As Karasu fights his way through Noein’s mechanical horde, Atori shows up to offer some assistance. Atori tells Karasu to find Haruka and that he will keep the army busy. Karasu is reluctant at first, but eventually agrees. Despite being greatly outnumbered, Atori manages to tear through the enemy forces with little trouble, using his energy to transform into a giant construct that tears through the machines with no trouble.
Meanwhile, Noein continues to coax Haruka into helping him achieve his goals. While Yu makes an effort, it proves futile and Noein is able to absorb the dragon torque into his being. This enables him to reach out to other dimensions and start to consume them.
In the present, the Magic Circle Project continues, but eventually loses control of the quantum event. They try everything to stabilize it, but it all proves futile. The Ouroboros activates and a portal to Shangri’La is opened. Almost immediately destructrons start to flow through and begin tearing up the city. Despite being one of the few people aware of the last attempted invasion by these things, Isami quickly declares that they are “impossible”. While everyone else in the city panics and flees; Ai, Isami, and Miho stand firm, confident in the idea that Karasu and Haruka will be able to avert this multi-versal disaster.
Haruka finds herself in a void where the time drifter tells her that she has to choose a future. Somewhat contradictorily, he tells her that having only one future will doom everything as there will be no choice, leading to pain and suffering.
We see the people of La’cryma are suffering a similar event to the people of the present. Amamiku rushes to find Lilly and tells her that she’s gathering people to the surface. Her goal is to really look at the world, thus verifying its existence and, hopefully, buying some time and slowing down the process.
Atori, seeing that our present is in danger, rushes through the portal to hold back the destructrons. He does OK, but finds that there are so many that he isn’t even putting a dent in it. He decides to take a different approach and uses his energy construct to clog up the portal so that they can no longer get through.
Back in the lab, the multiversal convergence causes the Koriyama of another universe to appear. Suffice it to say that everyone is a little weirded out by it. Even Koriyama is a bit unsettled by the sight of his own body lying on the ground dying from a gunshot wound. Shinohara tries to double down and shoots the newly appeared Koriyama. Despite pointing right at him, the bullet fires wide.
Koriyama nonchalantly says that this version of him can’t be shot. How? What? That makes no sense. You know what? I’m just going to use the Lost method and chalk it up to magnetism. Freaking magnets, how do they work?
Tobi sends Kosagi back to La’cryma and tells her to destroy the computer as it doesn’t truly validate existence. She goes on to say that humans acknowledging each other is the best way to reaffirm our own existence. Kosagi manages to transport back and destroys all of the La’cryma computers.
Yu/Karasu confront Noein. It’s unclear as he shifts back and forth between forms over the course of the confrontation. It’s somewhat justified given the dimensional turbulence, however. His powers prove to be ineffective against the omnicidal maniac, but he does manage to summon Haruka back. Haruka tells Noein that he forgot who he was and forgot what their friendship meant. Noein adamantly denies this, and tries to argue that he and Yu are the same. Yu denounces this saying that they are nothing alike.
Between Noein’s power failing and both La’cryma and the present verifying their own existences, Noein finds himself defeated. Karasu tells Noein that no one has verified his existence, while looking directly at him mind you, and says that this is all nothing but an illusion. The sea horses arrive and tell him the same thing, again, while looking directly at him.
Noein, nevertheless, starts to lose his grip and begins to fade away to nothingness, though he vows that his vision will still come to pass.
Yu and Haruka are reunited and as they embrace, they are teleported back to their world. The Ouroboros, both in the present and in La’cryma dissolve into blue snow, as do all of the La’cryma inhabitants.
As the credits roll, we see the kids all grow up as friends. An older Haruka goes back to the church fifteen years later, saying that Karasu will show up.
