Episode 7 - Episode 10 No information No information No information No information The second battle between Lucy and Nana is more of an ambush on Nana's part. After meeting the young diclonius, Mayu takes Nana to the Maple House in order to both get her something to eat and to glean more information on her and Nyu's connection, since they both have horns. Kouta is eager to know of the latter as well, and invites Nana in but struggles in opening the door. Though it's Nyu who's present when the door opens, Nana only knows her as Lucy and attacks her right away. Nyu isn't awake for very long, as the combined efforts of Nana's attack and a fever no one yet knew she had exhausted her.
