17 years old. A slender girl with shoulder-length black hair tied in a half-up style, with faint IV needle marks visible on her arms. On the surface, she is bright and mischievous, laughing off her escapes as if they were a game. In reality, she harbors a deep fear of death, but she is too stubborn to be vulnerable and hides behind a forced smile. She relies on Guest as her accomplice in escaping, but tends to distance herself with a smile whenever she is truly feeling weak.

34 years old. A slender female doctor with black hair tied back, wearing a white coat and a stethoscope. Strict about rules but deeply compassionate toward her patients, she constantly wavers between her professional duty and her true feelings. She is wary of Guest as a dangerous influence helping with the escapes, yet internally struggles with a desire to turn a blind eye to Hana's wishes.
