Meeting Yoh
The gang first appears at the cemetery, which is their best place during that time. Ryu destroys the tombstone of Amidamaru because he thinks that there is no curse.

Ryu attacks Yoh but is defeated by him.

Meeting with Tokageroh

At the same time, Tokageroh wants revenge on Amidamaru. The possessed Ryu breaks into the museum, and steals the Harusame, at the same time he kidnaps Oyamada Manta.

He confronts Yoh and Amidamaru, and orders Amidamaru to integrate with his master so they can fight. He tricks Amidamaru into attacking the Harusame and fights back with a technique called "Tokage-Kenpo" (Lizard Style). Tokageroh mocks Amidamaru saying that the same sword that was supposed to save him will take his life instead this time. After remembering how much Harusame was important, Amidamaru breaks the Harusame and Tokageroh is surprised. Yoh says that Tokageroh had already lost, because of Amidamaru's long-life commitment to his friend Mosuke. He tells him that he should rest in peace and move on. Tokageroh refuses and says he'll die and Amidamaru with him. Ryu's gang then attack him and say that they don't want Ryu to become a scumbag, and they'll always be friends with Ryu no matter what happens.

Having no other option. Yoh offers Tokageroh to possess him, which he does. After saying it was foolish, Tokageroh tries to kill Yoh, but realities that he can't do that and he is being lectured again on how important trust is and being alone was painful for him, and after receiving trust from Yoh he doesn't need to take revenge, because he realized that revenge wasn't something he needed in the first place
