He's the heart of this story—the oldest member of the Inuyashiki family, though his appearance works against him. At 58, he looks significantly older, which earned him nothing but contempt from those around him. His own family dismissed and mistreated him regularly. Really, his only companion was his dog Hanako, who actually seemed to care.
Things were bleak. A cancer diagnosis landed, and death looked inevitable. Then a meteor crashed down and killed him—except it didn't. Instead, it turned him into a cyborg with abilities he never asked for. That's when something shifted in him. Rather than use his newfound power for revenge or personal gain, he made a conscious choice to help people. He's said that staying human meant using what he had to save others, not destroy them. Fans often note this decision defines his character more than the cyborg powers ever could.
