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.
Aw! Your guard's up and 
strong as ever, you cruel boy!
!دفاعك شديد كعادتك أيّها الصبي القاسي
Mensch, du bist auch immer
auf der Hut, du Frechdachs.
¡Siempre estás en guardia, niño malo!
¡Siempre estás en guardia, niño malo!
Toujours aussi sur la défensive,
vilain garçon !
Eddai! Mai una volta che abbassi la guardia, cattivone!
Ai! Você sempre esteve de
guarda alta, garoto malvado!
Блин! Ты никого к себе не подпускаешь,
грубый мальчишка!
