The girls have to deal with the aftermath of the Ouroboros attack. Their fighting power has been greatly reduced, and they soon find out that things are worse than they had feared when some of the members are corrupted by the darkness...
No matter how many girls from 
the UC class you bring—
—مهما أحضرتِ من فتياتٍ بفئة يو-سي
Die UC-Class sollte
bloß nicht übermü…
No importa cuántas clase UC traigan…
No importa cuántas clase UC traigáis…
Quelques UC qui se liguent
contre moi ne vont pas…
Potete affrontarmi tutte insieme,
ma finché siete delle classi UC—
Não importa quantas meninas
 da Classe UC venham...
