No matter how many kaiju Akane made and Alexis embiggened, they were never able to defeat Gridman. As a god suddenly hemmed in by the intolerable rule that her kaiju will and must always lose, she finally snapped and took matters into her own physical hands.
Rather than use her box cutter to carve a new kaiju, she stabbed Yuuta with it, then wanders away in a haze, hoping that maybe, just maybe, the torturous cycle is over.
It’s not that easy. She missed Yuuta’s vitals, so she didn’t kill him, though he seems to be in some kind of coma. With all the custodian kaiju beheaded, nothing in the city resets, and the chaos just remains. Worse still, as far as Alexis is concerned, nothing’s over.
Lex believes Anti to be the “next Gridman in line” and thus needs Akane to keep creating more kaiju for him to use. When she categorically refuses (pointedly saying she “can’t”, not “won’t”), he simply brings back all the kaiju she already made…at the same time.
A scenario entirely beyond Akane’s control and will thus unfolding, Anti arrives in the hospital room, not to apologize for what he did as a kaiju but to settle his debts as a human. He’ll fight off the kaiju as Gridknight, as Neon Genesis set to work repairing the computer so Yuuta and Gridman wake back up (they can’t sortie without Gridman).
In a brief dream sequence before he wakes up, Yuuta sees Gridman in the mirror, and it dawns on him: He’s not Yuuta; not really. Rather, he’s Gridman dwelling within Yuuta, using his body and mind as a vessel. The matter all along, then wasn’t that Yuuta had amnesia; he was never Yuuta to begin with, and thus whatever memories he had as Yuuta were as repressed as the real Yuuta himself, whom we’ve apparently never even met.
Shou is feeling particularly useless this week, and we can’t really blame him; aside from being the only person with the time to stay by Yuuta’s bedside when he wakes up, he is pretty useless this week. He can’t dissuade Gridman from a course of action that could get his friend killed.
Instead, Yuuta and Neon Genesis mobilize and fight beside a battered Anti against the kaiju “greatest hits,” destroying them all. Alexis can bring back the defeated kaiju all he wants; the fact remains they exist only to be beaten by Gridman.
Meanwhile, Rikka seeks out Akane, not to seek revenge or to give her a piece of her mind, but just to be there for her as a friend. Yes, Rikka may only think she’s Akane’s friend because Akane “set it up” that way, but Rikka doesn’t care; it doesn’t change the fact they are friends, through and through.
Before Rikka can hear what Akane thinks of her, they’re interrupted by Alexis, who labels their conversation “pointless” and tells Akane that new kaiju are needed post-haste. Again Akane tells him she can no longer make kaiju, but Alexis rephrases his position: he’s going to have a new kaiju, even if he has to transform Akane herself…which he promptly does, much to her and Rikka’s bewilderment.
Thus the downward spiral of Akane’s world reaches a new nadir: in which the creator of the world herself prepares to become just another one of the monsters programmed to fight Gridman. This seems to be breaking some fundamental rules of the “game” that’s been played so far, but Alexis doesn’t seem to mind. If Akane really does become another kaiju, isn’t she just as doomed to lose as the ones she created…or is that just another rule poised to be broken?
