Kanade is forced into appearing in the biggest event, the battle of the welcoming party. The battle will be between Popularity Five and Reject Five. Kanade, Furano, and Ouka will be appearing as the Reject Five.

¿Y qué es eso de que no 
perderán sus recuerdos?
Pourquoi elles ne perdraient pas
la mémoire ?
E como assim sem eliminar as memórias?
