My Cake Is the Best.Riiya's grandpa stops by after getting lost in the woods. The principal pities him and gives him all of the school lunches to eat, leaving everyone at school to starve. While Riiya, Chacha and Shiine are walking through the woods, they stumble across a house that has a delightful smell of cookies. The witch who lives there, however, was sent by Sorges to eliminate Chacha. She invites them in and lets them eat her cakes, which taste terrible. Feeling insulted, she challenges Chacha to a baking duel: if Chacha can make a better cake than her, the witch will release her and her friends. With a little help from Seravy, Chacha makes a better tasting cake than the witch, but she tries to kill Chacha anyway, saying nobody should be a better baker than her. Chacha transforms into the Magical Princess and defeats her.
