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...
And they launched a sneak 
attack on Seiran Island.
وقد شنّوا هجوماً خلسةً على جزيرة سيران
Letztendlich diente alles
dem Zweck, Seiran anzugreifen.
Lanzaron un ataque sorpresa
en la isla Seiran.
Realizaron un ataque sorpresa
en la isla Seiran.
Pour pouvoir lancer
une attaque-surprise ici.
Così hanno potuto lanciare
un attacco a sorpresa alla nostra isola.
E eles fizeram um ataque
 surpresa na Ilha Seiran.
