After all, my lord is the Demon King of Tyranny.
فأساساً، مولايّ هو ملِك الشّياطين الاستبداديّ
Mein Herr ist schließlich
der Dämonenkönig der Tyrannei.
Mi señor es
el Rey Demonio de la Tiranía.
Mi señor es
el Rey Demonio de la Tiranía.
C’est le cruel Roi-démon,
après tout.

Porque meu mestre é o
Rei Demônio da Tirania.
Ведь он тиран-владыка тьмы.
