X-day
Ayu and Nina's class plans a costume party. Everyone wants Ayu and Kaji to be Romeo and Juliet. In the meantime, Nina dresses up as Sherlock Holmes and hopes to create more memories with Tsujiai but cannot find him as he is dressed up as a robot. Nina seems to notice him a bit while she was dancing with a boy who was actually the prince of the Magic Kingdom but afterwards, he disappeared. Maya tries to find the last holy stone before Nina.

Note: The classical piece ever known to be played is "The Blue Danube" whereupon Ayu (as Juliet Capulet) and Tetsushi (as Romeo Montague) dance the love waltz.
