Helck

In the world of demons, a tournament is held to choose the next ruler after the previous Demon Lord was defeated by a human hero. The strongest contender is Helck, a human hero who claims to hate his own kind and vows to destroy them. However, Vermilio, one of the four Heavenly Kings who is in charge of the tournament, is suspicious of Helck's true intentions and decides to investigate. With a smile, Helck says, "Let's destroy the humans," but is he telling the truth? The fate of the demon world rests on Vermilio's shoulders as she uncovers the truth behind Helck's sinister smile.
