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.
My rage and hatred turned 
me into the Demon Lord.
.غضبي وكراهيتي حوّلاني إلى ملك الشياطين
Mein Zorn und Hass haben mich
zum Dämonenkönig gemacht.
Mi ira y mi odio me convirtieron
en el Señor Oscuro.
Mi ira y mi odio me convirtieron
en el Señor Oscuro.
La colère et la haine
m’ont transformé en roi-démon.
La rabbia e l'odio che provavo
mi tramutarono nel Re dei Demoni.
Meu rancor e ódio me
transformaram no Rei Demônio.
Мой гнев и ненависть превратили меня
в повелителя демонов.
