15x16 - Kamen Rider

Zanki and Todoyama come to Sabaki�s rescue after being captured by the Yamaarashi, but Zanki begins to weaken and proves unable to defeat it. Todoyama takes Zanki�s place and destroys his first giant-type Makamou. As Zanki retires, Todoyama refuses to take his name, instead wanting to make a name for himself, as Zanki dubs him Todoroki, the Roaring Oni.
