Muhyo, Bico, Roji, and Bico's teacher Rio head down to the bottom level of the magic prison, a place swirling with ectoplasm. Many spirits lurk in the darkness since the talisman sealing this floor was removed. One of them, a Rain Dog, attacks the group, infecting Bico with a spirit virus. So Muhyo opens his magical law text and faces the Rain Dog...
Bico became my pupil after that.
أصبحت بيكو تلميذتي بعدها
Danach wurde Bico mein Lehrling.
Bico se hizo mi aprendiz
después de eso.
Bico se hizo mi aprendiz
después de eso.
J’ai pris Bico sous mon aile
après cet incident.
Dopo quella esperienza,
Bico divenne la mia allieva prediletta.
A Bico se tornou a minha
pupila depois disso.
С того дня Бико стала
моей воспитанницей.
