Plot

Kyōsuke Kōsaka, a normal 17-year-old high school student living in Chiba,[1] has not gotten along with his younger sister Kirino in years. For longer than he can remember, Kirino has ignored his comings and goings and looked at him with spurning eyes. It seemed as if the relationship between Kyōsuke and his sister, now fourteen, would continue this way forever. One day however, Kyōsuke finds a DVD case of a magical girl anime which had fallen in his house's entrance way. To Kyōsuke's surprise, he finds a hidden adult game inside the case and he soon learns that both the DVD and the game belong to Kirino. That night, Kirino brings Kyōsuke to her room and reveals herself to be an otaku with an extensive collection of moe anime and younger sister-themed adult games she has been collecting in secret. Kyōsuke quickly becomes Kirino's confidant for her secret hobby.

Characters

Kyōsuke Kōsaka (高坂 京介 Kōsaka Kyōsuke?)
Voiced by: Yuichi Nakamura
Kyōsuke is the 17-year-old main character of Oreimo. He has a distant relationship with his sister, feeling that this will never change. However, this suddenly changes when he finds one of her adult games and learns that she is an otaku. Through this, he tries to be a supportive older brother while realizing he himself knew very little about his sister, such as being almost flawless at school to working as a model. Later on, he takes up more of his role as an older brother to her, and appears to be able to tell what she is thinking or really meaning to say despite her tsundere personality. Despite this, she is generally the dominant person in their relationship, with Kyōsuke being shown to be openly intimidated by her, only standing up to her in truly serious situations. Kyōsuke prefers to have a relatively peaceful and simple life despite the fact that the drama Kirino brings makes his life anything but peaceful.
Kirino Kōsaka (高坂 桐乃 Kōsaka Kirino?)
Voiced by: Ayana Taketatsu
Kirino is Kyōsuke's 14-year-old younger sister. She is mature for her age with a cold, tsundere-like personality. She has a strong "little sister" fetish and owns many adult games with older brother and little sister themes; she got a job modeling to pay for her hobby. Despite her interests, she states she does not know why she started liking it, though it is suggested that she has a brother complex and is using the games as a surrogate to this. She often denies such feelings and believes the 2D and 3D worlds should be kept separate. Nevertheless, she is shown to be very frustrated when her brother is with or shows interest in other girls, such as Manami, who she accuses as being "all over" Kyōsuke. Likewise, she frequently forces Kyōsuke to spend time with her, whether it is playing games or taking her out, but denies that she actually enjoys the time they spend together. She goes as far as hitting him after he complains that she is ordering him around as if he was her boyfriend, and goes out of her way to sabotage his time with another girl. Despite stating she only likes her adult games because of their cuteness, she shows a perverted side to herself when playing. She uses the screen name Kiririn when with her otaku friends.
Manami Tamura (田村 麻奈実 Tamura Manami?)
Voiced by: Satomi Satō
Manami is Kyōsuke's childhood friend. She wears glasses and is described as 'plain'. She has a crush on Kyōsuke and blushes to his compliments. Due to the time they spend together, the people around them assume they are dating. According to Kyōsuke, her speech patterns resemble that of a grandmother.
Saori Makishima (槇島 沙織 Makishima Saori?) / Saori Vageena (沙織・バジーナ Saori Bajīna?)
Voiced by: Hitomi Nabatame
Saori is the leader of the "Anime Girls Unite!" group on the Internet, whom Kirino meets in a meet-up. She wears very thick glasses (shown as swirls) and speaks with an exaggerated tone. She is a fan of Gundam and is also a collector of their model kits. Saori is an aristocrat from a wealthy family, and speaks with a highly formal voice outside of meeting with her friends. She is tall and usually has to get cosplay tailor made. As Kyōsuke says, Saori is drastically different from how she communicates through the Internet and through phone or speaking with her in person, to which she seemingly switches to a refined and sophisticated persona. According to Kyōsuke in the light novels, she is dressed as a typical otaku from television but has the body of a supermodel. Despite her cheery attitude, Saori is quite lonely, living by herself, and has always feared that one day her true friends (Kirino, Kyōsuke, and Ruri) would leave her in a similar way that her older sister (who got married and moved away) left her.
Ruri Gokō (五更 瑠璃 Gokō Ruri?) / Kuroneko (黒猫?, lit. Black Cat)
Voiced by: Kana Hanazawa
Ruri is another otaku girl who lives near Kirino and often wears gothic lolita clothing based on a character from her favorite anime, even during hot weather, and will sometimes add cat ears and a tail. Due to both of their tsundere-type personalities, she constantly clashes with Kirino when it comes to anything. However, Kuroneko does care for Kirino. Unlike Kirino who likes little sister-themed games, Kuroneko enjoys teen-centered fantasy anime. She often mentions "dark magic", claiming that she has it, usually to Kirino or to Kyōsuke. She is noted to have a very high vocabulary, to where Kirino commented she needed to use a dictionary to translate her novel. Kuroneko actually wears red contact lenses to make her bluish eyes seem red. Kuroneko also has younger sisters, whom she dearly cares for. At school, Kuroneko wears normal clothes and at home, takes care of her younger sisters. In the anime, she later refers to Kyōsuke as "nii-sama" due to her wishing to have an older brother and suggesting to annoy Kirino.
Ayase Aragaki (新垣 あやせ Aragaki Ayase?)
Voiced by: Saori Hayami
Ayase is Kirino's friend and classmate who works as a model alongside her and is also her best friend. Ayase is a friendly, nice, and refined lady, but becomes agitated and somewhat violent at the thought that she is being lied to, which she hates above all else. She tends to believe what she sees on the news. Therefore, she disapproves of anime and manga, calling it a disgusting hobby, especially adult games, due to the media portrayal that otaku will eventually become criminals.
Kanako Kurusu (来栖 加奈子 Kurusu Kanako?)
Voiced by: Yukari Tamura
Kanako is Kirino and Ayase's fellow friend, classmate and model, who has sometimes swaps between a cute personality to a bratty one. She enters a lot of idol auditions and is a talented singer, able to memorize a song after hearing it only once. She is unaware of Kirino's hobby and generally finds anime childish and otaku disgusting, though she is on one occasion tricked into cosplaying as Kirino's favorite anime character, Meruru, for a contest.
Daisuke Kōsaka (高坂 大介 Kōsaka Daisuke?)
Voiced by: Fumihiko Tachiki
He is Kirino and Kyōsuke's domineering father. He is a high ranking officer in the police and has a no nonsense policy at home. He does not like the fact that Kirino is a model, but allows her to do so if she does well in school. He is severely against otaku, believing them to be a waste of a life, so when he finds out Kirino is one, he initially orders her to throw away everything otaku-related in her room. After being given a verbal beat-down by his son, he allows her to keep everything except for the hentai, and even that he reluctantly allows Kyōsuke to keep after the latter claims ownership of it. It is shown he truly does care for Kirino despite his gruff exterior, as he owns every article and picture of all her accomplishments.
