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.
And after you use forbidden 
magical law just once,
وعند استعمالك قانون السحر
،المحظور ولو لمرّة
Und selbst ein einziger Einsatz
von verbotenem Magierecht
Y cuando la usas,
aunque sea una sola vez,
Quiconque utilise un article interdit,
même une seule fois,
Basta utilizzare il Codice Magico Proibito 
una volta soltanto,
E depois de ter usado direito
mágico proibido apenas uma vez,
Достаточно раз обратиться
к запретному Закону о паранормальном,
