One day, a giant monster in the shape of a bug appeared over the world… with only the "Children of the Butterfly" to fight against it.---When a swarm of giant bugs threatens to wipe out humanity, the world’s only defense is a group of humans with special abilities called Butterflies. For Maehwa Baek, Butterflies are just heroic people he sees on TV until a tragic event brings him to the scientists that created them. Soon, Maehwa must confront questions about himself that he has long avoided: why does he lose control at the sight of his own blood? And what happened during the 13 years of his life that he can’t remember?---[Original Webtoon](https://comic.naver.com/webtoon/list?titleId=749633)**Official Translations:*** English: [LINE](https://www.webtoons.com/en/fantasy/blood-of-the-butterfly/list?title_no=3162), [Tappytoon](https://www.tappytoon.com/en/comics/the-blood-of-the-butterfly)* [Chinese (Simplified) / 汉语](https://www.dongmanmanhua.cn/BOY/hudiesihao/list?title_no=1546)* [Chinese (Traditional) / 漢語](https://www.webtoons.com/zh-hant/fantasy/bloodandbutterfly/list?title_no=2222)* [French / Français](https://www.webtoons.com/fr/fantasy/sangs-et-papillons/list?title_no=2351)* [Japanese / 日本語](https://manga.line.me/product/periodic?id=Z0001370)"
