It's been made into a novel! An anime! And, something no one expected, it's now been made into a vertical manga! With his sloppy white coat and dead fish-like eyes, Sakata Ginpachi has a personality and appearance that are hardly befitting of a high school teacher. His homeroom class, Class 3-Z of Gintama High School, is crammed with students with equally strong personalities, turning it into a terrifying amusement park. Is there really a future for such a problematic class?! The spin-off of the hugely popular comic and anime "Gintama" has landed on Jump Toon for the first time! (Source: JumpToon, translated)
