Read Doujinshi The concept of Tsukasa Kadoya-sensei's Schale online in English. Also known as Blue Archive x Kamen Rider Decade: Schale no Kadoya Tsukasa-sensei Gainen, The Concept of Schale of Tsukasa Kadoya Sensei, Story of Tsukasa Kadoya Sensei in Schale, and シャーレの門矢士先生概念.

In this crossover fan comic, Tsukasa Kadoya from Kamen Rider Decade steps into the world of Blue Archive as the adult figure at Schale. Kivotos is already a city full of armed students, strange incidents, school rivalries, and emotional baggage, but Tsukasa brings a very different kind of presence: blunt, unpredictable, and somehow exactly where trouble is about to happen.

The appeal comes from watching Kamen Rider spectacle collide with Blue Archive’s mix of comedy, chaos, and surprisingly heartfelt character moments. Tsukasa’s role is not simply to fight; he pushes students to face their fears, protects them when danger closes in, and turns familiar Blue Archive situations into sharp, energetic crossover drama.

This series may appeal to readers who enjoy tokusatsu crossovers, Blue Archive fan stories, and action comedy with strong character moments.
