Finding Nyu at last, Kouta races towards her and demands to know where she had been, since they were all so worried about her. Lucy then begins to realize that he does not remember their tragic shared past, and shocks both him and Yuka, by speaking clearly and coherently for the first time since they've known her. Sighting the pair holding hands, she trips Yuka with her vectors and causes her to fall. The sight of Kouta comforting Yuka as he did when they were children only reinforces the thought in her mind that they can never be together after what she had done to him.
Bidding him farewell, Lucy attempts to say that she has her memories back and has remembered her home, but Kouta stops her, saying that the Maple House is her home. He also protests of how worried he would be about her if she left, and challenges the truth of having found her home, if she is still on the streets, refusing to leave her be until she offers specifics of her supposed home. His simple, heartfelt offer of home, love and friendship goes to war with her murderous inner voice. Finally, she protests that he must remember the tragic train ride of eight years prior, which does in fact trigger a new flashback in his mind. Just as she is about to openly confess her sins against him, she reverts to Nyu once more.
Wailing, Nyu throws herself on him and asks for a hug. While still wondering about his short-lived memory, Kouta gains Yuka's permission to hug her, which she grudgingly gives amidst nearly instant regrets. Kouta holds a tearful Nyu and assures her they will always be together, stirring a happy below-the-surface memory of much happier times.
