Exil is a strange, hooded girl who appears to not be from the same universe as everyone in Deltacreep. In fact, she so happened to randomly teleport in while running away from someone or something. She is accompanied by an Akumu-like creature named Tamashi, who mainly fights for her due to the lack of "hands" (yes, she has no arms or hands). When fused with Tamashi, she gains two giant shadow hands on her back, and in dire need open a literal portal to either another universe or to Hell itself. How she dodges attacks is by sharing magic: if an attack boost is needed, she will share half of her magic to Tamashi, while also being shared magic in return. The same goes with dodging, except it goes from Tamashi -> Exil. She's mainly speed based, and wishes to get a fight done so then she doesn't need to do anything else. Tamashi acts as a shield caster and can turn into a sword/spear thing of sorts as well.

In this AU, however, her main goal is to just seal the fountain, considering Kris and Susie might as well not do it at all. She has been the source of multiple destructions of universes, note that.

So...yeah. There's that.
