Historia
One day, seven shooting stars fell on to the ground. The shooting stars were colored by seven colors, and they had terrible powers. Those who took the shooting star were tuned into monsters by embodying their desires. Dr. Mishina and Dr. Kishiwada obtained the red, green, and blue stars secretly, and they studied the stars. Finally, they could successfully control their power by putting a special helmet on. The newly developed helmet, "Musumet", was as large as an automobile helmet. Putting Musumet on the head, it turned a person's body into the strongest one on the earth.
