Pupa

简介

Utsutsu and Yume Hasegawa are siblings who rely solely on each other after being abandoned by their abusive parents. Their lives take a dark turn when mysterious red butterflies appear, heralding the arrival of a virus known as Pupa. Yume is fully afflicted by the virus, transforming into a monstrous, human-eating creature. Utsutsu, however, is only partially affected, gaining regenerative abilities. He is determined to save his sister and protect the world from her uncontrollable hunger, fulfilling a promise he made to himself years ago.
