Meatball Machine

Necroborgs are alien parasites that humans abuse as host bodies, suddenly appear in Japan. Their victims are transformed into monstrous combat robots armed to the teeth. They only have one goal: to track down and destroy other Necroborgs. Unsuspecting, the shy mechanic Yōji accidentally takes such a parasite home with him. When Yōji arrives at home one day accompanied by his beloved Sachiko, she promptly gets attacked by the parasite. Yōji desperately tries to free her from the parasite. But he literally didn't take one thing into account.
