Prologue
After the Mages intrudes Liberum, the Eclipse Celestial Spirits retreat from the battle to their gates, each one leading to a different area inside Astral Spirytus. Gray, as the other Mages, receive a Banishment Key and enters Cancer's gate. He then finds him self in a dance ball, facing the Giant Crab, Cancer, with the latter inviting the former to dance. Gray then wishes that he went for a different spirit, as he watch the Celestial Spirit dance, with the latter asking the Ice-Make Mage to show him his moves.

Eclipse Cancer then taunts Gray by his moves, stating that they're going to have a dance battle where you get life points by dancing. The latter starts dancing a little before kneeling from embarrassment, as he can't "dance". Cancer mocks his face expressions ironically, before throwing two red boots and transferring them to Gray's feet. He then states that they're the legendary Red Shoes that will make him dance forever and thus Gray starts dancing professionally, much to his agony. Cancer then, dancingly shoots a cutting beam from his claw, striking what seems to be his opponent's heart, unwrapping the "other gray" in him. The new Gray now starts dancing with super ingenuity, amusing the Eclipse Spirit. He then realizes that he's being defeated and engages with Gray in a passionate dance battle. Gray turns the dance floor into an ice rink and starts ice-skating, much to Cancer's surprise, as he watch him implementing a cool triple ice axel, astonishing the Spirit. As Gray executes a couple of spinning moves, Eclipse Cancer recognizes his near defeat and declares the second stage of the dance battle, where they fight as they dance.

Battle
Cancer delivers the first attack, with Gray making the first dodge in return. After equivocating another attack, Gray uses Ice-Make: Ice Cannon at his opposition, just to be deflected easily by the Eclipsed spirit's metal-like claws. As Cancer taunts him fore more, Gray keeps dancing and fires his Ice-Make: Lance, just to be swerved again. Just as Gray uses Ice Impact, Eclipse Cancer jumps in the air, casting his Double Claw attack, shattering Gray's ice, leaving the latter with one life point left.

Eclipse Cancer states that the battle is over and charges at Gray, just for him to be caught from behind by the Ice Mage. Gray then preform a fascinating show alongside Cancer, much to his passion. Eclipse Cancer the, overwhelmed, states that Gray can do what ever he want with him, in which Gray replies that he will send him home "cool". Gray then charges at Eclipse Cancer with his Red Ice Blade: Seven Slice Dance, striking him several times, defeating him.

Aftermath
After that, the cool inside Gray is concealed again, with normal Gray disgraced at his dance. The Mage is walks to the defeated spirit, threatening him not to tell anyone that he was dancing or else he will kill him, as Cancer, befitting his carefree character, admires Gray's angry face, before Gray force close his gate.
