Summary
Keisuke falls due to his injury. Chifuyu wonders what have Tetta Kisaki done, but Tetta states he haven't done anything. Takemichi and Chifuyu then realize its the wound from Kazutora and its much more serious than Keisuke stated. Takashi tells another member to call an ambulance. Tetta guesses that Kazutora is indeed crazy and had brought Keisuke to Valhalla, so that he can finish him off himself. As Manjiro stands up, Takemichi realizes that Tetta is trying to provoke Manjiro into attacking Kazutora. Manjiro reveals he though of killing Kazutora the moment he got out of juvie, however Keisuke managed to convince him to not do it and that Kazutora wanted to make Manjiro happy and to make things make sense for him, he had to make Manjiro his enemy. As Manjiro steps down, he says the fight is over. Shuji tells him its not something he can decide, but in that instant, Manjiro kicks and knocks out Shuji. Shocked by his overwhelming strength, most of Valhalla members run away.

Manjiro then approaches Kazutora, who tells Manjiro that one of them must die. In an instant, Manjiro punches Kazutora and starts beating him up. As he proceeds to beat him, Takemichi recalls Ken's words from the future and realizes that he isn't changing anything. While being beaten, Kazutora recalls earlier conversation with Shuji, who reveals reveals that Keisuke is an enemy. Thinking that Keisuke will abandon him too, Kazutora sneaks behind Keisuke while Takemichi holds him and stabs him in the back. Kazutora then recalls when he killed Manjiro's brother and how he ended up blaming Manjiro and wanting to kill him, but Keisuke told him to not say such things and that he will be with him until the end. Kazutora realizes that Keisuke was indeed always with him and he ended up destroying the most important thing to him, and accepts his death, waiting to join Keisuke in the afterlife. Keisuke then manages to stand up, yelling Manjiro's name, who then stops and turns to Keisuke. Keisuke thanks him for getting mad for him. Keisuke then walks past Manjiro and tells Kazutora that he won't die, so he must not worry. Saying that he won't die by his hands, Keisuke takes out a knife and stabs himself.

Chifuyu and Takemichi go to Keisuke, who in his final moments, tells Takemichi that Tetta is the enemy. He tells him that after the fight with Moebius, when Pah-chin stabbed Nobutaka Osanai, Tetta asked Manjiro to let him be the 3rd Division Captain in exchange of getting Pah-chin out of jail. He tried to solve it himself, but wasn't able to. However as he dies by his own hands, Manjiro won't have a reason to kill Kazutora. Seeing Shinichiro, Keisuke tells Takemichi that in a way, he is like him and tells him that he is leaving Manjiro and Toman to him. Keisuke then says he would like a yakisoba to split with Chifuyu, who tells him he will go buy one. As Keisuke thanks him, he takes his last breath and dies in Chifuyu's hands.

As Chifuyu's cry resonates, Manjiro continues to pummel Kazutora, adamant about killing him. Chifuyu acknowledges that he knew Keisuke hadn't betrayed them and had been fighting alone, but he couldn't save or protect him. Amidst his tears and despair, Takemichi reflects on Keisuke's words, which entrusted Manjiro and the future of Toman to him. Determined, Takemichi steps between Manjiro and Kazutora, who threatens to kill him too if he doesn't move. Ignoring the warning, Manjiro delivers a punch to Takemichi, urging him not to speak for Keisuke. In response, Takemichi insists that Keisuke sacrificed himself for both Manjiro and Kazutora. He took his own life not only to absolve Kazutora of guilt but also to implore Manjiro to forgive him.As Takemichi removes his jacket, a charm falls to the ground. Manjiro picks it up, inquiring about its origin. Takemichi reveals that he found it during their final meeting. The charm triggers a realization in Manjiro as he recognizes it, recalling how they had created Toman together.
