.لهزيمة ملك الشياطين والزواج من إدوين أيضًا
Ich will, dass du sowohl
den Dämonenkönig besiegst
Para que derrota al Señor Oscuro
y para que se case con Edwin.
Para que venza al Señor Oscuro
y para que se case con Edwin.
Que ce soit vaincre le roi-démon
ou épouser Edwin,
Sia nello sconfiggere il Re dei Demoni
sia nello sposare Edwin.
Tanto em derrotar o Rei Demônio,
quanto em se casar com o Edwin.
И повелителя демонов убить,
и за Эдвина выйти.
