Synopsis
The world's strongest hero — trained since childhood by a Sage, a Saint, a Swordmaster, a Magical Archer, and a War God — betrayed humanity at fifteen and defected to the Demon King's army. His reason was simple: they treated him better. Warm beds, good food, friendly maids, a kind Demon King. Compared to humanity's side, which offered severe training and constant mortal peril, this was paradise. He had no regrets. His bright, comfortable life as the world's most powerful freeloader was just beginning.
