Doppel ドッペル

"Doppel" (real name unknown) is a member of the M.O.N., where she acts as the team's infiltrator. Doppel's default form has the appearance of a small, petite young girl. Her skin is dark, she has very long light-colored hair and black sclera. However, this is not her real form. It's unknown what her real form looks like, but is implied to be very eldritch, being called a "faceless existence". Indeed, Doppel herself admitted that if humans were to see it, "their mind wouldn't be able to handle it".

Doppel seems to be a natural trickster, taking delight using her powers to prank people and loves seeing people freak out. It is said she often takes jokes too far. However, Doppel prefers to prank those who deserve it, such as criminals, as it is easier to avoid punishment that way.
