MARs will be releasing a new song, "Hop! Step!! Jump!!!", and entering the Pure Crystal High Heel Cup for the Pure Crystal High Heels. After disagreeing over whether Yuri, Mion's friend from New York, should choreograph their routine, Rizumu and Mion end their friendship. To settle this, Yuri challenges MARs to a game of streetball with Serenon, where she will help the winner with their choreography. Rizumu later learns that Mion enlisted Yuri's help to increase their chances of winning, and the two reconcile. During the game, MARs pulls off a move that allows them to win. They later use it as the Prism Jump "Cheerful Hip Hop Win" when debuting their song.
