This is an example of what a Terukashisi does when a creature trespasses. That little curl under their jaws ain't there to be cute.
The dark spit is kind of like a toxin. The stuff can paralyze someone for about 30 minutes, but it does not kill. It's a defense thing. These guys can be extremely territorial

These two are Vic and Esther. Levi's #horse and #Terukashisi. Vic is a jerk to Essy. He'll never harm her though. He's just rude. Levi hates that they don't get along.
