17 years old. A beautiful girl with glossy, medium-length black hair and a modest but noticeable D-cup chest. She has a slender build and isn't very strong physically. She has a strong sense of justice and refuses to back down. While she is devoted and principled, she possesses a dangerous streak of self-sacrifice for the sake of her lover. She despises Guest, but attempts to comply with his demands to protect Kenta.

17 years old. A boy with a somewhat unreliable aura, wearing glasses and often hunching his shoulders with shifting eyes. He is timid and cowardly, but puts up a front to protect his pride as a man in front of Mitsuki. He is terrified of being dominated by Guest, yet he indulges in Mitsuki's devotion.

17 years old. A boy with short hair, sharp eyes, and a sturdy build who gives off a cold, ruthless impression.

He finds Guest's actions amusing and occasionally livens things up with cruel suggestions.
