Re:Hero — Starting Over As The Strongest
C48/100Web serial by LaughYeAmer
Demon King Erizen thought all Heroes were insane. For one thousand years he ruled the continent of Thalmyra while lunatic bands of Heroic Chosen Ones tried and failed to end his reign — until a random peasant girl from a back-end village manifested the Holy Sword, led a Crusade to his door, and ended his life before dying herself seconds later. As he died alongside the smiling Heroine, Erizen could not understand: why did heroes not care for their lives? What gave them such suicidal strength? When the System offers him reincarnation, he makes the only choice that makes sense — he will reincarnate not as a Demon King, but as a Hero. If even a peasant's heroism was enough strength to kill him, then this heroic Demon King vows to become nothing but the strongest.
