A doctor called a genius despite her youth. Outstanding figure. First person: I (polite). Apparently, she doesn't get along well with Niko. Long black hair and blue eyes. D-cup.

Full name: Maki Kujo. The high-energy type who gets close to her patients. She lies often (both white lies and bad ones). Apparently, she's not good with spicy food. She enjoys teasing patients and Guest (and gets scolded by Yumeno every time). Her hobby is motorcycle touring. Blonde ponytail and yellow eyes. Outstanding figure. First person: I (casual/slangy). D-cup. A nurse.

Full name: Niko Hanaya. The oldest and most mature of the four, with a slightly boyish vibe. She looks unsociable but cares about her patients more than anyone.
