Wonder Egg Priority is back after an recap week, and everyone is wondering if Neiru is sick or something, because she’s inviting everyone to her place. The other three girls soon learn that her “place” isn’t remotely like any of theirs, and not because it’s a mansion.
In fact, Neiru seems to live at work. When the others arrive they sit in a theater and watch a video presentation of technology the Aonuma group is working on that can convert people’s dreams to video, enabling them to watch Neiru’s egg battle on the bridge.
The question rattling around everyone’s heads is “who is Neiru?” and her invitation to her home and workplace seem aimed at attempting to answer that question. Her assistant tells them she’s a literal genius and member of the Japanese branch of Plati, a MENSA-like genius organization.
We also learn that Neiru doesn’t know her parents because as far as she’s concerned, she doesn’t have any. She was born via artificial insemination of a member; a planned pairing with no emotional connection between the egg and sperm donors. Is it any wonder she’s such a logical person, in addition to being a genius?
The girls take an elevator to level B9 (presumably deep underground) where Neiru takes them to her habitation area, which is full of books and strewn with papers. There, Momo breaks out the takoyaki grill, and after they eat, she and Rika paint Momo and Neiru’s nails, with everyone getting the same purple accent on one finger so they match.
Momo is very skilled at painting nails, which leads to discussion of everyone’s futures. Momo wants to be a dietician; Rika wants to live abroad and marry a foreigner; Ai wants to try living alone. When they turn to Neiru, she changes the subject, and then leads them behind a curtain to show them the reason she invited them.
In the next room is a capsule containing a an albino girl. She’s Kotobuki Awano who like Neiru was a genius born at Japan Plati. She became a doctor of psychiatry, and in order to attempt to analyze “the mysteries of life” she conducted near-death experiences on herself. After one of these, she didn’t come back, leading to her present persistent vegetative state.
Neiru reunites with Kotobuki in an Egg Dream, on the bridge, when she’s being pursued by a Wonder Killer based upon a jealous rival scientist whose job he believes she stole. Neiru just wants to know why Kotobuki didn’t come back, and her friend’s response is poetic: it’s said you see a field of flowers in the moment before death; she wanted to pick one and bring it back to her.
Kotobuki levels with Neiru: the her in the normal world is already dead; her body is simply a container. But in exchange, she was able to confirm that parallel worlds do exist, like the ones in the fantasy stories she loved. She likens what happened to her as having her mind and body abducted by “innocent sorrow”.
Neiru is determined to go to the place where Kotobuki died and bring her statue back to life, but she’s not listening. Kotobuki died in an abstract place Neiru cannot go. Meanwhile, the government will soon come for her physical body, and she “doesn’t want adults touching it.” So she’s asking Neiru to do the thing she can’t do herself, now that her body and soul are separate: disconnect the life support.
Neiru really doesn’t want to do this, but Kotobuki says it will be fine; after all, Neiru made new friends, and she can tell they’ve already “softened” her a bit. Kotobuki wants Neiru to enjoy her life with those girls, while she’ll befriend them in another “world-line”.
Their talk is interrupted by the Wonder Killer, Dr. Seki, who’d always wanted to dissect Kotobuki, underscoring the importance of keeping her body out of adult hands. When he nabs Kotobuki, Neiru powers up her weapon and uses it to fly to where Kotobuki is and snatch her. Then Seki gives them a math question of all things that turns out to be a trick question.
After that, Kotobuki bids Neiru farewell, asking her to take care of her body in reality, and Neiru agrees. We pull back and see that Neiru’s assistant is watching the video of Neiru’s dream. Back in the present, as Neiru prepares to switch off Kotobuki’s respirator, she gets strong pushback from both Rika and Momoe, who think it’s “too much” to kill a person in the real world.
Neiru maintains her logical perspective, which is that Kotobuki is already effectively dead, and when Momoe pushes back by saying that as her friends they’re worried about the trauma or baggage she might incur. Neiru says she won’t get “sentimental” about stopping “a dead person’s respiration”.
At an impasse, Rika and Momoe storm out. Ai, stuffing her face in her hood, follows them at first, then turns back. Momoe and Rika agree that perhaps Ai can get through to Neiru on her own, since she’s closest to her of the three of them.
Then Momoe and Rika walk in on a conversation between the Accas and Neiru’s assistant discussing how Neiru has gotten closest to “the truth behind the temptation of death,” and how they are the “root cause” of why they’re fighting. It’s not as if didn’t think the Accas were up to something underhanded, but it’s particularly chilling to hear them discuss it openly.
When Ai returns to Neiru, she’s sitting in the dark with a compact planetarium projecting stars on the walls and her body. Ai, armed with ample emotional intelligence in this instance, says she’s not there to convince Neiru to do or not do anything. She’s there to hear more about Kotobuki. Neiru says she didn’t want adults to touch her; Ai says if only she’d said that, Momoe and Rika would have better understood her.
Ai then recalls when she and Koito tried fortune-telling using Kokkuri. They asked if Koito’s crush (whom Ai assumed to be Sawaki-sensei) liked her back, and the coin said yes. Ai didn’t think she’d moved the coin, but when she saw how happy Koito looked, she couldn’t have moved it either. Ai wonders if she actually did move it without knowing to make her friend happy. That, she says, is fantasy.
Ai applies that same principle to Kotobuki’s life support system. She brings her finger right beside Neiru’s on the Shutdown button—their purple nails matching—and the button is pressed like the coin was moved: by one of them, by both of them…and by neither of them. Kotobuki in voiceover then recites famous quote by Baudelaire:
“It is the hour to be drunken! To escape being the martyred slaves of time, be ceaselessly drunk. On wine, on poetry, or on virtue, as you wish.”
Kotobuki Awano’s death wasn’t the result of contempt for her life or a desire to end it, but pursuit of the ultimate truth for which all people of science strive. She escaped her physical bonds and the yoke of the waking world, freeing herself to explore other worlds.
That said, Kotobuki was still sentimental about and protective of her physical body, and while she knew it was selfish and painful to ask her friend to stop that empty body’s functions, she also knew Neiru would do what she asked, then go on living and getting “ceaselessly drunk” on the enjoyment of that life with Ai, Rika, and Momoe.
