ksy (Patreon)

 Original character: Ksy

 Ksy's body is composed of waves, and it can exist simultaneously in any time and space connected to this world until it is observed. He likes to observe civilization. However, since it is a kind of mutation, there is a biological bias (brain error). He has no control over his body.

The origin of his name is an operator (Ξ) that represents an unknown in quantum mechanics.
He has no control over the body and is not stationary as a substance.

 When his emotions rise, he returns to his original form.
