Nichijou Meteor Strike

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