A Day at the Marui House
Futaba goes into school with a fever, giving her a similar appearance to Hitoha and confusing Nipples, which shocks Hitoha. Hitoha ends up catching Futaba's fever, completing changing her aura. The girls convince Sojirou to let them keep a stray cat, only to find it missing the next day, which makes Hitoha upset. To cheer her up, Futaba pretends to be a cat, getting a bit too into her roleplay, before Sojirou brings in the cat himself. Later, Yabe comes around the Marui household for a home visit, but as he plays with the cat, Sojirou comes home and misinterprets it as an advance on Hitoha, leading him to get violent against him. Mitsuba wins two tickets and ends up giving them to her siblings, pretending to have other plans. However, it later turns out each ticket admits two people and Mitsuba gets left out, though Sojirou later buys an extra ticket for her.
Aired 26/09/2010EP 13 - A Day at the Marui House

Mitsudomoe
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.
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...
