Seishun Kijinden! Nishio Gakuen

What if the most iconic oddballs from NisiOisiN's sprawling literary universe suddenly shared a homeroom? That is the delightfully chaotic premise behind this celebratory crossover: Koyomi Araragi, the reluctant vampire-adjacent fixer from *Monogatari*; Ii, the sharp-tongued protagonist of the *Zaregoto* series, and his formidable associate, Jun "Humanity's Strongest" Aikawa; alongside Kyouko Okitegami, the brilliant private detective whose memory is wiped clean every time she sleeps—all find themselves as classmates in a single, surreal academy. The stage is set for a collision of supernatural mysteries, razor-sharp dialogue, and eccentric personalities, but rather than solving deadly conspiracies or battling aberrations, they are thrust into the mundane—and absurd—hijinks of school life. This 4-panel gag manga was commissioned to commemorate the 15th anniversary of author NisiOisiN's groundbreaking career, which famously launched in 2002 when his debut novel, *Zaregoto: The Kubikiri Cycle*, earned the prestigious Mephisto Prize. True to form, the title itself is a clever wordplay: "240 Gakuen" employs a numeric pun where "240" is pronounced as "Nishio," rendering the full name as "Youth Oddball Story! Nisio Academy." Inside these pages, the high-stakes drama and intricate mysteries of their source material are playfully subverted. Classroom antics replace grim investigations, supernatural afflictions become the butt of jokes, and the residents of this academy navigate everyday chaos with the same verbose wit and philosophical tangents that define their creator's style. It is a loving, self-aware tribute that reimagines these legendary characters not as heroes or detectives, but as overthinking, bickering, and surprisingly endearing students.
