Shougo Kitsukawa

He defeats Siegfried and almost drowns him and leaves so Akisame and Sakaki can fish him out. Berserker is told by Loki to lead his "New Eight Fists" once the latter proclaims his betrayal of Ragnarok during the attack on Shinpaku Alliance. However once he got close enough, he quickly defeated them all, including Loki, and claims that he only came to Loki just to get closer to attack. He is subsequently challenged by Hermit, who became angry that Berserker took out Loki when he was going to do it. At the beginning of the battle, Berserker's foresight is unable to overcome Hermit's ability to land attacks, forcing him to use odd techniques to counter him.

When Hermit gets around those attacks as well, Berserker finally goes into Berserker Mode and overwhelms Hermit. Ultimately, he is defeated by Hermit, who twists one of his arms and unleashes a multitude of devastating attacks. Berserker is unwilling to admit defeat and attempts to continue on, despite his injuries, but is dissuaded by Kenichi, who tells him that one should not be ashamed of defeat because one learns more from it. Berserker then stops trying to fight, warns Kenichi about Odin, and is finished off by Odin. Berserker much later would seemingly join Yomi, as a silhouette of him is shown standing amongst three people whom Kensei picked out for disciple testing.

After the death of Silcardo Jenazad, Ogata Isshinsai is seen discussing the events with his disciples while looking highly amused. Kokorone Rimi vividly remembers her past encounter with the Demon God Fist, but Berserker remains in the shadows like before, impassively chewing and blowing bubble gum like he did during the Ragnarok Saga. He makes his first formal appearance standing behind his former leader, Asamiya Ryuuto, when the Yomi members are summoned to headquarters by Kushinada Mikumo. Someone throws shurikens at him and the other disciples but he catches it with his mouth and blows a bubble around it while wondering what fights the others have been through so far.
