aka: Ore No Imouto Ga Konna Ni Kawaii Wake Ga Nai
The character sheet for Oreimo
Voiced by: Ayana Taketatsu14-year-old (later 15) 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 Little Sister Heroine 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.
- Alliterative Name: Kirino Kousaka.
- 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 9 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 10, 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.
- Kirino always wanted to marry her brother since she was a little girl. They eventually start dating and hold a fake wedding. They do break up and say they will be normal siblings though it is implied that they are still secretly together at the end of the novel.
- No longer implied, based on the new Afterstory it's clear that she still 'bragging about her love' with Kuroneko
- Big Brother Worship: Used to idolize her brother when she was younger before he went onto a Broken Pedestal in her eyes.
- 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.
- On the other hand, the manga does the same, but with her deredere side.
- 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 and episode 8 of season 2 to allow Kuroneko and Kyousuke to date unmolested, even though it eats her up inside. He's rather surprised by her lack of reaction when he tells her he's dating Kuroneko.
- 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 first season, 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 Mega Nekko girls...
- After seeing Kuroneko and Kyousuke getting along a bit too well in episode 6 of season 2 and volume 7 of the light novels, Kirino initiates Operation Jealousy on him, by claiming to be dating Mikagami, the boy they met at comiket earlier who's an Otaku and works at the same agency as her.
- 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◊ 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.
- Once more at the latter half of Volume 7◊ (Season 2 Episode 6), as she's venting out her frustrations at Kyousuke over spending more time with Kuroneko and Manami than her.
- 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: She sports these,and they become especially evident when playing eroge.
- 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 Heroine 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.
- First Name Basis: The fact that she's on one with Kyousuke is a given reason why their parents send him off to live by himself for a bit. They saw it as them getting a little too close (and considering they think the siscon eroge are his).
- Groin Attack: Attempted by her to Kyousuke in episode 4. She succeeds in episode 5. Also serves as a bit of a Kick the Dog moment as Kyousuke was trying to help her when she did it.
- Hair Colors: Her hair is explicitly stated to have been dyed that color right at the start of the light novels.
- Happily Married: She marries Kyousuke in a fake wedding in the final episode of season 2, then they immediately break up to just be normal siblings.
- 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 embarrassment 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.
- Jerk with a Heart of Gold: The Jerkass factor is cranked Up to Eleven in the anime; otherwise she's more balanced between being mean and nice in all other adaptations; all versions, though, undergo Character Development that helps bring out her better personality traits.
- Kick the Dog:
- Kuroneko was rather hurt by Kirino's declarations of not knowing her and Saori, with the added comment of them being disgusting, despite Saori's assurances that she didn't really mean it.
- Kirino also does this to Manami in Volume 4 of the Light Novel and episode 11 of the anime. She does this by pretending to have forgotten who she is, badgering her at any opportunity, and then trapping Kyousuke by spreading his porn all around his room for her to see. Both Kirino and Kuroneko (who actually came up with the idea according to the Light Novel) realize they went way too far, and throw Kyousuke a surprise party as an apology.
- 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.
- Little Sister Heroine: She is one herself and plays these kinds of games exclusively.
- Lolicon: To some extent. All the signs are there, of course, but Kirino is zany enough that her more modest explanations, questionable as they are, could be taken at face value.
- Love Epiphany: A second type. Kirino always love Kyousuke, but her Big Brother Attraction keep making her deny her feeling. At least until he confessed.
- 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.
- 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.
- No Sense of Personal Space: Kirino, specifically her waking Kyousuke up by climbing on top of him. Note that she does this before they start hinting she had a crush on him; that's just how she wakes him up.
- 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 sleepnote with her so she can be sure he won't move away now that he knows he's not related to the family.
- Obfuscating Stupidity: She comes off as bubbly and obsessed with her hobbies, but the anime and manga make it clear that she is very crafty and manipulative. On a good day, she's also an excellent liar and skilled at otherwise hiding the truth.
- 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.
- Parody Sue: Other characters (such as Kuroneko) are annoyed at how perfect she is at (almost) everything — academics, athletics and even modeling. Except she actually worked hard to earn her skills, and has to rely on Kyousuke or Kirino to help her in matters relating to anime, manga, games or light novels. Come Volume 11, it is revealed that the reason Kyousuke is also annoyed at her present self is because she reminded him of his former self, and subsequent developments reveal that Kirino's talents sprang from her attempts to "surpass" her brother.
- Pet the Dog: Kirino gets some rare moments where she's genuinely or at least somewhat nice to Kyousuke.
- The first is in the second half of season 1, when she throws the maid party with Saori and Kuroneko to thank him for all his help and advice.
- The second big one is in episode 9 of season 2, after Kuroneko breaks up with him. While she does put him in a chokehold move briefly, she does seem to go out of her way to help him find where Kuroneko went and why she suddenly dumped him.
- 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.
- Tears of Joy: At the end of episode 14 of season 2, after nearly two year of self-denial and inner struggling, she finally accepted the fact that she loves Kyousuke more than as an older brother, and shed tear of joy when he confessed to her.
- Troll: There were moments when she enjoy teasing others, like when during her fake date with Kyousuke, when she taunted Kuroneko about her 'current relationship' with him.
- Also, on the Collaboration project, she made fun of Mikoto, saying that while the railgun series has '22 volumes, 2 gaiden books, 7 New Testament volumes, 1 additional side story book, 3 anime seasons, 8 new gaiden volumes', Mikoto still didn't manage to get any closer to Touma, while her had been 'living together with my love interest for 15 years, was confessed at the end of volume 2, entered a love hotel together in volume 3'
- 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.
- Used to Be a Sweet Kid: There was a time when she was a cute, loving little sister. Then Kyousuke broke her heart because he had to give up the cool figure he always presented to her. No wonder she starts acting so aloof towards her big brother.
- Vitriolic Best Buds: With Kuroneko, no matter how both of them deny it.
Voiced by: Yuuichi NakamuraAll 17-year-old [later 18] 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.
- Abhorrent Admirer: Invoked by him for fun. Flirting with Ayase until she attacks him seems to literally be how he gets his kicks. He tries to tone it down later in the series, because he can see where it can be misleading and dishonest when its just for fun.
- The Ace: Resembled one of these three years ago with good grades, a good amount of athleticism and an overzealous enthusiasm for helping people.
- Adorkable: In-universe, most of his friends consider him awkward and a little pathetic at times, but endearing. Interestingly, very rarely does anyone actually see his competent and determined side, which the audience knows is what usually saves the day.
- Alliterative Name: Kyousuke Kousaka, just like his sister.
- 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.
- Bishōnen: A borderline example. He's arguably full blown in the manga, though.
- Broken Ace: Essentially gave up trying to be special due to events revealed in volume 11.
- Broken Pedestal: Kirino used to idolize him when she was younger because he excelled at everything. But then he started becoming lazier, which shattered his image in Kirino's eyes.
- 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.
- The 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...
- Chick Magnet: Canonically, he at least has Manami, Kuroneko, and (as of season 2) Ria, Kanako and Ayase crushing on him (with Kuroneko becoming his girlfriend temporarily). In the PSP game, he can romance Saori, Ayase, and, with the right ending, even Kirino herself.
- Clueless Chick Magnet: See above. Despite all of this, he never seems to piece out their intentions.
- Covert Pervert: For whatever reason, he becomes obsessed with breasts in Volume 8 of the Light Novel.
- Crazy Jealous Guy: Acts rather hostile towards Mikagami, Kirino's boyfriend at first, to the point where Kirino slaps him and forces him to leave the room when she invites him over to her house to meet their parents.
- 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.
- He does this again in episode 15 when he's trying to get Kirino to come back home. She isn't convinced of his reasons at first, but he breaks down and essentially says that he misses her, and wants to be "greedy" in not letting her go away again. This finally convinces her.
- And yet again in episode 9 of season 2, after Kuroneko breaks up with him, transfers schools, and refuses to answer any of his calls or texts.
- Death Glare: He can give a seriously nasty one if he's in the right mood, at least in the manga.
- Double Standard: Abuse, Female on Male: Poor Kyousuke ends up on the receiving end of this a lot, especially from Kirino and Ayase.
- Dude, Where's My Respect?: Kyousuke goes through great lengths to help Kirino's secret hobby become accepted by their father and her best friend Ayase. He also helps her to meet Saori and Kuroneko, which she forms a strong bond with and would never have met on her own. And even though he didn't really want to, he plays the gal games and eroge that Kirino dumps on him. Despite this and more, she still treats him like dirt for the most part.
- Guile Hero: Often, he's left with no recourse but quick thinking, fast talking, and the occasional Zany Scheme to get himself or his friends out of hot water.
- The Heart: He's the one who keeps Kirino and their friends together, whether through mediating between them or just listening to their problems and trying to help them. Saori even threw him a maid-party to show her appreciation of this.
- Hidden Depths: In-universe, to some extent. Judging by the not-really-canon-but-generally-reflective-of-it in-character DVD commentaries, most of the other characters in the show aren't really aware of how self-sacrificing or determined Kyosuke can be. Saori and Manami are astounded (speechless, even) when seeing for the first time the scene where Kyosuke convinces his father to let Kirino continue her anime and gaming hobbies, throwing his own reputation out the window and risking a beating. Even though Saori already had a thing for Kyosuke, she still considered him vaguely pathetic up until that point.
- Hypercompetent Sidekick: To, well, just about everyone. While he'll occasionally blunder through obstacles, he successfully solves so many other people's problems that Oreimo might as well be titled "Hypercompetent Sidekick: The Series".
- 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.
- Not to mention "Sexual Harassment Manager" after Ayase lies her ass off to Kanako and says Kyosuke was fired from being Kanako's manager due to hitting on Ayase too much.
- Large Ham: He tends to do this from time to time, such as telling his dad the eroge games were his, and that he was forcing them on Kirino.
- Master of the Mixed Message: He tells Kouhei that he's not dating Manami, has no intentions of doing it, but also won't be okay if she dates another guy. Later on, Ayase claims he's a pervert who likes to sexually harass girls. He doesn't deny it, but claims he only does it to her, to the point where she gets mad at him because he jokingly promised to marry her.
- Nice Guy:
- One of his defining qualities. Although he hates to do it, he will often go to great lengths to help out Kirino, even if its largely unappreciated, and this is one of the main reasons why so many of the girls in the series fall in love with him.
- It's not at all limited to Kirino—he'll do the same for just about anyone who asks him for help with anything.
- Not So Above It All: In episode 2 of season 2, Ayase complains to Kyousuke that Kirino is way too obsessed with one of her newest gal game. He promises to help her snap out of it, and when he talks to Kirino later, she makes him play the game as well. He starts getting into the game just as much as Kirino did, to the point where he makes the same goofy faces Kirino did, and brushes off Manami in a very rude manner.
- 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.
- Official Couple: With Kirino...temporarily
- Red Oni, Blue Oni: The blue to Kirino's red.
- Secret Keeper: For Kirino's hobby.
- Spit Take: He has a couple, complete with beautiful "blahargh!" noise and coughing fit.
- Tsundere: Just like his sister. Just look at the series title...
- 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. On the other hand, the manga also shows Kirino to be very vulnerable and awkward at times, which Kyosuke also can't perceive.
- Vitriolic Best Buds: His relationship with Kouhei fits this trope to a T.
- What You Are in the Dark: A consistent element in his characterization is that the majority of his friends never see him at his best moments and are generally oblivious as to just what he's capable of.
Ruri "Kuroneko" Gokou
Voiced by: Kana HanazawaA 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-Cup Angst: In episode 8 of season 2, she puts on an entirely new outfit which Kyousuke says makes her sexier. When she asks him what makes it sexier to him, he mentions that it makes her boobs look a little bigger. She then dejectedly walks away, forcing him to carry her bags and chase after her.
- 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, and episodes 7 & 8 of season 2.
- Aroused by Their Voice: Kyousuke is a bit stimulated when he hears Kuroneko's voice in the vocal foley for a game they were making.
- Cat Girl: Kuroneko cosplays as one in episode 11. Kirino hates to admit it, but she finds the ears and tail very appealing.
- Clingy Jealous Girl:
- It doesn't come up in the anime during the first season, 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.
- In volume 10 of the novel and episode 11 of season 2, she also butts head with Ayase, and claims that Kyousuke's soul belongs to her. Ayase doesn't take that very well.
- Cool Big Sis: Her younger sisters rely on her and adore her and she does a lot of house work when her parents aren't around, clearly marking her as the reliable type. She is also an avid and experienced Gamer Girl which any youngster will tell you is damn cool.
- 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.
- Don't You Dare Pity Me!: Kuroneko lashes out at Kyousuke when he seems to try too hard to help her.
- Eating Lunch Alone: She does this at least once after she transfers to Kyousuke's school.
- 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.
- Gamer Girl: Her skills at gaming are not seen often but when they are she's proven to be really good at games too. She's also interested in making games herself. This even becomes plot-relevant as she manages to beat a pro gamer and win a price which she then gives to Kirino.
- 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: Although, in this case she has this because she's mirroring the style worn by an anime Gothic Lolita.
- Insult Backfire: During episode 11 of season 2, Ayase calls Kuroneko a pervert after the latter say some rather interesting things regarding Kyousuke and Kirino. Kuroneko says she doesn't care about that.
- It's All About Me: Like Kirino, she's not as selfish as she looks at first glance.
- Lack of Empathy: She gets better.
- Large Ham: At times.
- Little Miss Snarker: Despite her shortness she can give some gloriously snarky comments, which combined with her tendency to go Large Ham provides a lot of funny dialogue/scenes.
- 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◊). The end of the volume implies that she'd quite like to be together with both of them.
- Older 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.
- 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.
- Polyamory: 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 ing in volume 10.
- Red Oni, Blue Oni: The blue to Kirino and Sena's red.
- Relationship Upgrade: Becomes Kyousuke's girlfriend in the eighth Light Novel and episodes 7 & 8 of season 2...then breaks up with him at the end of their summer vacation.
- Romantic Runner-Up: And probably because of the above, ended up bringing Kyousuke and Kirino even closer together than before. He ends up rejecting her in the OVA's for season 2, and while she ultimately accepts it, she screams out in anguish and curses him too.
- Spin-Off: Kuroneko has her own manga, Ore No Kouhai Ga Konna Ni Kawaii Wake Ga Nai (My Underclassman Can't Be This Cute).
- Sugar and Ice Personality: She is mostly cold to everyone, but can be very sweet towards Kyousuke, the object of her affection. This contrasts with Kirino's Tsundereism
- Vitriolic Best Buds: With Kirino — no matter how much either denies it — and to a lesser extent, Sena.
- What the Hell, Hero?: Gets called on this in episode 9 of season 2, after suddenly breaking up with Kyousuke, then refusing to answer his calls or texts, moves away, and transfers to another school without telling him.
- 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.
Saori "Saori Bajeena" Makishima
Voiced by: Hitomi NabatameModerator 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: In the anime, she can be seen very briefly without her glasses in the mirror in one episode. She is first seen fully without them in episode 3 of season 2, and is completely shocked by the fact that her friends caught her off-guard without them on when they attempted to visit her for a surprise birthday party. Kirino later mentions this trope to her.
- 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.
- 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.
- Foreshadowing: In the manga, when Kyosuke says he's having trouble with Kirino's video-games, she prescribes a regimen of taking a rifle, going everywhere with it, taking turns at right angles and swiveling like a turret to turn, FPS-style. We later learn that her older sister was an extreme gun-nut, introducing Saori to the world of obsessive fans that she would later embrace. Although her sister more or less dumped her for a husband later on, their bonding through gun-play was the turning point in Saori's life.
- Freeze-Frame Bonus: In episode 15 of season 2, when Kirino and Kuroneko are having yet another fierce debate about Meruru, she and Kyousuke are sent flying when the two girls initiate their usual dramatic anime-esque battle. While Kyousuke is reasonably seen with a freaked out expression Saori is positively squeeing.
- Huge Schoolgirl: Subverted. She's a cheerful leader type with excellent social skills, defying any height complex and the socially inept otaku stereotype. Double Subverted in that she actually is cripplingly shy; the otaku persona is a coping mechanism with which she practices the only real social skills she knows. The first meeting she has in the series with Kuroneko, Kirino, and Kyosuke? That was her first time trying to make new friends, too.
- It Was a Gift: Saori's glasses, and really her whole otaku persona, were borrowed from Kanako's older sister Kanata, who Saori admired and introduced her to anime and manga.
- 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: When she takes off her glasses and drops her otaku persona.
- Opaque Nerd Glasses: Invoke to give an otaku image. Turns out those glasses were given to her by a friend.
- Otaku Surrogate: Even plays up the part by wearing stereotypical Otaku clothes.
- Out of Focus: She is a supporting character at best in the first season of the anime, whereas in the light novel she's given much more emphasis. Episode 3 of season 2 averts this trope by devoting it entirely to her back story, giving much needed characterization and how she became an Otaku Surrogate in the first place.
- Platonic Life Partners: She's the only one of the main girls that doesn't fall in love with Kyousuke. Averted in the visual novel if you play her route though.
- Screw the Rules, I Have Money!: While it doesn't really seem like she does anything too different, in episode 11 of season 2, while all of the girls are fighting over Kyousuke, he mentions that ever since they found out about her other life, she seems to flaunt her money quite a bit more openly, after she says she's the best person due to her wealth.
- Shipper on Deck: For Kyousuke and Kuroneko.
- Shrinking Violet: She used to be one. In her first meeting of her sister Kaori's friends, as seen in episode 3 of season 2, she hides her face behind her hands when she first introduces herself to them. She gradually grows out of this trope over time.
- 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.
Voiced by: Satomi SatoKyousuke'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. It's revealed that she's the cause of the Kousaka siblings' cold war. She is thus, by default, the main antagonist of the series.
- 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. She's also the main reason Kirino and Kyousuke have such a bad relationship
- In episode 16 of season 2, after having been Demoted to Extra for a very long time, she finally snaps when she has a "final fight" with Kirino. Kyousuke thought they were just going to talk, but Manami literally delivers a gut punch to Kirino to let her know how she feels regarding their relationship. Perhaps not too surprisingly, she's the only one they've told who isn't pleased at all about it.
- Big Bad: The main problem for a while was Kirino and Kyousuke's strained relationship, Manami started that strained relationship, do the math.
- Bitch in Sheep's Clothing: Manami seems like the sweetest, most down-to-earth girl in the lot, but she's quite capable of destroying those that anger her. She convinced Kyousuke to idolize mediocrity, ruining him in Kirino's eyes, and when Kirino confronted her about it, she unashamedly told her that she was creepy and sick for loving her brother; in one fell swoop her words, deliberate or otherwise, destroys the siblings' relationship, brings about Kirino's vicious behavior, and ultimately is implied to have inspired Kirino's love of little-sister Eroge.
- Blind Without 'Em: Manami cannot see well without her glasses. A common thing between her and Kyousuke in the original light novels has him playfully swiping her glasses while she blindly tries to take them back.
- Childhood Friend Romance: Hasn't worked out so far in the novels, but she's an option in the PSP Visual Novel.
- Clingy Jealous Girl: She doesn't show this until episode 16 of season 2, but she is not happy that Kyousuke and Kirino are going out, going so far as to get into a No-Holds-Barred Beatdown with Kirino, delivering a What the Hell, Hero? speech combined with an Anguished Declaration of Love to him.
- Derailing Love Interests:
- Near the end, it is revealed that she destroyed the Kousaka siblings' relationship years ago out of jealousy. On top of that, she dragged Kyosuke down to become lazy and apathetic, so he wouldn't be out of her league, by manipulating his self esteem and guilt over some accident during mountain trip. There was little to no indication that she was anything but that cute and plain childhood friend before this reveal.
- The novel made it unclear when it comes to this matter. She didn't destroy Kirino and Kyousuke's relationship, but when Kyousuke was very vulnerable due to his failure with Sakurai, she gave him some advice (unclear if she did it intentionally or not). And while that advice seemed good in her POV, Kyousuke interpreted them in a way that caused him to turn lazy, which in turn destroyed his relationship with Kirino.
- Final Boss: One part of the final episode is a fight between her and Kirino. It's even called a Final Battle In-Universe.
- 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.
- I Want My Beloved to Be Happy: She seems to be an Unlucky Childhood Friend towards him, and seems okay with him dating other girls.
- Jerkass Has a Point: Her criticism of Kyousuke's relationship with Kirino was brutal and her fight with Kirino may have gone too far, but she had a valid point when she told them of how difficult it'd be to have an incestuous relationship. Kyousuke even acknowledges that she's right, but goes for it anyway.
- Morality Pet: Towards Ayase. In the Light Novel, Ayase's Yandere tendencies usually goes away by talking to Manami.
- Nice Girl: Subverted in Volume 11. Persuading Kirino that her feelings of admiration towards Kyousuke were unnatural, and convincing Kyousuke that the reason for his troubles was his exuberance, and that he'd be happy living a life of Dismotivation, basically creating the Kousaka Cold War.
- Odd Friendship: She became friends with Ayase at some point. In the anime, she claims that she ran into Ayase a few times in various places after he introduced them in an earlier episode.
- Out of Focus: She becomes less and less prominent in the later novels and most of season 2.
- 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.
- Tranquil Fury: Surprisingly even when she's mad, she doesn't lose her composure too much. The exception is in episode 16 of season 2, when she snaps and attacks Kirino after the latter taunts her about having "stolen" Kyousuke away, but even then, shortly after Kyousuke breaks up the fight, she seems eerily calm when she's asking him a couple of ArmorPiercingQuestions, and later slaps him while smiling and telling him his reply of choosing Kirino over her was the worst possible one.
- Turn the Other Cheek: She takes the jealousy-motivated rudeness from Kirino and Kuroneko in stride and doesn't even seem cross with them. However, unlike everyone else whom they've told about their relationship, in episode 16 of season 2, she does avert this trope and attacks Kirino when the latter taunts her repeatedly about having "stolen" away Kyousuke.
- Walking Spoiler: She became one in season 2, when it was revealed that she is the closest the series has to a Big Bad.
- Yamato Nadeshiko: As far as her personality goes, she's probably the closest girl in the show to the ideal Japanese wife.
Voiced by: Saori HayamiKirino'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 (which, she kinda did), 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: Ayase Aragaki.
- Anguished Declaration of Love: To Kyousuke in episode 12 of season 2 of the anime
- 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.
- Bitch in Sheep's Clothing:
- How she seems to act towards Kyousuke most of the time, partly because of him "corrupting" Kirino, and partly because he often teases her, such as jokingly asking her to marry him, which she uses against him a couple of times in the later novels. She does eventually utilize this trope less and less however.
- She seems to act this way towards Kanako a lot, such as smacking her in the face in episode 1 of season 2. In episode 10 of the same season, Ayase wonders if Kyousuke is making Bridget nervous, but the latter denies it. Bridget is actually afraid of Ayase due to the mean look she makes when talking to Kanako.
- Bi the Way: In episode 2 of season 2, after Kyousuke plays a new game that Kirino was getting too obsessed with, he tries to explain to Ayase what the game was like, and how the girl in the game looks and sounds almost exactly like her. As he explains it, she misunderstands him and with an excited expression, asks if Kirino wants to be lovers with her. He immediately rejects that notion.
- 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.
- Character Development: Part of her Defrosting Ice Queen route. As time passed on, she became more accepting of Kirino's hobby and even tried to think of ways to connect to her through that. She also warmed up to Kyousuke over time in the form of Belligerent Sexual Tension which culminated in a Love Confession.
- Clingy Jealous Girl:
- In volume 10/episode 11 of season 2, she visits Kyousuke in his apartment early in the morning. Kuroneko arrives shortly afterwards, and both girls butt heads a bit as to why the other girl is visiting him so early, and at all for that matter. Ayase claims that since they broke up, Kuroneko shouldn't even be visiting "onii-san". But Kuroneko wonders what kind of relationship Ayase has with him, since she treats him like dirt.
- A few chapters later, she also gets jealous that even Kanako is making food for Kyousuke while he's living alone. In episode 11 of season 2, when seeing Saori for the first time, Ayase eyes widen quite a bit at seeing yet another rival. Moments later, both Ayase and Kirino rush outside upon seeing Kanako handing Kyousuke some food, and both girls hilariously have the same exact movements and expression on their faces as they ask why he seems friendly with their friend.
- 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.
- In episode 6 of season 2, when Kyousuke innocently asks her if Kirino has a boyfriend, she activates Yandere mode in her eyes, and begins questioning him on it. Her eyes scare him so much he crawls to the other side of the room, causing her to wonder why he did that.
- Defrosting Ice Queen: Towards Kyousuke in the Visual Novel as well as the light novel and season 2 of the anime. She actually gets mad at him for "lying" about wanting to marry her in the Light Novel and season 2. 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.note
- Her contact data appears under this nickname in Kyousuke's cellphone in season 2.
- "Lovely My Angel Ayase-tan" is the name of a fanblog of Ayase in Volume 10.
- Kyousuke loves calling Ayase "Lovely My Angel" as part of his flirting.note
- Knife Nut: When she's taking care of Kyousuke during his prolonged study session, she gets him to study by non-lethally threatening him with a kitchen knife. She also flails it around when she finds some porno rags in his place.
- Love Confession: Gives one to Kyousuke at the end of episode 12 in season 2. He rejects her, stating he already loves someone else, and she doesn't take it too well at first. But she eventually accepts his decision.
- 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).
- Murder Simulators: In episode 5 of the Anime. Ayase finds out that Kirino is into Eroge, and begins rattling off about some case of a guy who claimed to play the games, and killed a girl. She then proceeds to take it Up to Eleven, Jack Thompson style.
- 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. However, 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 kicks she gives 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.
- 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.
- In episode 2 of season 2, after playing the gal game Kirino and Kyousuke were playing earlier, Ayase develops that look in her eyes when she mentions wanting to team up with Kirino to kill onii-san (Kyousuke). Kirino is immediately put-off and declines it, while Kyousuke, who was watching from a short distance away, immediately realizes Ayase took the Yandere route in the game.
- She has that look on her face again when Kyousuke asks her if Kirino has a boyfriend in episode 6 of season 2. It freaks him out so much that he crawls away to the opposite side of her room. She then wonders why he did that.
- In a Flash Back during episode 10 of season 2, she gets a call from Manami regarding Kyousuke's girlfriend. The first thing Ayase mentions is killing her, but Manami calms her down to tell her that they broke up.
- It's to the point where she uses this when Kyousuke rejects her love in episode 12 of season 2, claiming while teary-eyed she'll kill him if he doesn't go out with her.
- In one of the anime ending themes, a chibi version of Ayase with a murderous, toothy grin on her face and a knife in her hand is running furiously towards what is supposedly an unknown soon-to-be stab victim. While little kitchen knives are flying in the background. And her episode titles are generally marked with drawings of knives.
- Yamato Nadeshiko: She grows into, well, a full time version of her "nice girl mode" in her PSP route's Distant Finale.
Voiced by: Yukari TamuraAnother 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, though the praise she received ultimately inspired her to go full-time.Come Volume 9 (Season 2 Episode 10), 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.
- A-Cup Angst: She's self-conscious about being flat-chested and undeveloped in the Visual Novel, to the point of teasing Kyousuke about being a lolicon when he shows some attraction to her. In both the Light Novel and the Visual Novel, she basically forces Kyousuke to fondle her chest.
- Alliterative Name: Kanako Kurusu.
- Ascended Extra: She gets her own mini-route in the PSP game, as an offshoot of Ayase's route. In the sequel, her route is extended to be the same length as the other girls. The omake novel that came with the PSP game has Kyouhei married while living with his parents. Despite the fact that the wife is never named, it is implied by the exchange that the wife is Kanako.
- Bitch in Sheep's Clothing: Acts cheerful when a job prospect comes up, but when not working or if the job turns out to be fake, she immediately loses interest. However, like Ayase, she starts to show her good side.
- Blackmail Is Such an Ugly Word: In her mini-route, Kanako blackmails Kyousuke into paying for various activities in return for not telling Kirino that her "manager" was Kyousuke. Rather than blackmail, she calls it "courteous service for a lady," which Kyousuke can't help but laugh at.
- Clingy Jealous Girl: In Volume 10/episode 11 of season 2, she wonders why Kyousuke is eating food made by other girls, when he should only be eating food she made for him. This while she herself is learning to cook (from Manami, who she got in touch with through Ayase). Like with Ayase, she butts heads with Kuroneko on this subject.
- Genre Savvy: In Season 2 Episode 1, after Kirino returns from America, Ayase happily greets her. Kanako wonders if they're going lesbian, then immediately corrects herself and says it must be Yuri instead. It's because her sister Kanata likes those sorts of things too, hence why Kanako used that term despite not knowing about Kirino's hobbies at the time.
- Hates The Job Loves The Lime Light: In Season 1 Episode 10, Ayase fooled her into wearing a Meruru costume due to her uncanny resemblance to said character. Although offstage she gripes about it, while she's performing on the stage, she seems to give herself entirely to the act as she sings and wows the audience.
- Jerk with a Heart of Gold: Beneath that crass attitude she is surprisingly a decent person, going so far as to quickly accept Kirino for who she is upon learning of her secret hobby.
- Lethal Chef: When she first tries to make some food for Kyousuke in Season 2 Episode 11, he states that it's not very good. She mentions that she's learning to cook in an attempt to mend her relationship with her parents.
- Love Confession: To Kyousuke during one of her concerts
- Odd Friendship: She more or less befriends Bridget, the blonde girl she beat during the Meruru cosplay contest (who didn't have a very good impression of her offstage). At one point in the novel, Kanako protects her against an older man who seemed to be getting a little too frisky with her, only to find out that it was her father, but Bridget nevertheless appreciated the thoughts behind Kanako's attack.
- Panty Shot: There's one in Volume 4 of the Light Novel while she's doing the Meruru show. Also, on the DVD Commentary she shares an anecdote where Kirino asks what color panties she's wearing and flips up her skirt, much to Ayase's consternation. She does this while playing Kirino's panty shots up to that episode in the anime on the monitor in the background.
Voiced by: Fumihiko TachikiFather 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.
- Drowning My Sorrows: During Season 2 Episode 6, after Kirino comes home with Mikagami.
- Jerk with a Heart of Gold: "You... you... bastard son! Do as you wish! I DON'T GIVE A DAMN ABOUT IT!"
- Overprotective Dad: When Kyousuke discovers him drinking himself out upon seeing Kirino with a boyfriend, he tells him that he refuses to give Kirino to anyone, and was even willing to risk his job as a police officer by knocking him out. Fortunately Kyousuke manages to talk him out of doing it, and says he'll go instead, since he feels the same way.
- The Patriarch: The moment Kirino's dad finds out about her otaku nature, he doesn't take it well. After some damage control by Kyousuke, he reduces the condemned material to hentai. Once Kyousuke takes the heat for ownership of the hentai (see below), the father follows up a Kick the Dog moment (punching Kyousuke in the face) with a Pet the Dog moment (grudgingly, reluctantly, and indirectly allowing him to keep the hentai).
- Pet the Dog: He has his moments, even if he isn't happy about issuing them (as seen at the end of Volume 1 and episode 3 when, with a frustrated expression on his face, he orders Kyousuke to do as he wishes with the eroge, even if he wants to keep it all, right after punching him in the face for being a siscon).
- Reasonable Authority Figure:
- He had to be convinced about Kirino's hobby, but he also doesn't restrict his kids, such as not allowing Kirino to use her money how she wants, nor does he actively meddle in their affairs constantly like other parents. He also did some research about Kirino's hobby, and eventually became able to transcend common misconceptions about the otaku culture.
- When Yoshino becomes gung-ho about Kyousuke and Kirino's supposed "relationship", it's actually he who decides to trust Kyousuke (though he segues that into kicking Kyousuke out of the house so he can prove worthy of that trust by passing his entrance exams).
Daisuke: "...but don't get me wrong, I didn't do this for your sake."
- Even pointed out in the DVD Commentary by juxtaposing footage of him and Siscalypse's tsundere character. The commentators are disturbed. Fumihiko Tachiki seemed to be having fun with this in Daisuke's second commentary appearance, putting on a vaguely effeminate tsundere voice during some of his "moments".
- Clearly It Runs in the Family. Just ask his children.
Voiced by: Akeno WatanabeKyousuke and Kirino's mother and the force binding the family together. She happens to know about Kirino's hobby and Kyousuke's Porn Stash.
- The Plan: In volume 10. At first Kirino and Kyousuke thought they were being separated because the parents, specifically Yoshino, thought they were getting into Brother-Sister Incest. But it turns out she wanted him out so he really could study for his exams, since she saw how much the sibling's relationship with each other had improved drastically, and that would help motivate him to study hard.
- Reasonable Authority Figure: She doesn't seem shocked when Kyousuke tells her he knew about Kirino's secret hobby. She also doesn't make a big deal about him having porn either, but likes to poke fun at him for it.
- Troll: Look at that face. Look at that smug face!
Voiced by: Junji MajimaKyousuke 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.
Voiced by: Mariya IseA 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. She actually ends up with Makabe, however.
- 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.
- Insult Backfire: In episode 13 of season 1, Kuroneko tries to ridicule Sena's love for homoerotic games. Sena instead takes it as a compliment, and freaks everyone out. It's only after she tells them about a dream she had of Makabe getting gang-raped by the male members of the club that she realizes that she went too far.
- 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
