銀魂 帰ってきた3年Z組銀八先生 フェニックス ファンキーモンキーティーチャーズ

[DeepL Translation - needs review] Volume 1: [A novel version of the book is now available! A disheveled white coat, eyes like dead fish. Ginghachi Sakata has a personality and appearance unbecoming of a high school teacher. His homeroom class, Gintama High School Class Z, is crowded with students of strong characters, and has turned into an amusement park of terror!　The popular comic "Gintama" extra chapter "Gintama: Gintama, 3 years Z class, Ginpachi sensei" has become a novel!
