So one day there's a massive meteor shower, right? And one of these meteors lands in the room of a guy named Koichi. And it says it can grant wishes, but when Koichi asks for a pet, the meteor goes nuts, and then it becomes his pet, but he's more like a destructive, annoying roommate, and then another meteor shows up, then... Oh, just read it. Especially if you like Pop Team Epic. (Source: Mangamo)
