Shirakawa and the assault team can only stand around and watch in horror as Mariko continues to toy with Nana like a child rips wings off an insect. Only Nana is, horns and prostheses aside, a human being. Despite this, they allow 35 to have her way with Nana so she’ll be more cooperative. It’s frankly sickening to see other humans stand by and let this happen.
I know they see Dicloniï as an existential threat to humanity, but Shirakawa and the soldiers are abdicating their own humanity by allowing such sickening, wanton cruelty to occur. Lucy may be one thing and 35 another, but Nana is living, breathing proof that Dicloniï can coexist peacefully with humans. Mayu sees Nana and Nyu as sisters and Kouta and Yuka as their mom and dad.
And it’s Kouta who comes to Nana’s aid when no one else will, putting his own life at grave risk. Not only is Mariko eager to have more “fun” killing people, she resents the fact Nana has a friend, something Mariko didn’t believe was possible because, well, she’s been encased in a giant steel enclosure who whole damn life! I can’t blame Mariko for being the way she is, which is a direct result of the dehumanizing, self-defeating actions of the researchers at the facility.
Nana uses her remaining strength to keep him from being hurt, demonstrating she’s far more human than those who wish her dead. She ends up falling off a bridge into the water, and her fate is left unknown. However, when Nyu finally catches up to Kouta, she slips on a pool of Nana’s blood and hits her head. Lucy reawakens and kills Shirakawa and the soldiers one by one right in front of Kouta, whose long-repressed memories finally surface.
The story that unfolded in episode nine is thus completed, as Lucy followed Kouta’s family on the train out of Enoshima. Kanae claims to have witnessed a “girl with horns” killing lots of people at the festival, but Kouta doesn’t believe her. When Lucy appears, Kanae confirms she was the killer, but Kouta won’t hear of it, slaps Kanae, and orders her to apologize.
Kanae just wants to get Kouta away from Lucy, worried he’ll be her next victim and putting herself between the two, but Lucy snaps her in half, and then beheads Kouta’s father. When Kouta asks why she did these things when he thought they were friends, she calmly responds in her cold Lucy voice: “I didn’t kill you because we’re friends,” then vows to kill Yuka next.
Let me be clear: Lucy is this way because of humans. She killed the bullies because they bullied her; had they been nice to her she’d have been nice back. She punishes Kouta by killing those close to him because he lied to her. It may have been a white lie meant to protect her, but someone with her past didn’t make that distinction, and it doesn’t change the fact it was not the truth.
Back in the present, Kouta finally reconciles those newly surfaced memories with Nyu’s true identity, but he has little time to process them as Bando arrives ready to kill Lucy. She flees, baiting him to follow her, and urges Kouta to meet her at the stone steps. Kouta and Lucy have hurt each other gravely, but perhaps, like Shirakawa briefly hoped, there can be a resolution that doesn’t involve killing. Okay, that involves minimal killing. Bando obviously has to go.
