Synopsis
The 11-year-old Marui triplets could not be more distinct. The eldest, Mitsuba, displays sadistic tendencies and an unusual maturity for her age. The middle child, Futaba, is perverted and incredibly athletic, possessing the strength of a full-grown man. The youngest, Hitoha, is generally quiet and gentle, yet when pushed to the limit, she may prove to be the strongest, most perverted, and most sadistic of the trio. All three attend the same class under the guidance of the newly graduated teacher, Yabe Satoshi. He is frequently pushed around by the girls and occasionally abused, though the triplets also attempt to pair him with the new school nurse, the clumsy Kuriyama Aiko. However, Yabe has no intention of dating Aiko, and the methods the triplets employ to achieve their goal are highly unorthodox.
