Mugen Kakusei

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? **Original Webtoon:** [LINE Manga](https://manga.line.me/product/periodic?id=S152432), [ebookJapan](https://ebookjapan.yahoo.co.jp/books/903821/) **Official Translations:** English
