Synopsis

After West Genetics sends their fourth-year Pandoras to reinforce East Genetics, the West Genetics Academy is attacked as well and is soon surrounded by the Nova. With the fourth-years too far away to help them, Yu-Mi and Elize lead the remaining fourth-years and the Military to the front lines while the rest of West Genetics' Pandoras and Limiters are ordered to guard the Academy. However, the Nova soon release Nova Forms: Pandoras they had absorbed earlier at East Genetics who are now infected and under their control. Meanwhile, Satellizer is angry that Kazuya might see her only as a replacement for his sister; but before he can explain, both of them (along with Rana, Ganessa and Arthur) are called by Sister Margaret to defend the underground Ravensbourne Nucleotide facility which holds the body of Maria Lancelot (the first and mother of all Pandoras). As the Nova Forms attack the Academy, a small group of them led by Cassie and Milena manage to breach the underground facility. Sister Margaret realizes the Nova Forms' target is Maria's body and laments the fact that the same Stigmas that give a Pandora their power are also responsible for turning them into Nova Form.
