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.
It's the lowest level, where spirits ranked 
with a danger level of A are kept.
إنّه المستوى الأدنى، حيث تُحتجز الأرواح المصنّفة
بمستوى خطر أ
Das war im untersten Geschoss,
wo Geister der Gefahrenstufe A sitzen.
Es el nivel inferior,
donde el nivel de peligro es de A.
Es el nivel inferior,
donde el nivel de peligro es de A.
Tout en bas, un dangereux
esprit de classe A est confiné.
Si tratta del piano più basso, dove vengono tenuti
gli spiriti di pericolosità di livello A.
No nível mais baixo, onde espíritos
com nível de perigo A são mantidos.
Речь шла о низшем уровне,
о духах класса опасности А.
