Healin' Good♡Pretty Cure

The girls take Rate to Hinata's family clinic, where Hinata's brother examines her and deduces she is suffering from a cold. He gives Rate some medicine to take and instructs Nodoka to give her plenty of rest. Everyone helps out to look after Rate, leading her to confess to Nodoka that she feels useless, to which Nodoka reassures her she isn't. However due to her illness, Rate is unable to sense when Batetemoda creates a MegaByogen and by the time the girls discover it, the monster has already managed to grow incredibly powerful. The girls transform but are easily overpowered. Rate, feeling it's all her fault, attempts to stop the MegaByogen on her own but it proves too much and she is captured by Batetemoda. Queen Teatine, sensing something is wrong, begs the Earth to save her daughter. Suddenly a mysterious new Cure appears and saves Rate and the other Cures, allowing them to purify the MegaByogen and save the Wind spirit. Afterwards, the new Cure uses a new elemental bottle to heal Rate (though the latter is still not fully healed from her cold), while the other Cures wonder who she is...
