Getting called a demon lord 
the day you transfer here, huh?
Kaum bist du hier,
schon nennt man dich Teufel.
Entonces te llamaron Rey Demonio 
en cuanto llegaste, ¿eh?
Así que te han llamado "Rey 
Demonio" nada más llegar, ¿eh?
Propulsé au rang de maître magicien
dès son premier jour !
Então você se muda pra cá e já fica
 se chamando de lorde demônio, é?
