneko.
  • Shrinking Violet: She used to be one.
  • Tall, Dark and Bishoujo
  • Team Mom - Again to Kirino and Kuroneko, both in the forums and in the outside world.
  • They Do - In the best ending of her Visual Novel route, she marries Kyousuke while they're still in high school due to her parent's prodding. This is pretty abrupt since, unlike the other routes ending in marriage, before the last scene their relationship isn't treated as definitively romantic at all.
  • Verbal Tic - Usually ends her sentences with "De gozaru". In general, she talks in the way an otaku would think a ninja would talk.

Manami Tamura

Voiced by: Satomi Sato

Kyousuke's childhood friend and probably the simplest member of the cast. Plain and wearing glasses, she has a crush on Kyousuke and spends lots of time with him. Kyousuke knows nothing about it; nevertheless, he finds Manami comfortable and considers her part of the family.

Kirino dislikes Manami, most likely due to the fact Kyousuke spent more time and is in a better relationship with her than his own younger sister. As such Kirino insults/ignores her whenever she sees her. Kuroneko acts this way too when she starts seeing Kyousuke as more than just a friend.

  • Babies Ever After - Manami's best ending in the PSP game has her giving Kyousuke some nice tea after they're married, and nonchalantly telling him that she's pregnant. Kyousuke's reaction is excited happiness, to say the least.
  • Beware the Nice Ones - It's hard to tick her off, but she's apparently very scary when she is angry. So scary even Kyousuke cringed at the possibility of angering her in the eight light novel.
  • Blind Without'Em
  • Childhood Friend Romance - Hasn't worked out so far in the novels, but she's an option in the PSP Visual Novel.
  • Foil - Manami is what Kirino is not: nice to Kyousuke, plain, and almost pathologically normal in every way. Kyousuke makes this comparison himself when she's first introduced. No wonder Kirino (and eventually even Kuroneko) dislikes her.
  • Generic Cuteness - She's not considered that good-looking In-Universe, but through this trope she looks about as cute as the other girls, odd haircut notwithstanding.
  • In-Series Nickname - Kuroneko calls her "Belphegor" even before actually meeting her, based on Kirino's stories that she's a seductress underneath that sweet exterior.
  • Meganekko
  • Nice Girl
  • Odd Friendship - She became friends with Ayase at some point.
  • Out of Focus - She becomes less and less prominent in the later novels.
  • She Cleans Up Nicely - An If route shows her becoming an idol with a different hairstyle and no glasses, and she arguably looks as cute as the girls who are professional models. Of course, Generic Cuteness may be in effect here.
  • Shipper on Deck - She tells Kyousuke to go after Ayase in the eighth volume of the light novel.
  • Turn the Other Cheek - She takes the jealousy-motivated rudeness from Kirino and Kuroneko in stride and doesn't even seem cross with them.
  • Yamato Nadeshiko - As far as her personality goes, she's probably the closest girl in the show to the ideal Japanese wife.

Ayase Aragaki

Voiced by: Saori Hayami

Kirino's classmate, coworker, and best friend. Ayase can be very protective of Kirino and cares for her quite a bit. However, accidentally learning of Kirino's hobby causes a rift that Kyousuke has to fix (by sacrificing his dignity and claiming he is "corrupting" Kirino with his eroge collection). After that she tolerates Kirino's hobby and tries to support her.

Ayase initially thought Kyousuke was a cool older brother and maybe even had a little crush on him, only for that to change to contempt after being fooled by Kyousuke into thinking he is "corrupting" Kirino. However she'll still go to him for help with making up with Kirino along with getting her items related to her hobby.

  • Alliterative Name
  • Babies Ever After - Only a possible ending with Kyousuke in the PSP game, so it's not even remotely canon. Nevertheless, it caused quite a stir when it was leaked before the game's release.
  • Broken Pedestal - How she saw Kyousuke after he sacrificed his dignity and claimed he is "corrupting" Kirino. Still that does not stop her from approaching him whenever she needs help concerning Kirino.
  • Distant Finale - Her (in)famous Babies Ever After ending takes place an unspecified amount of time after the main story, but Kirino has been modelling professionally in Europe for at least a few years and freaks out over the prospect of being an aunt since that means she's getting older.
  • Defrosting Ice Queen - Towards Kyousuke in the Visual Novel as well as the light novel. She actually gets mad at him for "lying" about wanting to marry her in the Light Novel. This plot thread gets expanded to a full relationship in the Visual Novel.
  • In-Series Nickname -
    • Kyousuke loves calling Ayase "Lovely My Angel" as part of his flirting.[2]
    • "Lovely My Angel Ayase-tan" is the name of a fanblog of Ayase in Volume 10.
  • Moral Guardian - Ayase basically plays this role for the show over the subject of eroge. She does, however, start to loosen up and contacts Kyousuke to get Kirino the best gift she can (which would naturally be otaku-related).
  • Odd Friendship - She became good friends with Manami at some point during Kirino's stay in America.
  • Only Six Faces - She looks quite similar to Kirino doesn't she? Even her hairstyle is almost the same.
    • Fridge Brilliance - they're models, it would make sense that they would be chosen for that kind of appearance and hairstyle.
  • Tsundere - Ayase turns from a Yamato Nadeshiko type, to a Yandere, to this by volume 10.
  • Unprovoked Pervert Payback - The epic kick she gave Kyousuke sort of fits into this category. Unlike his relationship with any other girl, though, Kyousuke actively flirts with Ayase any chance he can get in the Light Novel and Visual Novel, so this may not be so unprovoked.
  • Vitriolic Best Buds - With Kyousuke after he fools her into thinking that he is "corrupting" Kirino. There are indications that the reason she still talks to him is because she doesn't really believe his story, but accepted it anyway to stay friends with Kirino. She confirms this in the PSP Visual Novel.
  • Yandere -
    • Ayase kills Kyousuke pretty abruptly in one ending of her route, which Kyousuke sees coming, telling the player to save before the decisive Two Shot scene. She also gets a few moments where her murder eyes come out, but for the vast majority of the route and the game she's as sweet as she was when she first met Kyousuke. In her Distant Finale she even outright states that she has since grew out of her jealous streak.
    • Played with in volume 10 of the Light Novel, where Ayase produces a kitchen knife out of nowhere as a housewarming gift for Kyousuke's new apartment. Kyousuke understandably panics, and Ayase wonders why he freaked out so easily just because he saw her with that knife.
  • Yamato Nadeshiko - She grows into, well, a full time version of her "nice girl mode" in her PSP route's Distant Finale.

Kanako Kurusu

Voiced by: Yukari Tamura

Another of Kirino's classmates and model coworkers. Kanako has several layers, the first being a cute, short, musically talented girl. The second is a cold, heartless bitch. Beneath all that, however, she might just be a regular girl in the end after all.

Kanako constantly goes to karaoke and tries out at idol competitions. She's even able to sing a song she's only heard once perfectly. All this comes in handy when Ayase tricks her into cosplaying as Meruru at an event to win an item for Kirino. Despite winning, Kanako feels disgusted. However, she enjoyed being praised and the event goes on to further her career.

In Volume 9, Kanako gets Ayase to bring back the manager (aka Kyousuke), because he was her first fan. It also implies that she would be okay with Kirino's hobby because her older sister Kanata is a mangaka.

Daisuke Kousaka

Voiced by: Fumihiko Tachiki

Father of Kyousuke and Kirino. He has a no-nonsense home policy, which fits nicely with his career as a police officer. Despite his gruff exterior, he cares greatly for his family even if he doesn't show it. He even has clippings and articles all about Kirino's job.

In the first novel he discovers Kirino's hobby and orders her to throw it all out. After Kyousuke convinces him to allow Kirino to keep it, he researches more into the otaku lifestyle to understand it better.

Daisuke: "...but don't get me wrong, I didn't do this for your sake."

Yoshino Kousaka

Voiced by: Akeno Watanabe

Kyousuke and Kirino's mother and the force binding the family together. She happens to know about Kirino's hobby and Kyousuke's Porn Stash.

Kouhei Akagi

Voiced by: Junji Majima

Kyousuke and Manami's classmate, and Sena's older brother. Kouhei keeps wondering why Kyousuke hasn't started dating Manami yet, even after he got Kyousuke to admit that he wouldn't let anyone date Manami.

Like Kyousuke, his little sister is an Otaku... except their relationship seems to be more risque than that between the Kousaka siblings.

  • Beta Couple - His relationship with Sena is quite similar to Kyousuke and Kirino's relationship, and often compared to theirs in the light novels. A major difference is that he has no problem with saying his sister is cute. At one point in the DVD commentary, when a possible Spin-Off is teased he says the name would have to be "My Little Sister is Cute!", causing much Tsundere blushing on Sena's part.
  • Brother-Sister Incest - Implied, with Sena. It's to the point where he was looking to buy a sex doll that looked just like Sena... which he saw while he was buying her a gimp suit in a porn shop for her "research."
    • In volume 9, he has a contest with Kyousuke over whose sister is the cutest. Sena wins after kissing Kouhei on the cheek for a picture.
  • Handsome Lech - Kouhei is implied to be quite good looking and popular with the ladies. Of course, we only ever really hear about his relationship with his little sister and the perverse otaku baggage that brings...
  • Shipper on Deck - For Kyousuke and Manami.
  • Vitriolic Best Buds - He and Kyousuke have a relationship surprisingly similar to that between Kuroneko and Kirino, although not as intense.

Sena Akagi

Voiced by: Mariya Ise

A Class Representative, member of the Game Research Club, and Kouhei's younger sister. Sena seems to be a responsible, hard-working girl and acts more like a Student Council member than a Game Research Club member. But all that's a facade—Sena is quite the hardcore fujoshi.

She and Kuroneko don't get along very well, which makes the fact that they share both the same class and club all the more frustrating for each other. Eventually, however, their relationship begins to mirror that between Kuroneko and Kirino when the former has to ask her help on her game.

She and Kirino meet at the summer Comic Market during the summer break and become fast friends. She introduces Kirino to Boys Love, while Kirino talks to her about eroge, and both compare notes about their relationships with their older brothers. They have a contest to determine whose brother is the most siscon. Sena admits defeat after hearing that Kyousuke flew to America to bring Kirino back as well as breaking up with his girlfriend for her.

  • Beta Couple - Her relationship with her brother is remarkably similar to that of Kirino and Kyousuke, except with no pretense of hating each other.
  • Brother-Sister Incest - Implied, with Kouhei.
  • Buxom Is Better - She is an E cup, and she has some minor Gainaxing going on in the anime as a result. Kyousuke's internal monologue lovingly focuses on her breasts sometimes.
  • Class Representative - At first glance she fits the trope in both name and personality. However, past the diligent student exterior she often gets fired up over her hobby and mushy around her brother.
  • Covert Pervert - She generally seems mostly normal, but when relaxed enough that she actually talks about her fetishes, things get... really interesting.
  • Fiery Redhead - Concerning her fetish.
  • Hypocritical Humor - Gets all bent out of shape when Kyousuke mentions an Eroge, calling him "sexual harassment sempai". After seeing her game presentation, Kyousuke calls her "sexual harassment kouhai."
  • In-Series Nickname - The aforementioned "sekuhara sempai/kouhai" (literally "sexual harassment senior/junior") names she and Kyousuke call each other.
  • Meganekko
  • Nightmare Fetishist - At first, she just seemed like a yaoi fangirl. And then her game came along and had anal fisting up to the entire arm; necromancer yaoi, and anal using the hilt of the Masamune. All in a single scene. She's actually surprised this proposal is rejected.
  • Red Oni, Blue Oni - The red to Kuroneko's blue.
  • Serious Business - Her Yaoi
  • Shipper on Deck - For Kirino and Kyousuke. Specifically, "Kirino-kun" and Kyousuke, which she draws in a doujinshi that she sends Kirino.
  • Tsundere - She's a Type B in that she only acts deredere to her brother Kouhei. This is especially obvious in the DVD Commentary for Episode 13, but can be seen in her interaction with him on the phone during the actual episode as well.
  • Yaoi Fangirl - So much so she fantasizes about one of her clubmates getting gangraped by the other members. Cue looks of horror and disbelief from her fellow club members when she blurts this out.

  1. ↑ what definition of sleep is ambiguous, but she's putting on her kissy face while she says it
  2. ↑ Incidentally, Kirino has what looks like a case/box with "Lovely Angel" on it in the box of her personal effects that she shows Kyousuke the night before she leaves, with a silhouette that looks very similar to Ayase. This may be the source of the nickname.
