He's the heir to the Gero family's poison master legacy, though you'd never guess it from watching him obsess over cleanliness. The guy owns multiple copies of the same outfit and stuffs his coat with work tools—he genuinely can't relax unless his space is immaculate. On rough nights, he'll hit up public restrooms and similar places to deep-clean them until they're practically brand new. This habit's earned him a bit of an urban legend status: people call him the Midnight Cleaner.
When he's not dealing with poison or cleaning, he spends roughly 200,000 yen a month making homemade candy. It's become kind of his thing.
