In Hentai World as Mira Tsubakihara's Relative Novel

When Hikari transmigrated into this 2D world, reality shattered his expectations. The Shuchiin Academy, Service Club, Yukino, and Eriri simply vanished—replaced by a bewildering, treacherous existence.

Living under Mira Tsubakihara's roof, Hikari navigates an increasingly chaotic life. Kasumi, Mira's closest companion, brings her own mysteries. A silver-haired enigma resembling a Yuki-onna occupies the neighboring apartment, tending to sunflowers and hydrangeas. His class rep Chizuru and homeroom teacher Miwa Shirakawa anchor his school life, though three flirtatious gyarus incessantly badger him about hosting celebrations. Sakurajima Miyajima commands the Kendo Club with iron will, while Nanao Akane manages the Baseball Club's operations. The elegant Sakuramiya sisters dominate the Archery Club scene, and the prestigious Sekai Girls' Academy looms nearby as a constant reminder of this world's complexity. Countryside relatives Kaiseiri and Sayoko remain distant presences, while his peculiar neighbor—a self-proclaimed "self-defense force" NEET—embodies society's decay.

Peril saturates every shadow of this corrupted realm. Carelessness invites catastrophe and unspeakable horrors. Yet Hikari refuses despair: "This world overflows with filth and corruption, but I'll crush it with a single punch." —The Pure Love Battle God, Nakamura Hikari.
