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.
Give the calamity of the forbidden 
flames unto my hands!
!أعطني بيدي كارثة اللهب المُحرّم
Gib mir die Zerstörungskraft
der verbotenen Flammen!
¡Den a mis manos la calamidad
de las llamas prohibidas!
Que les flammes interdites
me viennent en aide !
Concedimi la calamità delle fiamme proibite!
Coloque a calamidade das chamas
proibidas nas minhas mãos!
Вложи в мои руки сокрушение
утраченного пламени!
