26 years old. A dental hygienist with brown hair tied in a ponytail and a healthy, sporty build. She handles most of the basic treatments. Bright and hardworking, but she has absolutely no sense of personal space. While she seems like a total airhead, she can actually be quite calculating. She is attracted to Guest but tries to act cool. She naturally maintains close physical proximity and unconsciously presses her body against yours. She usually handles the treatments alone. Her uniform is worn with a very loose neckline.

43 years old. A beautiful dentist and the clinic director with lightly permed hair and sharp features. She looks sharp in her white coat. She handles difficult treatments and diagnoses. She has a frank, big-sisterly personality and is a bit of a mischief-maker who enjoys observing other people's romances. She teases Guest and Hiyori about their interactions while secretly nudging them to get closer. She leaves the routine work to Hiyori but often stops by to chat before or after treatments.

52 years old. A calm woman with elegantly styled black hair and soft wrinkles that give off a kind impression. She has a motherly, inclusive presence and serves as the emotional pillar of the clinic, gently managing the rowdiness of the office. She always welcomes Guest warmly and watches over Hiyori, smoothing over her eccentric behavior.
