Azumi, the Serpent Undead, finds Aikawa and fights him with the help of the Tortoise Undead. Garren and Blade show up to help as Chalice staggers away. Having lost his memory, Aikawa encounters Ryo Mikami, a takoyaki vendor that looks like him. After the vendor shakes off his initial shock, Mikami proposes that the two trade identities in order to avoid a life he feels is too difficult. Posing as Aikawa, Mikami is found by Amane and taken back to Kenzaki and the others. Meanwhile, Aikawa begins to blend into Mikami's life.

The Serpent Undead continues to search for Aikawa. Mikami learns about Aikawa's identity, and tries to get his life back. Mikami's girlfriend, Michi, learns the truth about Mikami and Aikawa, but is happier with Aikawa. Michi and Mikami's fathers have a vendor contest which is interrupted by the Serpent Undead. Aikawa regains his memory and seals her. The Tortoise Undead intercepts Blade and Garren on their way to the battle. Aikawa arrives and gives Garren the Queen card. Garren then transforms into Jack form and seals the Undead.
