A girl gets a magic girl suit jammed into her body that makes her moan during every transformation, then has to fight actual supervillains while dying of embarrassment. The comedy isn't in the transformation itself, it's in watching her try to maintain any dignity while her own body betrays her in front of people. A stupid premise executed with enough commitment that you stop questioning why this exists and just laugh at how relentlessly it commits to the bit.

Arisa's ordinary life as a sixteen-year-old high school student takes a mortifying turn when a combat suit invented by her brother gets accidentally implanted in her body. Every time she transforms, the suit makes her let out suggestive, embarrassing noises. To make matters worse, she soon finds herself pushed, much against her wishes, into fighting an evil secret society. She longs to confess her feelings to Matsumoto-senpai, the man she dreams about, but trying to do so sets off her transformation. The result is a one-episode magical girl comedy with a heavy ecchi streak.
