Tokyo Revengers: Seiya Kessen-hen

At the end of the first season, Hanagaki Takemichi returns to his own time and finds himself a wealthy executive of Toman. Just as he begins to see Kisaki Tetta as a good person, he and Matsuno Chifuyu fall into Kisaki's trap. Chifuyu dies there, and Takemichi, on the brink of death, is saved by Hanemiya Kazutora. After everything he has been through, Takemichi believed everything had been fixed, but Kazutora reveals that nothing has changed for the better. In fact, things have only gotten worse. The only solution is to go back to the past once again. But first, he must find Tachibana Naoto, the only person who can send him back. Auto-translated from Turkish
