The Kagemori clan has protected their next door neighbours, the Konnyaku family, for 400 years. Each family member is an actual ninja, including the dog. They each protect a member of the Konnyaku family. Mamoru is tasked with keeping their daughter, Yuuna, out of trouble. Unfortunately Yuuna is clumsy, absent minded and a little stupid. She's a magnet for any kind of trouble from mobsters to aliens. Mix in Mamoru's friend for the ninja village, a rival ninja, a samurai and more and you have yourself a wacky comedy from the mid 2000s.
