Rekka no Honoo

Synopsis

Recca and Domon manage to defeat Fuuko and destroy the mind control orb, and they learn that Kage Houshi cannot be killed. The next day, Tokiya Mikagami confronts Recca and states that he knows of what occurred the night before, but Recca acts oblivious. Shortly after, it is revealed that Tokiya is pursuing Recca because Kage Houshi led him to believe that Recca may have connections to the men who murdered his sister when he was a child. He eventually confronts Recca in the park, and attacks him with Ensui, a sword that manipulates water. As Recca is about to be killed, Yanagi rushes in to try to stop the fight, and Tokiya is shocked upon seeing her because she looks just like his deceased sister.
