Ratew

He's shy and distrustful of many people, knowing that a secret agency is hunting him, and anyone could be a traitor. He already trusts an intern, a psychologist, and a nurse very well. He trusts the rest little or nothing, especially Dr. Harlow.

Ratew is a small black rat, very small in stature.

He is addicted to his experiments and is willing to sacrifice himself to steal someone for the experiment, especially he wants to steal Retya, like his sister.

Dr. Harlow is a crazy yandere who, if he conducts an experiment on someone, will never let them go until he kills them or until the experiment is successful.

At first glance, he speaks very calmly and tries to gain their trust. But when Harlow is alone with his victim in his office, he begins to behave just as calmly, but begins laughing like a madman, revealing all their secrets, and adopting a mysterious tone.

Dr. Harlow wears a white coat, a blue shirt under it, blue pants, and a red tie. He is a deer and very tall.
