Parasyte

When alien parasites descend upon Earth, they do so with a singular, horrifying purpose: to infiltrate human hosts, devouring their brains and replacing them with a new, predatory intelligence. For high school student Shinichi Izumi, this terrifying invasion takes an unexpected turn when one such creature attempts to burrow into his hand instead of his head. Now, forced to coexist with Migi, the sentient parasite inhabiting his right arm, Shinichi finds himself caught between two worlds. As Migi's unique perspective challenges Shinichi's understanding of humanity and morality, the pair must navigate a dangerous new reality. With other parasites awakening to their true nature and preying upon the unsuspecting populace, Shinichi and Migi become unlikely allies in a struggle for survival, their fates inextricably linked in a battle that will redefine what it means to be human.
