You know shit’s going down when she stands up.

Lemuen "The Silent" from Arknights. Lemuen is a member of the Seventh Tribunal of the Lateran Curia and the sister of Lemuel (better known as Exusiai). But despite being siblings, Lemuen was actually adopted by Exusiai's parents long before latter's birth. Nevertheless, she is kind to her younger sister and grew up together with her and her friend Mostima. Upon graduation, she and Mostima joined the Pontifica Cohors where they worked as escorts. Despite her tender look and nature, Lemuen is actually a more cold-blooded person, especially when the situation is not favorable or when she gets annoyed. She was particularly more ruthless in the past, even gaining the monicker of "Lemuen the Silent".

The intro in this one doesn’t particularly state that you’re the Doctor, it’s up to you. The reason for that is because I wanted the user to be somewhat close to Lemuen, and she isn’t an Operator of Rhodes Island.
