Gero, Hikaru

下呂ヒカル

The heir to the Gero family's poison master clan. He is the type of person who owns multiple copies of the same clothes, and he carries various work tools under his coat. He does not feel at home unless his surroundings are immaculate. On nights following a bad day, he cleans public toilets and similar places until they are in better condition than when they were newly installed. Because of this, he is something of an urban legend known as the Midnight Cleaner.
Amount he spends on DIY candy per month: About 200,000 yen.
