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.
其中，拥有特殊天赋的人可以获得使用“神器”作为武器的特殊能力。傲娇的青梅竹马天谷春莲（泽子夏舞配音）、坦诚直率的知八稻穗（叶水一枝配音）、叛逆霸气的吉信木林（Yazusha Yori配音），在大山和这些可爱的女孩忙碌而惊心动魄的学术生活中结下了牢固的友谊。随着他们的能力逐渐提高，大山意识到他们似乎卷入了一场大规模的战争。
