Bleach: From the moment I was invited by Squad Zero (BFM)

Even after graduating at the top of Shin’ō Academy, he joins the quiet Kidō Corps instead of becoming a fighter. For ten years, he lives like a simple clerk while secretly mixing his old magic with Kidō. Then Central 46 finally notices him. Yamamoto summons Kaito with an offer he cannot refuse: join the Zero Division, the Royal Guard of the Soul King. His peaceful life is over. Noble families, dangerous secrets, the King’s Key, and a war with a powerful enemy are waiting for him. Kaito only wanted to live quietly. But in Soul Society, staying hidden may no longer be an option.” I spent two lives becoming strong.
