The carefree Tsunami is next in line to rule over the Magical Kingdom of Juraihelm. But before she is officially crowned as queen, she must restore balance to the universe that has come to favor darkness. To accomplish her goal, Tsunami gives the ordinary Sasami Kawai a magical baton that can transform her into a magical girl. She also appoints the rabbit-like creature Ryou-Ouki to aid Sasami in the battle against evil. However, Sasami refuses to become a magical girl—not because she is scared, but because she finds it too embarrassing! Meanwhile, the arrogant Ramia is plotting to overthrow Tsunami by enlisting her own magical girl—the eccentric Pixy Misa—to cause chaos and ensure that balance is never restored. As Pixy Misa terrorizes the planet with her Love-Love monsters, Sasami must learn to swallow her pride and accept her role as the universe's champion of justice, Pretty Sammy.

Saki Uno is an average 15-year-old girl with a side hustle as a member of the exceptionally unpopular idol duo Magical Twins. Despite this, she absolutely loves the time she spends with her best friend Sakuyo Mikage as she strives to become closer with her childhood crush, Sakuyo's brother Mohiro. Her peaceful life, however, unravels when she finds a yakuza-looking thug trying to enter her house. Forced to invite him inside, Saki learns that her mother used to be a demon fighting Magical Girl, and that her brutish guest is actually a mascot named Kokoro-chan looking to recruit a replacement. Dumbfounded and skeptical, Saki is hesitant accept the request until Kokoro-chan reveals that Mohiro is a target of some cute, squirrel-tailed demons. Rushing to his side, Saki's overwhelming desire to save Mohiro activates her Love Power, and a daring confession awakens her as a Magical Girl. However, because her body is not suitable for combat, Saki's transformation turns her into a muscle-bound man clad in a pretty dress. Now, as a fully-fledged Magical Girl, Saki must team up with Sakuyo to protect the love of her life from the fluffy, demonic menaces that run rampant in her world.
