Rizumu has begun the Aurora Rising training under Kei coach but is faced with the challenge of getting the Pure White Wedding stones or else she can't compete in the Prism Queen Cup to even do the Aurora Rising. Meanwhile Mion takes the matter in her own hands by going to the Jonouchi resident to beg for the wedding stones. The conditions for the stones were that Mion and Serena are to have a dance off and Rizumu and Kanon compete in the Aquarium Cup. Whoever lasts the longest in the dance off and wins the cup gets the stones but Kanon adds yet another condition:If Rizumu loses, she must stay away from Hibiki. In the end, Rizumu and Mion pull through but Kanon still doesn't accept Rizumu and Hibiki because of his sneaky encouragement toward only Rizumu during the competition.
