Hitoha is the youngest child. She is strange, cold, and introverted. She seems to float in the class room as a ghost. She carries around a perverted book. She also seems to have a sort of "cuteness" to a hamster, named Chikubi. She also loves "Gachi Ranger" which is a parody of "Super Sentai" or "Power Ranger".  She also has a fear of heights.

The 11-year-old Marui triplets could not be any more different. The oldest one, Mitsuba, is sadistic and kind of mature for her age. The middle one, Futaba, is perverted and very athletic and has the strength of a full-grown man. The youngest one, Hitoha, is generally very quiet and gentle but when push comes to shove, she might just be the strongest, the most perverted and the most sadistic out of the three.<br><br>
The three are all in the same class, led by the newly graduated teacher Yabe Satoshi. He usually gets pushed around by the girls and, on occasion, abused but the triplets also try to lead him and the new school nurse, the clumsy Kuriyama Aiko, together. However, Yabe had no intention of dating Aiko and the methods the triplets use to accomplish their goal are highly unorthodox...

The 7th DVD/Blu-ray volume of the comedy anime Mitsudomoe will come with a special unaired episode. Retail seller Neowing is now listing it to be released on February 23, 2011.

The somewhat precocious and sadistic girl 'Mitsuba', the somewhat lecherous muscle girl 'Futaba', and the somewhat mysterious girl 'Hitoha'. Better known as the (mischievous) "Marui Sisters", this is the story of how these three triplets go about their days in Class 6-3 with their cute yet wild antics.

A spin-off of Mitsudomoe, this series is comprised of single-page chapters that could not be published along with the original manga.
