Magical tools masters normally can't use magical tools, but Roji realizes that Rio used one to protect Bico. Meanwhile, Muhyo has collapsed after exhausting his ren, leaving him in a dangerous condition of mental numbness... the exact moment Rio has been waiting for.

Então eu fui no trabalho da Bico
Тогда я пошёл в мастерскую Бико
