Nyan Koi



Junpei Kousaka is an Ordinary High School Student with an allergy towards cats and a family that loves the little beasties. Life is normal and fairly peaceful for him, right up until the part where he breaks a shrine that housed the Guardian Deity of Cats.

Suddenly, he finds that he can hear cats talk and they can hear him. If he wants to make up for his accident, he must do 100 good deeds for cats, lest he be turned into one himself and possibly die from the full-body allergic reaction.

An anime adaptation of the series aired in the fall of 2009, with a second season announced at the very end of the last episode. Nyan Koi is licensed by Sentai Filmworks and currently showing on the Anime Network with subtitles.

Tropes in Nyan Koi! include:
"Junpei: "I look like someone else? That's an illusion! I will shatter that foolish illusion!""
 * Abuse Is Okay When Its Female On Male: Poor Junpei, usually due to Kanako.
 * Accidental Pervert: Junpei ends up like this a lot, especially with Kaede. Accidentally copping a feel during the Beach Episode, for example.
 * A Cup Angst: After seeing the little "accident" Junpei had with Kaede, Kotone pats her chest.
 * Nagi frets about her small chest size.
 * Adaptation Expansion: To some extent. The manga is still quite young, and the anime is able to shoot through two chapters with one episode. Perhaps as a way to avoid Overtaking The Manga, some new storyline material has surfaced as early as episode 7 that wasn't part of the manga.
 * Ambiguously Gay: Junpei's friend Haruhiko, at least in his mannerisms. He's been known to buy eroge manga and was the one to start peeping on the girls during the Furo Scene mentioned below. However, he was all-too-willing to wear the maid outfit during the school festival...
 * And Call Him George: Kaede with cats in the first episode. She doesn't actually kill them, but her habit of luring them with food to hug and cuddle them freaks out the local cats. The first favor Junpei has to do for cats is to get her to stop.
 * And Now You Must Marry Me: Nagi often threatens Junpei with this if he keeps holding back his feelings for Kaede.
 * Applied Phlebotinum: At one point, Akari . However, she can't do it without eating pocky.
 * Armor-Piercing Slap: Akari's preferred method of attack, in contrast to Kanako and Nagi's Megaton Punch.
 * She did give him the Megaton Punch a couple of times though.
 * Artificial Riverbank: Where Kaede and Junpei meet a few times during Junpei's physical training.
 * Baleful Polymorph: What will happen to Junpei if he doesn't perform 100 good deeds for cats.
 * Battle Aura: Kanako and Nagi often have one, usually when they're jealous/mad at Junpei.
 * Beach Episode: More like Public Pool Episode, but still.
 * Beautiful All Along: Kanako normally dresses in an overexaggerated ganguro style, but beneath it she's actually pretty nice looking. After the maid episode, she completely abandons manba fashion.
 * Kanako's Beauty Mark under her left eye is more noticeable without the makeup.
 * Bifauxnen: Nagi looks boyish enough that even Junpei is mistaken at first.
 * Her personality does revert to a more girlish side whenever she sees lightning. Even her voice is radically different.
 * Big No: At the end of episode 1 (in Gratuitous English, no less!)
 * Bishie Sparkle: Happens to several characters, usually Junpei or Kaede.
 * Blue With Shock: Happens to a few characters, usually Junpei.
 * Brick Joke: When Ichinose Nagi first challenges Kousaka Junpei to a duel, she temporarily ducks and cowers when lightning, representing her passion, flashes in her own Imagine Spot. This seems to be completely played for laughs until, later in the same episode, a plot point reveals - in the same overblown humor - that Nagi has a crippling fear of lightning.
 * Also used for the note itself. When Kotone gives him her confession, he immediately thinks it's another challenge, and is surprised when it's actually a confession. When he shows up though, it's Akari who's waiting for him, and she does challenge him.
 * Butt Monkey: Everything in the world hates Junpei.
 * Nagi's grandfather is one to Nagi.
 * Cannot Spit It Out: Junpei has a really tough time telling his feelings for Kaede despite numerous opportunities. Both Kanako and Nagi are quite angry about it as well.
 * Catgirl: Every female member of the cast (and some males) are represented as one in the OP.
 * Cats Are Mean: Oh yes, yes they are. Poor, poor Junpei.
 * Subverted since the cats are grateful for the favors he does for them (not that he has a choice in the matter due to his curse). Only a subversion since the cats have no problems with demanding those favors.
 * Cat Smile: This is especially the default happy face of Junpei's sister.
 * Crash Into Hello: Junpei meets Kaede this way, although she sort of lands on his chest feet first. She proceeds to apologize and slap him silly to try and wake him up.
 * Clingy Jealous Girl: Kotone is very clingy when it comes to Junpei and has to be constantly dragged off by Akari. She does show jealousy when she perceives Akari as getting too close to Junpei in episode 10, but she doesn't really act on that.
 * Further proven when she gets upset when Nagi gets a little too touchy with Junpei in her drunken state, but again she does not act on that.
 * However, somewhat subverted by the fact that in the manga, she willingly steps aside to allow Junpei and Kaede to have some time together, noting that it was Akari who forced Junpei to go on a date with her.
 * While they tend to argue about it, Kanako doesn't like seeing Junpei with other girls.
 * Cloudcuckoolander: Kaede. She is unable to read the atmosphere at times and appears to go into another world entirely especially when it concerns cats and anything that has to do with her vision of manliness (having a Yakuza-style house for example).
 * It does seem supported from the manga though.
 * Color Failure: Happens to Junpei occasionally.
 * Colour-Coded for Your Convenience: Kotone and Akari, who wear black and white hair ornaments, respectively.
 * Furthermore, Kotone primarily wears clothes which are mainly black, as Akari wears clothes which are mainly white.
 * To summarize: Akari is a Tsundere, Kotone is a Yandere. Kotone is more dere, while Akari is more tsun.
 * Comically Missing the Point: Kaede interprets Junpei and Kanako's arguments with each other as being close friends, even if they're screaming at each other.
 * Conspicuous CG: The cat statue when its head first falls off.
 * Crash Into Hello: Junpei meets Kaede when she falls from a tree trying to rescue a cat. He tries to catch her, slips, and she lands feet first...on his chest...
 * Cross-Popping Veins: Happens to a few characters.
 * Cursed With Awesome: Being able to hear cat's thoughts wouldn't be so bad, if Junpei wasn't allergic to them. And that other thing about turning into a cat...
 * Debut Queue: The first several episodes of the anime add one or two girls to Junpei's Unwanted Harem each.
 * Different As Night and Day: Kotone and Akari Kirishima. Kotone is in love with Junpei (though only because she can't resist someone with that much misfortune) and Akari is against her sister being with anybody.
 * Dirty Old Man: Chizuru has been described as such by Junpei on a few occasions.
 * The monk plays this straight, and often dresses up to pick up women.
 * Does This Remind You of Anything?: In episode 7, the tip of Junpei's poking out of the water from between his legs in the hot spring.
 * Dropped a Bridget On Him: Inverted,  She is not happy about Junpei applying this trope to her.
 * Dude, He's Like In A Coma: When Junpei passes out from his fever, Kanako
 * Early Bird Cameo: Chizuru is seen delivering mail in the first two episodes, then is introduced in the third one.
 * Cute Kitten or cats in this case. It helps that Junpei's lovely ladies also love cats.
 * Expy: Poked fun at in the Eyecatch for episode 11.
 * Early Bird Cameo: Chizuru is seen delivering mail in the first two episodes, then is introduced in the third one.
 * Cute Kitten or cats in this case. It helps that Junpei's lovely ladies also love cats.
 * Expy: Poked fun at in the Eyecatch for episode 11.

"Nagi: "Oh my God! Pineapple!""
 * Eyecatch
 * Eye Take: In one episode, the cats that usually hang around Junpei kept on lecturing him, while at the same time, Kaede was having a cute conversation where she was trying to convey her feelings towards him while she was walking her dogs. Junpei was trying to listen to her, but the cats were talking so loud that he eventually couldn't take it anymore and shouted out for them to shut up. Everyone was so shocked by this sudden outburst that even Kaede's dogs had a clear "O_O" look on all of their faces.
 * Fan Art: Most shows with special end cards have them designed by published artists, but Nyan Koi! is letting the fans be the ones to make the show's end cards, resulting in a Contest Winner Cameo for whoever is chosen.
 * Fan Service: All over the place, particularly in episode 9 and the preview for the next episodes. Junpei's got a pretty good body too, as it turns out.
 * Fear of Thunder: Nagi's fear is so great that she cowers when thunder, representing her passion, claps in her own Imagine Spot.
 * Freudian Slip: Nagi: "I'm going to check out these breasts--No(in girly voice), I mean the other members.."
 * Furo Scene: In episode seven, although the fanservice is mostly female-oriented.
 * Genki Girl: Kaede Mizuno. She's a member of the Track and Field Club, so all that energy is being put to good use.
 * Chizuru falls into this trope from time to time, usually if Junpei is around her.
 * Genre Savvy: Harukhiko constantly jokes about Junpei being in a Visual Novel, and talking about events and flags regarding the main girls.
 * Gratuitous English: Played with at one point. Nagi calls Junpei and Kaede lovers, but she says it in English. Junpei stops and wonders why she said it in English rather than Japanese (meanwhile, the subtitles have fun with it).
 * Nagi's fond of Gratuitous English in general, actually.
 * Well, so is Junpei.
 * "JEEEEEEEEEEEEEEEE-SUS"
 * "THRILLEEEEEEEEEER!"
 * "Haruhiko, GOOD JOB!"
 * The in episode 10 says "shit!" at one point. If you're a native-English speaker it tends to Narm up the scene.
 * "Is this a so-called ROOOVUU RETAAHH!?"
 * Episode 7 also includes bit of Russian - that owner and cat pair (the cat is actually a real Russian consultant/VA Jenya), and apparently a comment about Japanese meditation in a later scene.
 * Junpei says "I'm okay" after getting slapped awake by Kaede in episode 3.
 * At the very end of episode 6, while talking to the Kirishima twins, Nagi spouts some rather interesting words:

"Nagi: Well, no wonder you failed your test. Looks like all the nutrition went to your tits instead of your brain!"
 * Hair Antennae: Kotone and Akari both have it. It is also one of the few ways to tell the twins apart; Kotone only has one, while Akari has two.
 * Hey It's That Voice: Tama is Lelouch cat!
 * Nyamsus is The Major cat!
 * Noir is Nia cat!
 * Nagi-sempai is Yuu Kobayashi. Try mixing Setsuna and Ayame.
 * Considering her character, Kaede/Kaere Kimura might fit better.
 * Kaede's voice may remind you of Index, while Chizuru is Mikoto.
 * Hot Mom: Averted; this is a rare contemporary Shounen Anime in which the mother isn't that bad looking but does indeed look like she's middle-aged.
 * Idiot Hair: Indicative of her naturally air-headed personality, Kaede has it.
 * If It's You It's Okay: Being the pervert that she is, Kotone often quietly admits in front of Junpei that she would gladly welcome anything he'd do to her if he wanted. Junpei usually either doesn't hear what she said, is to focused on more important issues at hand, or just doesn't know how to respond to her statements.
 * Imagine Spot: Several characters do this throughout the series.
 * It Got Worse: Hilariously happens to Junpei in episode 3. First he sees his two guy friends walking through the mall, and hides behind Chizuru, since he doesn't want to have to explain why he's hanging out with a girl. They pass by without noticing him, but then Kanako just happens to be passing by, and does see him. He runs off with Chizuru, and tries to hide in a grocery store, only to run into his sister. He then runs away again, and runs into a cat he helped in the previous episode. Her owner then comes out and tells him to come by sometime, making him flee again. Chizuru then delivers the last letter, and gives him a big hug. Sure enough, Mizuno just happened to be walking her dogs there. So much for his hope of Mizuno not seeing him helping Chizuru out and getting the wrong idea.
 * In episode 12, Junpei's curse of turning into a cat is sped up as a result of Kaede overhearing about Junpei's curse, and her suspicions about it.
 * I Want My Beloved to Be Happy: Played with. Nagi threatens Junpei with marriage in episode 5 if he won't give Kaede a Love Confession before the end of their day at the fair.
 * Kanako shifts back and forth between this and being the rival to Kaede in a Love Triangle with Junpei. One instance she'll deny having any feelings for him, then in the next she goes into Clingy Jealous Girl mode when she sees him hanging out with Kaede. Which only further serves to confuse Kaede if they're dating or not.
 * Karmic Transformation: Junpei will turn into a cat if he doesn't help at least 100 cats within a certain period of time. And if anyone finds out about his curse, it'll speed up his transformation.
 * Lampshade Hanging: During the Public Pool Episode both Junpei and Kaede thought they were going to the library to study, yet turn up in swimsuits in the next scene. Tama helpfully pops up and explains that they rented them.
 * Large Ham: Several characters, but usually Junpei or Nagi.
 * Limited Wardrobe: Nagi always wears the pants to her track suit. Even while wearing her school uniform's skirt.
 * Love Hurts: Kaede develops a sad look on her face in one episode after seeing Kanako yank Junpei away for some cleaning duties. It doesn't get lost on Nagi, who gets extremely upset that he made her feel this way, and sends a letter of challenge to him.
 * Love Letter Lunacy: What appears to be a love letter turns out to be a letter of challenge from Nagi. Which Junpei promptly ignores.
 * Later, Junpei receives one from Kotone, which Akari promptly grabs from him.
 * Meet Cute: Junpei and Kaede's first meeting involves her trying to rescue a cat from a tree and using Junpei as a landing pad.
 * And then she tries to slap him awake...
 * Love Triangle: Within the main three (Junpei, Kaede, and Kanako), it starts with a type 5, grows into a, and is now at a . Love is complicated.
 * Magical Girl: Akari and Kotone, apparently. Only Kotone gets the Transformation Sequence, though.
 * Magic Pants: Averted when,
 * Magic Skirt: In the manga and broadcast, Kotone and Akari seem to have some kind of portable shadow generator in their outfits. This goes away in the DVD Version.
 * Marshmallow Hell: Chizuru does this to Junpei in episode 3 to thank him for helping her deliver mail. Unfortunately for him, she does it just as Mizuno happens to be walking her dogs by.
 * Megaton Punch: Kanako's favorite weapon. Nagi's got one too.
 * My Name Is Not Durwood: Kanako often calls Junpei "Koubaka" (a portmanteau of his last name "Kousaka" and Baka.
 * Kanako calls Junpei "Nekouji" in the pool episode. It's a portmanteau of neko (cat) and ouji (prince) and translates as Prince Kitty.
 * Nagi's nickname for Kanako is D-Cup.
 * These are all Type D of this trope.
 * Ms. Fanservice: Pretty much all of the girls could be considered one, but Chizuru fits it the most. In one episode her only appearance is in some naughty underwear while spouting some random mailing stuff that doesn't add anything to the plot.
 * Nice Job Breaking It, Hero: The premise of the show. Junpei accidentally knocks the head off the cat statue, and gets cursed by having to help out cats and hearing their thoughts. And if he doesn't do it fast enough, or someone finds out about it, he turns into a cat himself.
 * No Sense of Direction: Chizuru. Which wouldn't be such a bad thing if she wasn't working for the post office. Cranked Up to Eleven for laughs for the MewView in episode 10: Chizuru somehow ends up in China, New York, and eventually, Antarctica.
 * Oblivious to Love: Junpei, something that Kanako grows increasingly frustrated with over the course of the series.
 * Ordinary High School Student: Junpei
 * Panty Shot: Junpei (though not the audience) gets one of these when he first ran into Kaede. "WHITE!"
 * Junpei once again gets it (twice, no less) during episode 6, once each with both the Kirishima twins. Moreover, the panty shots are shadowed out.
 * As is becoming standard for many anime nowadays, the audience gets a view of both these scenes on the DVD versions.
 * Pastimes Prove Personality: Kaede is seen renting a video...about mafia bosses fighting with each other. Not what Junpei was expecting.
 * She's also extremely psyched to find out that Nagi is a mob boss heir.
 * Pettanko: Kotone is visibly jealous of Kanako, but keeps it mostly to herself. Nagi doesn't bother hiding it.


 * Running Gag: Nagi is afraid of thunder/lightning because her grandfather constantly got hit by it as she was growing up.
 * Junpei will almost always be in a Not What It Looks Like situation whenever he runs into Kaede while with another girl. Or when he yells at the cats because they're pestering him while he's trying to talk to her.
 * Schoolgirl Lesbians: Episode 4
 * Subverted later on, when Nagi challenges Junpei to win Kaede over by the end of the day, or he'll have to get engaged to her.
 * Also subverted in that very episode when Nagi explains she's not actually gay, but an "appreciator of beauty." So...bi-curious?
 * School Festival: With Maid Cafe.
 * Both Kaede and Kanako were Meido for their class Maid Cafe. Junpei was bowled over by Kaede's look, while the whole class was amazed with Kanako, especially since everyone was seeing her for the first time without Manba hair and makeup.
 * Secret Keeper: Junpei promises not to tell anyone about Nagi's fear of lightning, and also says he'll be there if she needs him. Which causes Nagi to start developing a crush on him...
 * Junpei is forced to do this with himself, as revealing the curse to anyone else not only speeds up his own curse, but also affects that person. The Kirishima twins are exempt since they have magical charms/amulets that protect against it. To everyone else, Junpei just looks weird spending a lot of time with cats, considering he's allergic to them. The twins sometimes utilize this aspect of it to get him to do things.
 * Sequel Hook: The end of episode 12 plainly says that there will be a Season 2, but nothing seems to be forthcoming so far...
 * Shout Out: The Kiyosumi High School girls and two Tsuruga Academy girls make an appearance at ep 4.
 * In episode two, there's a cameo of the two heroines of Onegai Twins.
 * Episode eight. The Cat of the week has some interesting eyesight.
 * Episode 11's Eyecatch.
 * See Watanabe Shinichi below.
 * Shipper On Deck: Nyamsus of all characters shows signs of being a Junpei/Kanako supporter. Junpei's family on the other hand seems to ship him with the Kirishima twins
 * Speaks Fluent Animal: Junpei, but only with cats and not by choice.
 * Spit Take: A frequent sight in the series.
 * Spoiler Opening: While it's definitely not hard to tell that Nagi is a woman, her appearance in the opening as a catgirl (along with the rest of Junpei's love interests) three episodes before she even appears in-series makes one wonder why it was treated as a surprise at all.
 * Stalker With a Crush: Kotone, who stalks Junpei and keeping a fantasy diary which involves her and Junpei.
 * In episode 8, she goes as far as bugging Junpei's house, and even contemplates installing a hidden camera in there just to spy on him. Stalking taken to new levels.
 * Standard Snippet: The "here are our sponsors" jingle is "Flea Waltz". In Japan, the title is "I've stepped on a cat" (titles from some other countries also have something to do with cats).
 * Funnily enough, in Russia it's knows as "Doggy Waltz"
 * Souvenir Land: Tokiwadai Land, complete with some sort of cat creature that looks to be the park's Mickey Mouse.
 * Stealth Hi Bye: Nagi instantly appears in episode 5 after her name is mentioned by Kanako while they're having lunch in the classroom.
 * Nagi does it again in episode 8.
 * Suspiciously Specific Denial: In episode 6, Kanako claims she's not interested in hearing Junpei's friends gossiping about him going after a twin-tailed girl, but she insists they tell her anyway. Nagi uses a similar threat.
 * Thanks for The Mammary: Nagi does this to Kanako in episode 4. Hilariously, she squeezes it again after about a 2 second delay from the first one, before Kanako finally uppercuts her.
 * Junpei finds out Nagi is a girl this way as well later in the same episode.
 * Theme Tune Cameo: Junpei is shown hearing the OP song on his headphones as he's walking, early on in Episode 1.
 * Those Two Guys: Haruhiko and Kouta, Junpei's two guy friends who are seen occasionally in his class.
 * Transsexual:
 * Tsundere: Akari's attitude towards Junpei fits, as does Kanako's. Both are Type A Tsunderes.
 * Twelve-Episode Anime
 * At least until Season 2.
 * Unlucky Childhood Friend: Kanako, though her relationship with Junpei is a lot more turbulent than usual.
 * Unwanted Harem: Junpei looks like he's developing this. Of course, taking care of the cats is more of a priority over this.
 * Watanabe Shinichi: Nabeshin shows up as a bus driver early in the seventh episode.
 * What Do You Mean It's Not Awesome?: The comedy in the series basically runs on this.
 * Yandere: Kotone.
 * Zettai Ryouiki: Both the Kirishima twins. Akari's a Grade S while Kotone's a Grade A.
