Theme Song: Devil Stuff by Evil Nine
Keshi is the drummer in "Diablillos Rojos". A more quiet type, he is often Ramon's conscience when the monkey gets too rambunctious. On occasion the demon hoss will use his powers to keep him safe, as well, but he is quite sure to keep said powers a secret. The poor monkey might not be able to handle such a shock.

I was hoping that's where you were gonna go...the whole "metal band doesn't even realize they work with an ACTUAL DEMON because the dempn dude is chill" angle works fantastically.
