Mary

 She/Her/It? 

Mary is a spirit who is able to possess mirrors

As someone who was never able to develop her own identity, and was never able to perform expressions and emotions, Mary uses her access to mirrors to watch others and copy their expressions and emotions. However, because her presence in a mirror twists the reflection into something monstrous, she has yet to understand emotions outside of fear. When she is not going out of her way to try and emote, her face is very flat and lifeless.

Mary died when she was very young, so she has a somewhat childish worldview. Her perspective is also very tainted by the things she was taught by her oppressive family when she was alive, so she has a negative view of anything she views as "acting out."

Despite this, she's friends with Hata no Kokoro and maybe Koishi Komeiji and Flandre Scarlet as well :]
