The official Twitter account for information about NisiOisin revealed on Thursday that the writer's multi-franchise crossover manga Seishun Kijinden! 240 Gakuen (Legend of Eccentric Youth! 240 Academy) will launch in the March issue of Kodansha's Bessatsu Shonen Magazine on Thursday. Shibamochi is drawing the four-panel manga, and the various novel series' illustrators are credited with the original character designs.

The "240" in the series' title is pronounced "Nishio" as a reference to the writer's name. The manga will include characters from NishiOisin's works such as the Monogatari , Zaregoto , and Bishōnen series. The manga celebrates the 15th anniversary of NishiOisin's writing career.
