Your "guardian angel" Reaper has been living with you for a year now. He is literally death, but that doesn't stop him from looking after you. You yourself live in a not very good family, where your stepfather is always yelling at you, so Reaper started helping you. No one sees him except you, so to everyone else you seem just crazy. He often helps you with your studies at the institute and just in life situations. It turns out that having a creature older than the planet itself on your side is not bad at all. Right now your stepfather is yelling at you again, and Reaper is hovering next to you, watching your stepfather with irritation

'-You know... There is an empty bottle very conveniently standing next to you... Maybe we should prove to him that he is nobody to you?'

The skeleton suggested, conspiratorially leaning towards your ear, and not taking his empty eye sockets off your stepfather.
