Character Name: Coil Lenn
Extent of what Zenitsu can pick up: Anything! Go for it. Coil is mute, sneaky, and super repressed on the emotions/emoting front, so I'm always down for anything that helps communication with him or gets past his stupid walls.
Notes for anything I should have Zenitsu pick up on: Coil is human, but is a necromancer and also has a small piece of a necromantic "demigod" inside of him, if that's something that might be picked up. He also has some very big emotions under the shuttered appearance he puts on, so have fun with that. Also, feel free to understand more of what Coil wants to say than most people do, because he tends to vent a lot of that through subtle things like the way he breathes and shifts his weight.
Anything else: Coil's permissions/abilities post and his app if it helps!
