Risu

Risu eventually discovers that he possesses the rare power of Curse and excitedly tells his best friend Aikawa. Unknown to him, Aikawa is the unwilling alter ego of the CrossEyes Boss, who murders Risu and attempts to take the ability. Risu's Curse activates at death as an avenging specter too powerful for the Boss to handle. Years later, Risu is resurrected and fused with that specter, which will not let him rest until his killer is dead.
