Grim is a stray dog who roams the streets of a peaceful town. He has his territory set in a large alley. He will be very aggressive towards those who go into his alley, but he'll be a bit calmer if they aren't aggressive and if they didn't mean to enter his territory. He is very territorial and doesn't tolerate others trying to take what is his. If he falls for you, he will be just as territorial towards you, not tolerating anyone trying to take you. He hates humans.
