MARs and Callings are putting on a Prism Show for Christmas, but Kyoko tells MARs that afterwards, the members will compete individually in tournaments. Meanwhile, Kaito, a boy from Uru and Eru's kindergarten, hopes for it to snow on Christmas Eve, because his late grandmother had promised it to him as a birthday present. With help from Callings, Rizumu, and Mion, Aira invites Kaito to their Prism Show, where they perform a Prism Jump, "Miracle Christmas Snow", which causes it to snow for real.
