Aileen finds out that Claude's aide, Keith Eigrid, has been selling demons. Keith tells Aileen about the reason why and reminisces about their past. Now that Aileen knows his true feelings, she decides to cooperate with Keith to prevent Claude from despairing about humanity and turning into a demon. At the same time, Cédric and Lilia visits the demon lord's castle to tell Claude Keith's secret?!
Because he exposed his 
powers as a demon lord,
،ولأنّه كشف عن قواه بصفته ملك شياطين
So kam ans Licht, dass er der Teufel ist.
Como reveló sus poderes,
Como reveló sus poderes,
Sa nature de démon ainsi révélée,
Per colpa di quell'episodio, 
dove ha mostrato i poteri di Re Demone,
Por expor seus poderes
de lorde demônio,
Так и вскрылось, что он Князь Тьмы.
