Mugen Kakusei

About this title

Monsters known as Calamities have invaded Earth, and humanity fights back using powerful abilities. High schooler Kouya Kamigami is considered useless because he was born without a skill in a world where everyone’s strength is measured and ranked. But everything changes when a near-death experience awakens Mugen, the most powerful Calamity in history, within him. Thanks to this, Kouya gains a powerful skill, but Mugen remains inside him, waiting for a chance to steal his body for himself. Can Kouya become the savior he’s always dreamed of, or will Mugen succeed in bringing about humanity’s destruction? (Source: WEBTOON)
