The new "slapstick" story will follow Komugi-chan and her rivals as they balance their everyday lives as students, idols, and magical girls "with laughter and tears."
Komugi Yoshida is a somewhat clumsy second-year middle school student whose strength lies in her energetic spirit. She works as an idol alongside Kokona Saionji, her classmate and close friend, as well as Tsubasa Kisaragi, an idol who wears male clothing. However, unlike Kokona, whose popularity is skyrocketing, and Tsubasa, with her charm in masculine outfits, Komugi only gets low-tier gigs like performing at the local shopping district. Still, Komugi holds onto her "dream" as she lives her double life as an idol and a middle school girl.
One day, a mysterious injured creature named Usa-P appears before Komugi. She tends to Usa-P's wounds, and in gratitude for her kindness, Usa-P asks if she wants to become a Legendary Girl who can wield magical powers.
Reluctantly becoming a Legendary Girl, Komugi battles strange masked figures who suddenly start appearing! As a newly designated Magical Nurse, she fights against more waves of masked enemies. Meanwhile, a Magical Maid, a Magical Sister, and others also emerge, turning the conflict into a three-way battle!? Can Komugi handle juggling the three roles of middle school girl, idol, and Magical Nurse? And what awaits her in these fights and her "dream"...?!
