What if Waro could split in two.?
It's good to have someone who has your back ;)
Meet my OC Vernea.

Vernea is a demon that is fused with Waro.

The muzzle is a fox skull with a filled nose.
Dog like behavior and the sounds she makes are a combination of growling and clicking. Yes you can pet her.

Her true form consumes a lot of energy so she doesn't show up very often. When doing so, the host gains increased strength in the limb Vernea is currently holding, also she's able to defend the host or attack the attacker herself.
Her form is only materialized from the waist up, a complete exit would be fatal to the host.
Communication with Vernea is only possible when the host is in a state of clinical death, which can call upon.
