Akane has a dream in which Tonkawa and all of the other people she killed are back, but wakes up in the dark in her room, the weird “ceiling city” in the background, and Alexis looming over her, waiting for her to complete her next kaiju.
Yuuta, Rikka, Shou, and Neon Genesis all determine that if Akane is being controlled by an alien, they have to at least go to her house to talk with her. Somewhat hilariously, that means simply walking out the door to the junk stop and going next door to Akane’s house, but when the door is forced open, there’s nothing on the other end but…more “back-end” city.
Writing the slogan of NERV from Eva in his notebook, Shou gets back to his studies, saying that even if he, his world, and everything in it was made by Akane, there are still things that need to be done, like studying for midterm exams. After all, there are no kaiju attacks for several days in a row.
Yuuta, Rikka, and Gridman muse about why Akane built this world: was it to find tranquility, or refuge from the world of the other gods? Rikka thinks it wasn’t because Akane was/is weak, merely that she’s sensitive, and as she says so, the very sunset she beholds seems to speak to that sensitivity.
When a frankly fucked-up-looking kaiju suddenly disturbs the peace, I was wondering if Alexis had simply used one of the incomplete kaiju models Akane didn’t seem motivated to finish.
It certainly doesn’t take much for a full-powered Gridman to take it down, while a determined Anti in kaiju form doesn’t give him much more of a fight. Later, we learn that unique to all the other kaiju she’s created, Anti alone has “life”, which makes it possible for him to read the hearts of others, even think about or look out for them, something true kaiju would never do.
But Akane doesn’t seem to have a use for a kaiju with feelings, and so basically tells him to buzz off and do whatever he wants. Later that night, out of the husk of the dead weak kaiju, another, more aggressive-looking kaiju emerges.
It proceeds to chop the heads off all of the massive “custodian kaiju” that dot the city, and the pall of fog/poison gas they emit is lifted. When Gridman sorties once more, this new kaiju is more than a match, he can read all of Gridman’s moves and outmaneuver and outgun him.
It isn’t until this pointy-headed monster is looming over a trashed Gridman flat on his back, surrounded by flames, that Anti springs back into action, this time saving Gridman from the kaiju. His logic is that in order to crush him, he must fight together with him to defeat that which would crush him first. He doesn’t just want Gridman crushed by anyone, he wants to be the one do it.
Anti then transforms into a Gridman clone, or “Gridknight”, and with a shimmering purple energy donut, cleaves the kaiju—which represent’s Akane’s heart—in two. Perhaps that’s why Akane seems so down when she appears in the Junk Shop and inspects the computer used to interface with Gridman: one could say Anti just “broke her heart”.
In return, now knowing that Yuuta and Gridman are separate entities, she suddenly embraces Yuuta, then pulls away, revealing a bloodied knife as Yuuta falls to the ground.
For the first time, she’s foregone the use of kaiju or other godly powers and bloodied her own hands to rid her world of someone messing everything up. It would seem, then, that she’s made her choice, even if she doesn’t seem particularly happy about it.
