Miasma is a very cunning type of person. She is not quite a manipulative individual, but she does enjoy to play with peoples' minds. Seeing people confused by her language, or her actions excite her beyond belief. She is able to evade with ease physically and mentally. In particular with how she is partially a spirit (not entirely since she still has her human heart!). Miasma is a very cynical person given her experiences, along with her own personality. She fails to trust anyone who attempts to befriend her. Her perception of the world is pessimistic, with little to no hope for the human race.

Given that Miasma is part bat, she has excellent hearing. It's controlled with her hat to allow her to not be damaged by concentrated sound.
