Parasyte: Part 1

The alien invasion begins.

A teenage boy becomes an unwilling host when an alien parasite invades his body, fusing with his arm before he can stop it. Trapped between human compassion and inhuman hunger, he must navigate a fragile coexistence with a creature that craves only bloodshed. As more parasites infiltrate humanity, the boy discovers that survival means embracing the monster within—and accepting that the line between man and beast has irreversibly blurred.
