"The repeated invasion from the other world has started to change this world's structure. The "Magic Power" which did not originally exist has emerged and became the new axis of the world. Upon the birth of the new powers, came the evildoers and the creatures from the other world who are attracted to the power.

Meanwhile, there are young girls who use the their own magic power to transform themselves into magnificent warriors. They stand in the battlefield as allies of justice to protect people from the danger and monsters. Those girl are called 『Mahou Senshi』(Magical Warrior).

On the other side, there exist those who would get their hand on the "Magic Power" to experiment, understand, or use it to conquer the world. One of those men is Amatsuka, who is a talented and ambitious man as well as one of the researchers of 『Imperio』, the company that quickly realized the potential of magic power. One day, when Ametsuka was frustrating about his position, he met a man named 『Metzer Heinkel』 who became can make his ambition into reality.

Thus, Amatsuka begins his fight to realize his dream of dominating the world using magic. However, standing in his way are the lovely warriors of the combined power of magic and science in the beautiful outfit『Symphonic Knights』. Amatsuka begins to strategize against the innocent girls to corrupt them with his new powers and monster minions."
