Season 1
A mysterious red button appears before an unlikely ensemble—Tanya Degurechaff, the 16-year-old isekai protagonist Satou Kazuma, Overlord’s Ainz Ooal Gown, and Rem and Ram—who press it out of curiosity and are transported to an unfamiliar world. With no apparent route back, they must navigate a mundane school life, forge new acquaintances, and endure a classroom packed with beloved, quirky personalities that keep every day anything but dull.
