Эп. 34: Аи плачет во время битвы, из-за чего её страх усиливает Джикочу.

34

During a battle against Ira and Marmo, Ai suddenly starts crying, which causes Ira and Marmo to feel a surge of energy. As the girls struggle to cheer Ai up, Mana and Rikka hear from their respectives mother about how they were as babies. Having heard how much her mother appreciated having her, Rikka helps Mana look after a crying Ai during the night. The next day, as the girls take Ai to the park, Ira creates a Motorbike Jikochu, which grows stronger with Ai's frightened cries. Coming to understand Ai's fear, Rikka manages to calm her down, weakening the Jikochu and allowing the PreCures to defeat it. As the girls wonder how Ai's cries resulted in the Jikochu growing stronger, they are contacted by Ange. (Source: Wikipedia)
