So there's this guy, right? His name's, like, Masato or something. He's got bags the size of suitcases under his eyes. He wakes up one day to find that cloud/sheep things have gone and kidnapped everybody. He also meets this boy/girl/sheep named Dori that's all sunshine and rainbows and stuff. They go around looking for people that haven't been taken by the sheep, with Masato beating sheep along the way with the power of beauty-sleep or something because of a promise he made to his dying mother. How's that for weird?
