[Mayonnaise] Kana is the Smallest Girl in the School and a Sexual Crime Prevention Officer [=CBS=]

Kana may be the smallest girl in her school, but she takes her self-appointed duty as 'sexual crime prevention officer' deadly seriously — offering up her tiny, flat-chested body to her classmates in the school toilet so that no other girl has to be taken. Joined by a twintailed friend who insists their grim service makes them heroes, she endures relentless public use, tears and drool spilling as the boys show her small frame no mercy, each rough nakadashi framed as one more crime prevented. A darkly ironic soushuuhen of twisted heroism, where the tiniest body in school carries the heaviest burden of all.
