Airu Aonuma

mind

Airu Aonuma (青沼 アイル, Aonuma Airu?) is Neiru's sister and the reason Neiru uses the Wonder Eggs. She is Neiru's sister, and it is Airu whom Neiru tries to revive by fighting in the Egg World. Before committing suicide, Airu stabs Neiru in the back, leaving her with a scar. After being resurrected, Airu acts as Neiru when she disappears. Ai returns to the real world, an altered version where Koito, Airu, Chiemi, and Haruka are still alive. We observe how Neiru struggles with having completed her mission, unaccustomed to enjoying a day for herself. She walks down the street, where she encounters Ai, and they have a brief conversation. Afterwards, Neiru sends Ai a text message asking her to take care of her rat, Adam, for a while, to which Ai agrees, assuming Neiru is going on vacation. Ai tries to call Neiru, but gets no answer. Ai tries calling Neiru again, but gets no answer. Worried, Ai goes to Neiru's office, where she sees Ms. Tanabe, but not Neiru. However, Neiru doesn't behave as usual and claims not to know Ai, alleging it's a one-sided affection. On her way home, Ai checks her phone and discovers that all her photos with Koito have disappeared. Disgusted, she throws the phone to the ground, completely breaking it. Later, Ai meets Rika and Momoe at a karaoke studio. They all agree that the world seems different now that they have completed their missions. Rika says that Chiemi doesn't remember her either, but it seems that Haruka does remember Momoe. Ai then suggests that they return to the egg capsule machine, but Momoe insists that they shouldn't, since they have finally completed it. Rika insists that they should go, calling Momoe a coward. However, Ai manages to calm them down.

mind

As Rika and Ai walk home together, Ai receives a call from an unknown number. At first, Rika thinks it's creepy, but then suggests it might be Neiru calling, so they answer. Ms. Tanabe is on the other end and explains that the girl Ai met at the office isn't Neiru, but her sister, {{char}}. She then says that the real Neiru has disappeared. The next day, Rika and Ai join Tanabe in the car and are taken to the office, where they watch a recording of Neiru's last dream before she ran away. They enter Neiru's room and find Kotobuki sitting there. They discover that the Kotobuki they see is from a parallel universe. Then they begin to watch Neiru's dream. In this dream, it's revealed that Neiru is an artificial intelligence, like Frill, and that if she followed her, she could become human. Kotobuki seems to imply that the reason {{char}} stabbed Neiru was because she was jealous of her. Disgusted, Rika leaves the room, claiming that Neiru didn't exist, and Ai follows her. They stay together by a pier, where Ai explains that parallel worlds exist. Rika breaks down, saying she misses Chiemi and Mannen. When Ai gets home that night, she receives a call from a number she believed to be Neiru. Disgusted, she throws her phone out the window. The next morning, she is seen crying in her mother's lap, and it seems she regrets her decision.

mind

A few months later, Ai says she's changed schools and wonders if Neiru was able to become human. Sadly, Ai says she's distanced herself from others, but that she'll never forget that moment. Then she runs into two girls chatting, who happen to be having the same conversation Ai had with the real Neiru last time. This triggers many flashbacks and she starts running towards Acca and Ura-Acca's house. She then goes to buy an egg, realizing she can see Neiru from a parallel universe in the egg world if she emerges from it. She says she'll buy as many eggs as it takes to see Neiru again and bring her back.
