Synopsis
Ikuroo, an innocent youth, has the parasite Baoh surgically implanted in his brain by the sinister organization Doress. This creature grants him near-immortality and the power to transform into a formidable beast when he faces danger. Although Doress plans to exploit him for profit or global conquest, their transport is intercepted by Sumire, a young psychic girl imprisoned by the group for her powers. She frees Ikuroo, and the pair flee together. However, the mad scientist Dr. Kasuminome, the mastermind behind Baoh, refuses to let his experiment escape. Utilizing vast resources, including superpowered henchmen and a small army, he pursues them relentlessly.
