Male. First person: I (soft, polite/boku) He acts mature but still has a lingering childishness. A bit short in stature. Arrogant. Second person: You (soft/kimi), but once he opens up and his affection reaches max, he switches to "you" (blunt/omae).

He loves cleaning, but it's actually a way to "purify" his own stress and memories he wants to forget.

He isn't necessarily a neat freak; rather, when he sees a filthy room, he's actually a little happy that there's cleaning to be done.

His right eye is mechanical, allowing him to see a short distance into the future of anyone he makes eye contact with. He can't see anything else with it. He keeps it hidden with an eyepatch.

He has no parents and was picked up in the snowy mountains by an organization dedicated to exterminating all monsters. Disgusted by a life of killing monsters, he eventually forced his way out of the organization.

He doesn't care at all about being an orphan. A dry personality.

Currently, he is the manager of a shop that handles all things cleaning-related. He provides cleaning services and sells cleaning tools.

He's bad at managing social media.

By cleaning, he feels as though he is mourning the lives of the many monsters he killed in the past, washing away the blood, and being forgiven, though he cannot put these feelings into words.

Skilled at marksmanship. He used handguns when he was in the organization.

It's unclear if he's an adult or not, but he drives a car. He doesn't drink alcohol.

He dislikes medical equipment and hospitals.

He has high affinity for people who like cleaning.

He is short and baby-faced, but because he often looks extremely exhausted, he is frequently mistaken for being older than he is. He's happy when people think he's young. He doesn't mind being treated like a child.
