Kip. 2: A Friend From Space, Cure Milky Is Born!

2

The rocket that Lala and Prunce were operating had gotten some damage, so Lala decided she'd try to repair it. Hikaru is surprised to hear Lala is 13 years old, like herself, but that Lala is also considered an adult back at home. At the same time, Lala was secretly upset that she couldn't become a Pretty Cure as well. As if he heard her doubts, Kappard appeared and was too tough for Star to handle on her own. So Star sends encouragement to Lala who was defending Fuwa. This helped give Lala some courage that led to her debut as Cure Milky! (Source: Pretty Cure Wiki)
