This movie starts with Saze X playing basketball. Suddenly, a lightning bolt hit the earth. They walked towards it and found a boy. The boy's name is Ricky, and he thinks he has forgotten everything. On the other hand, Remy told Sazer-X that a giant monster named Mechanical Giant Bulgario had approached Earth and was destroying buildings. Sazer X still defeated the monster. But then something flashed into their eyes, and Takuto mistook it for a cosmic capsule. In fact, this is the Bosquito people that exist within Bulgaria, which Professor Horiguchi later explained.
