Kurama looks out at the ocean, perhaps grieving the loss of Nana, while Kouta and Yuka wake up to find Mayu has run away. The episode delves into her past, and not surprisingly for this show, it’s horrific. Habitually sexually abused by her stepdad and shunned by her mother, one night she refuses to undress, and runs.
She doesn’t stop until she reaches the ocean, and seems poised to walk in and not come back. She’s stopped only by the dog Wanta, whom she assumes was discarded like her. Back in the present, Wanta (AKA James) is claimed by his owner, leaving Mayu alone again. She hides among crates in the cold, dark night, utterly miserable.
Some cops find her, but thankfully so do Yuka and Kouta, who remembered she hung around the beach a lot. They bring her back to the house, but she’s not sure why, because no one in her life has ever given a damn about her except to use her. It never occurred to her that good people existed.
While his penchant for “collecting girls” continues to irk Yuka, she doesn’t protest when he decides to let Mayu stay with them indefinitely. Mayu’s mother all too easily signs away guardianship to him. Wanta comes back to her (his old owner was not a good person, it seems) and she returns to school with a smile on her face, now in a much better place.
Kouta and Yuka return to college classes too, but inexplicably take Nyu with them. I understand how they might be worried about her wandering off again, but it just seems like a really, really bad idea considering how much they don’t know about her situation.
Sure enough, the professor of their new class is Dr. Kakuzawa, son of the head of the research facility where Lucy was being held. He takes Kouta and Yuka aside, warns them of the laws they’re breaking by having the girl in their custody, and makes Kouta agree to leave Nyu with with him.
Fearing the consequences and cowed by an authority figure, Kouta ignores Nyu crying out his name (she’s learning more words than just “nyu”), and later can’t help but shed tears over their separation. Yuka reproaches him for crying (“You’re a man!”) but then starts crying herself.
They get home and tell Mayu, who plants the seed in Kouta’s head that maybe the professor wasn’t telling the truth when he said Nyu’s family was worried and wanted her back. Gee, ya THINK?
Sure enough, Kakuzawa’s intentions with Nyu are anything but honorable. He strips her down, ties her up, and injects her with drugs. But while he’s still undressing in preparation to rape her, Nyu wakes up as Lucy, and plainly asks him who he is and what he wants.
Kakuzawa tries to give her his spiel about replacing the human race with superior Dicloniï, revealing his own sorry horns. Lucy plainly ain’t buyin’ it, and helpfully relieves him of his head, causing a fountain of blood and saying she doesn’t need someone like him.
Truer words have never been spoken. Like Mayu, she needs good people like Kouta and Yuka, particularly when she reverts to Nyu. It’s just a shame those good people aren’t the brightest…
