Hitoha is nervous about meeting the Gachirangers' Gachi Pink at an autograph session, but ends up catching a cold on the day.

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.
