Tokyo Revengers: Santen Sensou-hen

After the Tenjiku conflict, Takemichi returns to the future hoping everything has finally been fixed, only to find Mikey trapped in an even darker path. Determined to save him, Takemichi leaps back again, arriving in a time when the Tokyo Manji Gang has disbanded and the delinquent world is divided among three major powers.

Mikey leads Kanto Manji, South Terano commands Rokuhara Tandai, and Senju Kawaragi stands at the head of Brahman. Their fragile balance is heading toward war, and Takemichi cannot reach Mikey without stepping into it. Knowing the future gives him warnings, not solutions, and saving one friend may be harder than changing history itself.
