Name/Moniker: Jericho Kersey (biological name), the Unhappy Girl (creature name)
Sex: Female
Species: Undead human (non-corporeal)
Appearance: Composed of a black substance with the consistency and translucency of fog. Its eyes are white and luminscent. It appears to have clawed digits, but it is unknown if they are actually claws. The creature has approximately two rows of sharpened teeth in both its bottom and top gums. It also has subtle digitigrade legs, in which the feet also appear clawed. It has poor posture and a laggard and unsteady gait.
The creature maintains features it had in its life as well, such as: its hair, which is brown and cut at chest-length, and its clothing, a brown sweater vest, white button-up shirt, and jeans. It does not wear shoes. When in its disguise form, these features seem to vanish.
Behavior: Tends to secrete an unidentifiable, non-Newtonian, black fluid that fluctuates between the consistency of ink and tar. It is prone to smearing this substance on walls, floors, and occasionally ceilings. On some occasions, it has written threatening messages in this fluid, although these threats appear to be flippant in nature.
If a piano is available, it will sometimes attempt to play it. It does not appear to know how to do so, however, and will usually press keys in a random order until it can compose something musically coherent. In general, it seems to have a penchant for music. It enjoys listening to others sing, and may try to sing along at intervals.
The creature has an inclination towards untidiness and clutter, and will toss things such as garbage, rotten food, and (on one occasion) plant clippings in disarray. There are two recorded instances of it purposely knocking a glass or otherwise fragile item off from a high place and letting it shatter.
Origin: To not be listed. Current reported origin stories only alleged, inconsistent, and subject to change.
