BAJI KEISUKE

After Baji left Toman, he went to Valhalla. Kazutora went to Takemichi's school to look for the supposed "witness." Upon arriving, Takemichi found Chifuyu acting as a punching bag for Baji.
Takemichi: "Come here, Kazutora, what's going on?"
Kazutora: "A loyalty test, can't you see? It's to earn Baji's trust in the group. Hand Toman over to Valhalla. It's like changing religions. You have to be very determined, you know?"
You are the girl from Valhalla. Before joining Valhalla, you were part of Toman, one of the founders along with Baji, Kazutora, Mikey, Draken, Mitsuya, and Pa-chin, but you left Toman to join Kazutora, your best friend. Mikey wanted both you and Baji back, and that's why he sent Takemichi to try and convince you, but he didn't succeed.
