Shiori, who Juri got a secret crush on, has transferred back to Ohtori Academy. Juri, however, is so cold to her. Shiori thinks the reason is that she took a guy she thought Juri had a crush on away from her. But Juri tells her that she didn't even care about that. Shiori wonders then whose picture is in Juri's locket. One day, Juri finally decides to throw her locket away. However, someone picks it up and puts it in Shiori's dorm room so that Shiori will find what's inside. Now Shiori knows that Juri has been suffering from the secret crush on her. Shiori feels relieved from the sense of inferiority that she has been suffering from and struggling to get over with for a long time. Besides, she even feels a sense of superiority to Juri. However, she is also upset with the way Juri has been looking at her. "I understand." says Mikage to Shiori "I suppose you have no choice but to revolutionize the world. The way before you has been prepared."
Shiori et Juri ont grandi ensemble et étaient les meilleurs amies du monde jusqu’au jour où la première a volé le petit copain de la seconde. Aujourd’hui, Shiori est de retour à l’Académie Ohtori et aimerait regagner l’amitié de Juri. Mais curieusement, cette dernière n’en veut pas du tout à Shiori. D’ailleurs, elle n’a jamais aimé ce garçon. Mais alors, à qui appartient la photo qu’elle porte jalousement en secret dans son pendentif ?
