R-15 (novel series)

R-15 is a Japanese light novel series written by Hiroyuki Fushimi and illustrated by Takuya Fujima. The story revolves around Taketo Akutagawa, a prodigy artist with erotic tendencies, who enrolls in a prestigious academy, Private Sugonoura Academy, for geniuses. However, the school has a hidden secret: it's filled with students who excel in various specialized fields but also have their own particular quirks and eccentricities.

The "R-15" in the title refers to the rating usually associated with media containing suggestive themes and situations suitable for mature teenagers (typically 15 years and older). The series is known for its humorous and often absurd situations, blending elements of slice-of-life, comedy, and ecchi genres.

The light novels have been adapted into an anime television series produced by AIC and directed by Takuya Satō, which aired in Japan in 2011. The anime generally follows the plot of the novels, showcasing Taketo's interactions with his classmates and his attempts to navigate the unique challenges and opportunities presented by the academy. The series explores the nature of genius and the humorous aspects of adolescence within an unconventional educational setting.
