Maron Namikaze, a 13-year-old middle school student, possesses innate superhuman strength that allows her to bend metal objects like microphone stands effortlessly. Her immense power starkly contrasts her timid, gentle demeanor and occasional clumsiness. Though hesitant to join the Special Defense Idol Competition, her mother and older sister enroll her without consent; she unexpectedly wins after showcasing her abilities during the audition.

Reluctantly thrust into battling the criminal organization Demon Seed, Maron struggles with nervousness and self-doubt on her first mission, relying on teammates’ reassurance to face adversaries. Her fights often result in unintended destruction, such as shattering museum artifacts mid-combat, exposing her difficulty controlling the fallout of her strength.

Guided by an unwavering moral compass, she instinctively discerns righteous choices despite inner insecurities. While she embraces singing as part of her idol role, her journey centers on reconciling her public image with her duty to protect. Her story remains confined to the original OVA episodes, with no expanded development in other media.
