After Daruizen infects Cure Grace, the other Cures arrive to rescue her, only to arrive too late. They take Nodoka back to her parents, who rush her to the hospital revealing that the illness she is suffering from seems similar to her previous one. The girls talk and wonder if Nodoka was infected by a Mega Part before and the Healing Animals reveal that the Byogen generals were created from MegaByogens which have evolved to the most advanced stage. The girls go to visit Nodoka at the hospital where they witness the MegaByogen being purged from Nodoka by the combined effort of both her and Rabirin. After chasing the MegaByogen down, they find Daruizen is waiting for it to evolve, and everyone is surprised when it turns into an almost exact duplicate of Daruizen, named Kedary. Kedary proves to be very strong and the Cures have a hard time fighting him until Cure Earth uses her new elemental bottle to trap him, allowing the other Cures to purify him using Healing Oasis, killing him for good. However, after the fight, Daruizen reveals to Cure Grace that he remembers how he came into being: he was born from Nodoka after she was infected by a MegaByogen seed causing her initial illness. Daruizen leaves Cure Grace struck dumb by the revelation, but afterwards she resolves to do something about him.
