Mentally, Nyū had the intelligence of a toddler, which gave her a very ignorant and sheltered view of the world, a very narrow sense of right and wrong as a child would have, and she was easily frightened by bloodshed and violence. Whatever the health of the island, Lucy's health falls into question as she weakens, coughing up blood as Chief Kakuzawa reveals that high-end usage of her powers reduces her body's integrity. Any other way risked harm to Kōta or rejection for herself, if and when he recovered his memories. While Kōta began to recover in the hospital and while Nana struggled with both Yuka's mother and her 'Papa' Kurama, Lucy was bound over by the Agent and taken back to the Diclonius Research Institute. After being imprisoned within the , Kurama informed Kaede that Aiko had died from her wounds, also asserting that she could have lived had they simply given up and that Humans only wanted the race to co-exist with them. Lucy is pleased, even in her state, to see the residents gathered. She also warned Nana to leave, calling their species 'real people' as opposed to Humans, and having no desire to hurt her.
Showing a feeling of control justified or not the Chief released Nyu, who showed modesty uncharacteristic of either Lucy or her former infantile self. Mamoru Kanbe Takao Yoshioka April 21, 2005 2005-04-21 September 3, 2013 is still settling in at home. Nyū matured significantly over those six months: she began to learn the basic morals and norms of society, learned how to speak properly, coherently, and in complete sentences, how to cook, clean, and, thankfully, to show at least some restraint on her sexual curiosity. The scientist even attempted to take Nyū hostage, before realizing just who her hostage was, releasing her in a blind panic. Feeding the puppy on breadcrumbs left him still hungry, so she felt forced to give most of her dinner to it. As they left, Nyū cried out for Kōta, placing the cousins in tears after they were well away.
Toward other opponents, however, her posture is straighter, more confident. Though Lucy and Nyū are implied to have been reborn, it's unknown if the third personality was reborn as well. While Lucy is gone, Nana finds her and tells her she will take Lucy back. The series reveals nothing about the background of Lucy's parents. She meets Bantou and promises to bring him Nyuu. As she left Maple House, Lucy heard Kōta plainly say that his memories of how his family died had returned, this while glaring at her.
Nyū was shot by Bando, to no better luck than Kurama's attempt. When Lucy leaves Maple House for the final time, she directly charges Yuka with the care of Kōta, knowing that she would care for him and also perhaps a shot at her one-time tendency to strike him. Nyū awoke restrained in the underground grotto beneath the facility, nude and with her horns starting to regenerate. The hat not only hid her horns but was the first actual gift she'd most likely ever received. Lacking anything to throw, Lucy tore the head off of the suddenly worshipful Unknown Man and launched it like a missile at Bando. To better show her growth from a mental toddler to an ordinary woman in the manga, Nyū refers to everyone using proper Japanese honorifics.
. Realizing that Nyu's state of mind rendered her powerless, Kurama tried to use her or Lucy's life as a bargaining chip to stop the Chief's plans. Realizing Yuka had left, Kōta pursued and found her on Yuigahama Beach. Not ever wishing to leave his side, Lucy forced her personality as far back as possible, allowing Nyū to predominate. Mariko, who had bombs embedded in her since birth, knew they might soon explode and sought to trade her life for her father and Nana's. In this limited guise, she forgave Kōta as Kanae. With Yuka Lucy apparently viewed Yuka as a rival and an obstruction from the very start.
This determination added to the pain of their melted body to cause them to leave it once and for all. It is much more comical and light-hearted than the main series, with far less blood and violence, although it does contain the present in the rest of the series. Nana rescued Kurama, cast off the tower of the Sea Candle by Lucy's power, but it seemed soon there would be no safe place to flee. Also, despite her critical position as the Diclonius, Lucy didn't seem to have any interest in perpetuating her line and legacy. Mayu's mother happily gives Kohta guardianship of Mayu. The Voice first called out to her after the death of her at the , and Lucy heard it even more as she feared Kōta had betrayed her. When pressed as to why he would do such a thing given his vow of hatred towards Lucy, the fading Kōta claimed he wanted to avoid leaving things unresolved, as he did with Kanae.
Lucy made it obvious she didn't care for humans and didn't count them as people. Kōta surprised her by calling out the iffier parts of her story and by not wanting her to leave. This change first occurs when Kurama appears with the guards in the facility, as she straightens up and walks through his guards without lowering her head once as she kills them. As Nyu, she could stay with him as she wanted without him being reminded she killed his family and without her living forever racked with guilt for ruining his life. Before the two ghosts leave and end their protection, they remind Kōta of when and where they first met as children. Lucy did pause to apologize to the remains of her younger brother saying that even though he had done nothing wrong, there was no bright future for their kind and that their race must end.
Resolving to put Kōta out of her life, and herself out of his, Lucy pretended to be a coherent Nyu, saying she had regained her memories and found her family. And when they met again at Maple House, she tauntingly asked Nana if she was there for a rematch though she converted back to Nyu before this could happen. Author Stephen King once said that, from a remove, evil could seem darkly glamorous and grimly seductive. When Kōta chastised her for this, Nyū made plans to shock-scare him by jumping out of a closet when he next passed by it. While Nyū became aware of or concerned about the existence of Lucy, she seemed to remain unaware of the Voice, a perhaps deliberate move on Lucy's part. In spite of this desire, Lucy viewed her impulse to kill humans, spurred by The Voice, as natural and had difficulty fighting it.
Professor Kakuzawa Yu's decapitated body is found by his assistant and Kouta. The first episode is infamous for it's heavy handed use of gore, and is not for the faint of heart. As she broke down further, she saw her orphanage as horrific specters, also saying there was no place for someone like her, and that wasn't the same as lying to a real human being. This hope proved pointless as the false satellite launch went off without any interference. The German titles do not translate exactly to those of the Japanese titles, except in some cases.
Feeling this was what she must do, Lucy continued killing people anyway. Oddly, at this time, Kouta never learned or asked the name of his new friend. It all starts out with her imprisoned on an unidentified island where she is bound and her face is covered with a metallic mask. After witnessing her murder at the hands of the orphanage , she began to develop a deep hatred of Humans, killing whole families just to use their houses, without regret or guilt. On the train, Kanae insisted her story was true even as Lucy strolled into their car on the moving train. Before he knew it, Lucy stood above Bando, firearm in hand, his position all but hopeless as Lucy began to slowly maim and dismember him, taunting his curses and expletives as the torture kept on.
