Gennosuke Miura is a male supporting character from the light novel and anime series Oreimo, serving as the president of his high school’s Game Research Club and an eccentric lover of two-dimensional heroines.
Name: Gennosuke Miura
Gender: Male
Height: 179 cm
Weight: 58 kg
His exact age is unknown, but he is repeatedly described as having a noticeably mature, older-looking face.
Due to multiple instances of repeating school years, he has held the position of club president for at least two years.
Gennosuke Miura first appears in volume 4 of Oreimo.
He plays an important role as the president of the Game Research Club that Kyosuke Kosaka and his friends later become involved with.
Before Kyosuke and the others formally visit the Game Research Club, they have no real acquaintance with him inside the school.
However, Miura has already met Kyosuke once before at a midnight game release event in Akihabara, an encounter that leaves Miura with a strong liking for Kyosuke.
Kyosuke generally refers to him simply as “President.”
From that point on, Miura becomes a recurring adult-like presence around the club’s activities and game development.
Miura is a hardcore fan of two-dimensional beautiful girls and erotic games, and he makes no attempt to hide it.
He casually plays adult games even on the street or in the classroom, showing almost no concern for public perception or social norms.
Because of this extreme attitude, his junior Masaki Makabe describes him as a “bizarre eccentric” and a “pervert.”
Miura himself does not seem bothered by these labels and instead leans into the image of an oddball otaku.
His game development style tends to produce titles that are somewhat “bad games” or “kusoge” in terms of quality and balance.
Rather than being ashamed of this, he shows a strange pride in it, almost celebrating the rough, broken charm of his own creations.
Miura has repeated school years multiple times, contributing to his long tenure as club president and his older aura compared with ordinary students.
His face is frequently noted as being rather aged for a high school student, adding to his slightly “mysterious age” vibe.
Gennosuke Miura serves as the president of the high school Game Research Club.
Under his leadership, the club focuses on creating games, especially those featuring two-dimensional heroines.
He fills the clubroom with numerous figures and a large collection of adult games.
The atmosphere of the room is more like a hardcore otaku den than a typical school club space.
The equipment, game development tools, software, and specialist books found in the clubroom are not funded by the school.
Instead, Miura pays for them out of his own pocket, using money he earns from part-time jobs.
Despite his eccentric behavior, his dedication to game development and to the club is genuine.
This mix of irresponsibility in public manners and responsibility in funding and running the club is one of his defining contradictions.
Kyosuke Kosaka
Miura meets Kyosuke Kosaka for the first time when Kyosuke participates in a late-night game sales event in Akihabara at the request of his sister, Kirino Kosaka.
The events of that night leave a strong positive impression on Miura, and he becomes very fond of Kyosuke afterward.
When Kyosuke later visits the Game Research Club, Miura already remembers him and treats him warmly.
Their relationship is based on a shared interest in games, especially those involving two-dimensional heroines.
Other Club Members and Peers
Miura’s junior, Masaki Makabe, openly calls him things like “bizarre eccentric” and “pervert,” reflecting how extreme Miura’s behavior looks even within an otaku-oriented club.
Despite this, Miura remains club president and is clearly respected enough to retain leadership, suggesting his skills and passion for games offset his social oddities.
He functions as both a mentor figure and a cautionary example of “where extreme otaku life can lead,” giving the story a mix of comedy and satire.
His presence emphasizes the contrast between more socially balanced characters and full-blown obsessive fans.
Miura has an unemployed younger sister.
According to Miura, her appearance is such that he likens her to “Younger Sister Toguro,” referencing a muscular, intimidating female figure.
This description implies that she is a large, imposing woman with a somewhat fearsome presence.
Although she does not actively appear in the main storyline, this offhand remark helps flesh out Miura’s background and sense of humor.
Gennosuke Miura’s image and episodes are not based on a single real person.
Instead, he is a composite character created from several sources known to the author.
These sources include a webmaster of a personal news site who appears even within the story itself.
They also include a person the author encountered while doing research and some characters from manga works.
By blending traits from internet culture figures, real-life otaku, and fictional personalities, the creators constructed Miura as a concentrated parody of extreme game and moe enthusiasts.
This makes him both exaggerated and strangely believable for fans familiar with otaku subculture.
In the anime adaptation of Oreimo, Gennosuke Miura is voiced by Tsuyoshi Inoue.
His vocal performance emphasizes Miura’s slightly worn-out, older-sounding tone and his over-the-top enthusiasm for two-dimensional girls and games.
