Ep 12. Quagmire

Mariko enjoys playing around with Nana since she is only allowed to kill her. Kohta arrives at the scene and Nana saves him by falling into the ocean. Nyu then arrives, calling out to Kohta and the research work gives orders to kill Nyu and Kohta, but she reverts to Lucy and saves Kohta by repelling bullets using her vectors. This makes the sealed memory of Kohta's sister's and father's murder surface.
