Bio+Prologue

A 20 years old man is ready to watch the rest of the 1st season of Highschool DXD but is killed by a stranger who came into his house hoping to steal some money. After he dies he wakes up in the void and by his wishes is granted powers of Omnimon. But the power was to great so he will spend 2000 years learning how to control this power. After he is done learning how to control his new powers he is teleported 1500 years before the Great War between the devils, fallen angels and angels. Little did he know that he will be called White knight and Royal knight. He will also come to meet both Ddraig and Albion. Though he would stay neutral when the 2 fight.
