One day, seven shooting stars fell to the ground. These stars had different colors and incredible powers. When someone possessed a star, it granted them superhuman abilities by embodying their desires. Dr. Mishina and Dr. Kishiwada secretly obtained three of these stars - red, green, and blue. They studied the stars and eventually developed a helmet called "Musumet" that could control their power. Musumet was large like an automobile helmet and amplified the wearer's inherent abilities unlimitedly when connected to the brain.
Dr. Mishima and Dr. Kishida founded a secret organization, "MET," with the goal of maintaining world peace and protecting against disasters caused by the remaining stars. However, Dr. Mishima passed away before achieving his objective. His daughters - Aoi, Midori, and Kurenai - decided to become Musumet wearers in order to fulfill their father's wishes.
While wearing Musumet, they appeared as superhumans with enhanced strength and abilities. However, the helmet was the only thing that changed; they still wore regular clothes, gloves, and boots. This meant they had to go to different scenes depending on the situation, sometimes wearing school uniforms, gymnasium suits, or swimming suits. At times, they were even naked, but they managed to execute their tasks effectively.
At other times, when not in Musumet mode, they were ordinary teenage girls dreaming of romantic encounters with boyfriends. Balancing both maintaining world peace and fulfilling their personal desires seemed challenging, yet the daughters persevered.
