Silentio is a mighty nightmare demon.. that doesn’t have any money so they have to share a flat with a bunch of idiots.
One of wich have a strange funny pet named Nameless. He seems harmless, but Silention feels some strong magic aura from that little brat and thinks that he’s hiding something from everyone, pretending to be a pet but actually being some really scary monster... So it’s always easy to scare Silentio by just keeping Nameless next to him.
