After the incident in the park, Nodoka took Rate home and convinces her parents to keep her for a while, to which they hesitantly agree. At another world, the Byogens were aware about the appearance of Cure Grace and how it will ruin their plans on infecting the world. The next day, Nodoka goes to her first day at school, and the animals come with her in the hope of finding partners for Pegitan and Nyatoran. Nodoka discovers she is in the same class as Chiyu Sawaizumi and Hinata Hiramitsu, two girls she met the previous day. After school, Rate sensed another MegaByogen attack as she calls out and draws Rabirin and Pegitan back to her (Rabirin had broken up her partnership with Nodoka earlier in the day and left with Pegitan trying to follow her). Hoping to make up for her lost time, Nodoka wants to help protect the world as a Pretty Cure. Rabirin realizes she was wrong about Nodoka and the two reconcile. Nodoka transforms into Cure Grace and defeats the MegaByogen, freeing the Tree Spirit trapped in the monster.
