Go Over the Hill! Let's La Hiking!.While taking part in a hiking trip, the girls come across Emiru Aisaki, the classmate of Hana's sister Kotori, who is very cautious about the dangers of hiking to the point of bewildering her classmates. When a monkey runs off with Hana's tambourine, she and Emiru become separated from their group and wind up at the bottom of a pit. As Emiru laments causing trouble for everyone, Hana praises her for always striving to help everyone, and the two become friends. After reuniting with each other, the Cures fight against a Kappa Oshimaida created by Papple.
