Nodoka decides to let Asumi stay with her so that she can be close to Rate, managing to convince her parents Asumi is Rate's owner who has traveled to Japan from abroad. Nodoka helps Asumi to understand Earth customs as she has only been alive for one day and finds everything new and strange. The next day Nodoka injures herself protecting Asumi; when Asumi asks her why she goes to so much trouble to help out, Nodoka tells her that her experiences from being ill changed her and she wanted to repay the kindness she was given. Meanwhile, Daruizen creates a MegaByogen from a Flower spirit, and Guaiwaru reveals it can be powered up using the crystals he took from Batetemoda's possession which they call Mega Parts. Daruizen then discovers they can harvest more parts from the powered up MegaByogen. The girls arrive and transform to defeat the MegaByogen, with Cure Earth protecting Cure Grace from Daruizen. After Cure Earth purifies the MegaByogen, Asumi tells Nodoka that she hopes her own experiences change her in the same way Nodoka's did.
