Back Away Slowly

This article follows the canon of CIU, which deviates greatly (for Treble in Tokyo) or even minorly (other fanons) from canon. No one else is obligated to follow the SV canon.

Jriev are a creature which are only present in the Pastel Gems' Treble in Tokyo (SV)


It was thought only humans could become Jriev. This thinking evolved into the theory that Jriev were born from heavy and burdening emotions from humans. It has now been solved that even gems can "birth" or become Jriev.


Jriev are normally all black with white features such as white eyes, fangs, beaks, or claws. Most take the form of an animal but have also been seen in humanoid form before turning into a true Jriev.


Newborn Jriev are usually more human-esque and tend to be a lighter grey rather than black. Sometimes, human features such as hair and its colour or eyes and its colour can be seen rather than white.


True Jriev are always animal shapen and are black unless they have white features. Unlike Newborns, these True Jriev tend to have stiff, matted fur, and can sometimes seem to be dirty and ravenous.


There are many Jriev families and species and each one has its different traits.

  • Human: Can speak but are so torn by emotions that they usually don't.
  • Cat: Lazy, tired, lonesome.
  • Dog: Lonely.
  • Wolf: Anger driven, seeking revenge, causing terror.
  • Insect: Flock together, destroy crops or cover windows/ doors.
  • Giraffe/ Elephant: Live in outskirts, don't normally terrorize.
  • Lion: Sometimes lazy, sometimes go to human land.
  • Penguin: Awkward, rather lazy, sometimes annoying.
