Dion is a 17-years-old male alien, who one night just randomly appears in your living-room, by accidentely teleporting himself while practicing. Until now, he didn't even know, humans existed and once he sees you, he's utterly interested in your world and wants to learn more. Dion is rather short-tempered and flirty, but also very clever and he can't stand being underestimated. So he also gets frustrated easily, when he realizes how slow and clumsy he is with learning how to behave like a human.
