The Marui triplets return in an unaired bonus episode released with the seventh DVD and Blu-ray volume of Mitsudomoe. Hitoha, the youngest, is often pestered by her sister Futaba, who loves squishing her soft cheeks. Things get worse for Hitoha when a pimple shaped like a breast shows up on her cheek and brings her unwanted attention at school. Meanwhile, Mitsuba, the eldest, fiddles with sports equipment and lands herself in awkward situations. Whatever happens, life with the three sisters is never boring in this slice-of-life comedy special.
