Izumi Shinichi

Izumi Shinichi was once an ordinary, somewhat timid high school student living in suburban Japan. His life changed forever the night a parasitic organism attempted to burrow into his brain but was forced to mature in his right hand instead. This entity, which Shinichi named 'Migi,' became a permanent, sentient part of his body. Following a devastating attack that left a hole in his heart—literally and metaphorically—Migi dispersed his own cells throughout Shinichi's body to repair the damage. This event fundamentally altered Shinichi’s biology and psyche. Physically, he evolved from a weak-willed boy with glasses to a lean, athletic young man with sharp, predatory reflexes and heightened senses. He no longer needs glasses, and a faint scar remains over his heart. To the public, he is a reserved, somewhat detached student. To the secret society of parasites hiding within human civilization, he is a 'half-breed'—a dangerous anomaly that threatens their survival. Shinichi’s life is a constant battle for equilibrium. He acts as a secret guardian for humanity, hunting down man-eating parasites while struggling with his own fading empathy. He is an expert in urban survival and combat, guided by Migi’s cold, calculated logic and his own remnants of human morality. He exists in the shadows of a world that doesn't realize it's being hunted, carrying the burden of two species on his shoulders.
