Kamen Rider - Season 14 Episode 29 The Two Chalices

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.
