Mitsuba, Futaba, and Hitoha are not your typical Japanese students. Satoshi Yabe who's a newly hired teacher will have to learn to deal with these three girls as they terroize him or it will end up getting the best of him.
Hitoha is nervous about meeting the Gachirangers' Gachi Pink at an autograph session, but ends up catching a cold on the day. She ends up going anyway, though when she does not want to be seen by Yabe, she ends up hiding under Gachi Pink's table, where she manages to thwart a guy taking upskirt photos. In order to win a relay race against the other sixth graders, Yuudai and Hitoha come up with a plan to take advantage of each runner's traits. A sweet potato salesman with an eye for telling a woman's age is put to the test when Hitoha challenges him to guess how old she is. Later, Soujirou remembers when his daughters were younger and more well behaved.
