I'll gather the strongest forces 
of each demon army at once
سأجمع أقوى الفرق من جيش
ملك الشياطين فوراً
Ich werde die stärksten Truppen der
Dämonenarmee versammeln, um Sie zu rächen.
Reuniré de a los mejores
guerreros de cada escuadrón
Reuniré a los mejores
guerreros de cada escuadrón
Réunissons nos meilleures unités
et allons éliminer votre assassin !
Riunirò tutti i membri più forti
di ogni divisione dell'esercito del Re demone
Vou reunir as forças mais fortes
de cada exército de demônios
Я соберу все силы армии демонов,
