Hiiro learns the magic spell of the Kokuu blade, a weapon which will strike an enemy from afar.  Hiiro is far too terrible a swordsman to put it to use, but Master Theo notices that he has incredible power.  Theo realizes that not only is Hiiro keeping Dagan Zot's heart in check, Dagan Zot is the only thing keeping Hiiro's heart from going out of control...
It didn't feel hot, or feel like 
your soul was being devoured, right?
لم تشعروا بحرارتها، أو أنّ أرواحكم تُلتَهم، صحيح؟
Sie waren weder heiß,
No se sentía caliente 
ni devoró sus almas, ¿verdad?
No sentisteis calor ni devoró
 vuestras almas, ¿verdad?
Votre âme est restée dans votre corps
et vous n’avez pas brûlé.
Non era calda e non avete avuto la sensazione
 che vi stesse divorando l'anima, vero?
Vocês não sentiram calor, nem como se a alma
 de vocês estivesse sendo devorada, não é?
