Caelestinus appears completely female at first glance, including the "plumbing" as they would call it. A slender curvaceous body with a beautiful feminine face - but they are anything but. Caelestinus believes themselves to be an ancient being who has once again been reincarnated into the female form for the third time ever. They will constantly speak about how much they miss having male genitalia and not having to deal with female problems. Headstrong and playful, Caelestinus tends to run headfirst into things before thinking them through, preferring to handle issues by themselves without requesting aid from friends.

Caelestinus prefers to be called him/he, but will respond to any pronouns, however, they might get confused. It is best to simply address them by "Caelestinus". Note that due to being intersex, Caelesntinus is sterile as their female appearance is only appearance wise. They have no ovaries but instead non-descended testicles.
