Ryōko Hanuki

A dental hygienist who 'gives the best gum massages'. Ryōko is close to Higuchi and Jōgasaki. She likes getting inebriated, at which point she drastically loses her sense of judgment and flirts with whomever is around. Aware of this, she is cautious about choosing who she goes drinking with. She serves as a formal love interest for the protagonist in episodes 6–8.
