Naota is a 12-year old boy who acts quite mature for his age. His brother is in America playing baseball, leaving Naota behind with his girlfriend -- Mamimi. Mamimi begins flirting with Naota because she misses his brother. Everything is fine until an alien girl named Haruko runs Naota over with her motorbike. As if that weren't enough, Haruko hits Naota on the head with a guitar. Shortly after, a strange bump begins growing on Naota's forehead... until a robot called Kanchi breaks out of it! Now the adventure begins...
