Baoh: The Visitor

Ikuro is seventeen and wants one thing: to get Sumire back, the psychic girl he escaped with after Doress, a secret Japanese program that collects psionics, took her from him. The parasite living inside him, Baoh, keeps him alive by turning his body into a weapon, with acid-tipped claws and brute strength. Hiroyuki Yokoyama sends him against commandos and psychics, and Ikuro fights like someone who has already stopped counting what it is doing to him.
