Bico, a magical tools master who attended the Magic Law School with Muhyo, suddenly appears at the Bureau one day. Bico asks Muhyo to come to Magic Prison No. 18, a prison where very powerful spirits are sealed. A talisman that had been used to seal the bottom level, where the most dangerous spirits are kept, has been ripped off its door... and Bico feels responsible as the one who had made the talisman. Muhyo agrees on the condition that Bico will owe him one later, and they set off for the island that houses the magic prison.
Which is why they've been using 
talismans to temporarily seal spirits,
لذا كانوا يستعملون طلاسم لختم
الأرواح بشكل موقت
Deshalb werden Bannsticker benutzt,
um Geister provisorisch zu versiegeln.
Por eso usamos talismanes
o sellos espirituales temporales,
Por eso usamos talismanes
o sellos espirituales temporales,
Bref, pour régler le problème,
on les a scellés temporairement.
E questo è il motivo per cui abbiamo utilizzato
dei talismani per sigillarli temporaneamente,
Por isso que eles estão usando talismãs
para selar espíritos temporariamente,
Потому мы и создаём талисманы,
чтобы временно запечатывать духов.
