Cain finally gets to participate in a magic class, this time to learn summon magic... and he ends up summoning the Prince of Darkness. Meanwhile, signs of a monster onslaught have been observed in the Forest of Monsters.
Why has a human summoned me, 
the Prince of Darkness?
لماذا استدعاني بشريّ، وأنا أمير الظّلام؟
Comment de vulgaires humains
ont-ils pu m’invoquer,
Perché un umano ha evocato me,
il Principe dell'Oscurità?
Por que um humano invocou
a mim, o Rei Demônio?
Что за человек посмел 
тревожить покой повелителя демонов?
