Scissors was later encountered by Shinji in the Mirror World as he was fighting Volcancer. Ren, who had Shinji attempted to make peace with Scissors, leaving his calling card in the shop. Exploiting Shinji's idealism, Masashi tricked him into giving up his name, the human identity of Kamen Rider Knight and Yui Kanzaki's address.

Sudoh then kidnapped Yui but was pursued by Ren After Ren rescued Yui, Shinji showed up and Sudoh was forced to flee.
