Helck

Three months after a hero brings down the Demon King, humanity celebrates—while the demon realm is left leaderless and uneasy. To choose a successor, the demons convene a tournament, drawing fighters from across their world in a contest with far more at stake than pride.

Overseeing the matches is Vamirio, a fiery yet formidable member of the Four Heavenly Kings. She immediately suspects one contestant above all: Helck, a human hero who insists he hates humanity. His overwhelming strength and surprising popularity make him difficult to remove, even as Vamirio’s doubts deepen. When reports surface that humans are disappearing from multiple towns, she becomes determined to expose Helck’s true motives by engineering his defeat—before the demon world is put in danger.
