Synopsis
R-15 follows Taketo Akutagawa, a young prodigious writer with a specific niche: erotica.
He finds himself enrolled in Inspiration Academy, a unique school designed for students with extraordinary talents.
The story centers around Taketo's daily life as he navigates the challenges of his gifted peers and the social stigmas associated with his work.
He strives to perfect his craft and achieve recognition, facing humorous and potentially awkward situations along the way.
Ultimately, R-15 is about Taketo's journey to become the world's greatest writer, while dealing with the eccentricities of his school and his own somewhat controversial artistic choices.
