Full Throttle! My Rhythm!.Nagihiko is filling in for some players at a basketball game. Meanwhile, Amu and Yaya tell try to make Rima feel guilty about dumping Fuyuki Kirishima. During the game, Kukai comes in and blocks Nagihiko's shoot. Later at the Garden, Nagihiko and Kukai have an arm wrestling fight as Amu sees Nagihiko's egg move. Kukai barely wins. Later, Nagihiko asks Kukai his true motive for visiting and Kukai just says if Nagihiko has found an answer yet. Also, Easter has created a machine to help lure X Eggs without Ikuto's Death Rebel. Nagihiko, Amu, and Tadase then meet three kids who call themselves "Urban Street." Nagihiko shoots a basketball and everyone is amazed. His egg moves slightly more. The next day is the exhibition game. Amu goes and gives Nagihiko his uniform for the big game. As the game starts, Easter uses its new machine and extract X Eggs from the basketball player. Amu transforms into Amulet Heart while Nagihiko challenges the X Characters to a match. He then thinks about his childhood where he remembers "Urban Street" and how playing basketball with them made him gain "his own rhythm." Rhythm finally hatches and Nagihiko Character Transforms into Beat Jumper. He makes a Beat Dunk and wins the game against the X Characters and Amu purifies them. Later as Nagihiko chats with "Urban Street," Rhythm tells Ran, Miki, Amu, and Su that they are cute, which sends Miki head over heels. Rhythm smiles and winks.
