After the downfall of the Demon King, a new era dawns where a cohort of demigods possess the power to vanquish him. They include a fencer with a remarkable aptitude for spotting weaknesses, a lancer so fleet-footed they can break the sound barrier, a pyrotechnic wyvern assassin armed with three legendary weapons, a wizard with the power to manifest thoughts into reality, and an angelic hitman who offers swift and irreversible elimination. Fuelled by the ambition to be named the "One True Hero," these champions engage in epic battles against intimidating opponents and create their own disputes. The clash to crown the most supreme among them commences.
