Kato serves as a Public Safety Devil Hunter attached to Tokyo's Second Division, armed with a pact that lets him rot an enemy from within. His career ends abruptly during Reze's raid on a training compound, where his ambush fails to stop her and he is caught in a fatal blast.
One eye is gone from Kato's face, and he carries the look of someone past his prime. Otherwise he cuts an unremarkable figure, usually turned out in the regulation attire issued to Public Safety hunters.
The story never explores what kind of man he is, leaving his disposition a blank.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....
Kato appears during the assault Reze launches on the Anti-Devil Second Division's training grounds. He and Tanabe move first to bring her down, calling on Kato's pact with the Mold Devil. That contract works by biting into his own hand for blood and then aiming at a victim, which makes mold erupt within their organs and trigger internal hemorrhaging. It harms only the living, and while regeneration cannot clear the growth, cutting away the tainted flesh can. The mold takes root in Reze's heart and her gut, yet she counters by tearing off her own head and flinging it into the building to regrow elsewhere. Her abandoned body charges the two hunters and detonates, ending Kato's life.
