The delivery of online ordered things came along a box of biscuits that can turn one into a baby. Kanata eats it accidentally and turns into a preteen. Later Chris invites everyone over shopping. While in the book store, Kanata turns into a toddler and loses Miyu. Miyu looks all over for Kanata, but Kanata finds Wanya, Ruu, and Momoka instead and becomes a baby. Kanata is brought home sleeping with scared Miyu right next to him. In the end, Miyu hugs baby Kanata crying, and Kanata is brought back to being himself.
