At long last, Yumiella and her companions reach the Demon Lord's castle, but his power is so great that she's the only one who stands a chance against him. Then the Demon Lord tells them the true story of his connection to Valschein's royal family.
If you stay here, you could fall 
under the Demon Lord's control.
.إن بقيت هنا، قد تخضع لسيطرة ملك الشياطين
Wenn du hierbleibst, gewinnt der Dämonenkönig
vielleicht die Kontrolle über dich.
Si te quedaras aquí,
podría controlarte el Señor Oscuro.
Si te quedases aquí,
podría controlarte el Señor Oscuro.
Le roi-démon risque de te contrôler,
si tu restes ici.
quindi, se resti qui, corri il rischio che
il Re dei Demoni prenda il tuo controllo.
Se ficar aqui, pode acabar sendo
controlado pelo Rei Demônio.
Повелитель демонов
может тобой овладеть.
