La Belle Fille Masquée Poitrine

Yuko Murakami is a normal schoolgirl who stops at a quiet shrine and makes a clumsy mistake that changes her life. After she damages a bell and accidentally lands it on a turtle, the shrine spirit rewards her with the power to transform into a local superheroine modeled on an ancient deity. By shouting "Cosmo Magic! Métamorphose!!" she becomes the Masked Beauty Poitrine and takes on petty crooks, strange creatures, and everyday threats to her neighborhood. The show keeps things light, mixing slapstick moments and action set pieces as Yuko balances school, family, and secret duties without any big, single finale spoilers.

Released in 1990, the series is the eleventh entry in Toei's Fushigi Comedy Series, created by Shotaro Ishinomori and Yoshio Urasawa. It stays faithful to the live action, kid-friendly tokusatsu tradition that Toei had been cultivating, though specific directors or episode credits vary across the run.

The series didn't pick up major mainstream awards, and it wasn't aimed at the kinds of festivals that hand out those prizes. Instead, it found its place as light evening entertainment for families and kids, and it has been remembered more as a niche favorite than an awards contender.

Fans and tokusatsu enthusiasts often point to the show when they talk about how serious superhero tropes can be played for laughs. The transformation call and the turtle-granting-power gag are often cited in retrospectives, and Poitrine sits alongside other quirky Toei heroes as an example of how the genre could be family-friendly while still delivering action.

Critical and fan reception tends to praise the program's humor and upbeat tone, and the available ratings suggest a small but positive audience response, with a 8.0/10 vote average on some fan sites. Themes include responsibility in a community, sibling and school life, and the contrast between ordinary routines and sudden heroism. It's easy to watch, frequently silly, and aimed squarely at viewers who want adventure with a smile.
