Bleach: The Shinigami Who Inherited Hashirama

A soul enters the world of Bleach —and awakens the legacy of Senju Hashirama. Not chakra. But life itself, reborn as reiatsu. A Wood-Style Zanpakutō that devours spiritual power. A body that regenerates faster than it can be wounded. Forests rise at a single thought. Seireitei notices an academy anomaly. The captains begin to watch. Aizen realizes this power does not belong to his plan. With each sign-in, Hashirama’s will awakens further. Life grows. Suppression becomes absolute. When the Thousand-Year Blood War reaches its end— the battlefield ascends to the Soul King Palace. There, a colossal wooden Buddha descends, and Yhwach is crushed beneath divine wood and living reiatsu. This is not Naruto in Bleach. This is the birth of the strongest Shinigami in history. — Description from novelcodex.org
