After killing many facility employees, Lucy escapes from the facility where she has been contained. However, a sniper shoots her in the head as she is escaping and she falls into the water. When she reaches the shore, she doesn't remember her past and can't even speak except for saying "Nyu". At the shore, Kohta and Yuka find Lucy and try to help her. Since she doesn't seem to understand the language, Kohta and Yuka decide to bring her to Kohta's new residence and decide to call her "Nyu." When Kohta shows a seashell to Yuka saying that it is his little sister's memento, Nyu breaks it since she didn't understand what he was saying. Kohta gets very upset and Nyu runs out of the house.
