Kouta and Yuka turn out to be fine; they left the bedroom before Lucy got up to leave. She and Nana prepare to fight, but Mayu comes between them more than once, and very nearly gets killed for trying to be the peacemaker. Mayu’s pleas remind Lucy of Kouta’s in the past, and she reverts to Nyu once more. Thanks to Mayu’s decency and diplomacy, Nana is welcomed to the dinner table.
From there we’re sent back to the past, when Kurama is first recruited out of college by his friend Professor Kazukawa. They managed to capture a young but murderous Diclonius and have commenced horrifically cruel experiments to test the strength of her Vectors. Kurama is initially not okay with this, but Kazukawa impresses on him how dangerous and unable to coexist with humans they are.
Kurama comes around when the Diclonius Three escapes and goes on a bloody rampage, and very nearly kills him before Kazukawa shoots her in the head with an armor-piercing round, killing her. After committing more than ten infanticides Kurama stops seeing them as simply humans with horns and starts seeing them as an enemy and a blight to be wiped out without mercy or humanity.
Poetic justice strikes when his own daughter is born with horns; he later realizes that Three infected him when she touched him with her Vectors. He aims to kill her like all the others, but his wife, not far removed from major surgery, fights for her daughter’s life with all the strength she has left. She ends up dying of blood loss in the nursery, but not before convincing Kurama to spare their child’s life.
Nana may not be Kurama’s daughter, but she was a proxy for the sliver of fatherly love he had left, which enabled him to free her. That hardly makes the horrible things done to Nana that resulted in her ending up a bloody naked mess (and having dreams about “naked crucifixion”) any less horrific. But on one side of him is Kazukawa, whose word is law, and on the other is the truth that Dicloniï seem to inevitably end up uncontrollable murder machines.
Needless to say, he should have never set foot in that god-forsaken facility. It’s sad that just before Shirakawa begins to unleash Kurama’s biological daughter, Number 35—the “most dangerous” Diclonius, sporting twenty-six visible Vectors—Nyu and Nana are happy as clams with Kouta, Yuka, and Mayu. (A bit of trivia: Akira was designated Number 28, so 35 is seven higher.)
I can’t imagine we’re headed for anything resembling a happy ending here, so I’ll take the happy, peaceful moments in this and future episodes where I can get them.
