The Demon King's army continues to fight against humans. Ike, the leader of the Undying Brigade, is the grandson of the great magician Romberg. Despite being respected, Ike hides his human identity, fearing the disaster it would cause should it be known.
and so he revolutionized 
the Demon Lord's army.
.وهكذا أحدث ثورة في جيش سيّد الشياطين
und nach diesem Prinzip reformierte
er auch seine Dämonenarmee.
ce qui a permis
de réformer l’armée royale.
e assim ele revolucionou o
exército do Lorde Demônio.
и этот подход кардинально изменил армию.
