Shooting Starlets Musumet(2004)

Shooting Starlets Musumet is a magical girl series about three sisters who inherit a secret mission to save the world. When seven shooting stars crash to Earth, scientists discover they can harness their power through special helmets called Musumet, which grant superhuman strength and abilities. After their parents' deaths, sisters Aoi, Midori, and Kurenai take over the fight for global peace, protecting Earth from the remaining four stars while juggling typical teenage concerns—school, romance, and rivalry with the wealthy, snobbish Saotome sisters. The three heroines must balance their secret identities and newfound powers against the pressures of ordinary life, all while keeping their mission hidden from the world.
