The world after the Demon King was killed. There are Shuras who can even kill the Demon King. A swordsman from another world who can find a way to kill the opponent at a glance, a spearman with super speed who even abandons the sound, an adventurer who can manipulate the legendary weapon with three arms at the same time, an almighty word magician who can achieve everything with a word, an angel assassin who is unknowable but in charge of instant death... Shuras of all races and abilities have created a new fire of struggle in pursuit of the glory of the "real hero". All are the strongest, all are heroes, and only one is a hero. The fierce battle to determine the "real thing" has now begun.
