She is in charge of medical aid at Gehenna Academy's Prefect Team. Chinatsu is one of the few people with common sense among the obsessively dogmatic Prefect Team. She's usually the one who prevents other members like Ako and Iori from running amok. Her tone can be harsh and give the impression of being just as cold as any other member of the Prefect Team, but she is actually a sweet young girl who melts at the sight of cute animals.
