Haruka starts to watch old home movies of her grandmother spending time with her. This causes Haruka to go out to the mailbox to see if she got a letter from an old friend from years back. When Haruka moved away, they promised to write to each other,though fell out of the habit. Even though Haruka knows that there probably won’t be anything, she decides to check anyway.
As she’s checking, she is met by Koriyama and Uchida. The three make pleasant conversation and discuss the nature of memory. Koriyama says that in his old age, he’s forgotten things. This causes Haruka to panic as she doesn’t want people she’s close to to forget her. The three part ways as Haruka receives a phone call from Ai, telling her that the group is getting together to hang and they want her to join.
We learn that the events of last episode have been swept under the rug and written off as a mirage. Of course, the kids don’t buy it. The plot point reminded me of It, how only the children’s imaginations allowed them to accept things beyond the realm of known science and how it was up to them to stop the crisis.
As the group of kids walk around, Haruka thinks she sees her old friend. She runs up to say hi and the mother greets her warmly. While the mother is all too happy to reconnect with Haruka, the girl later admits to her mother that she doesn’t remember Haruka. This bothers Haruka quite a bit, her friends try to cheer her up, but she tries to play it off like it was nothing. Isami buys into the facade, but Ai is quick to realize that she’s covering it up. Yu offers to go talk to her, and Ai agrees, saying that having all of them try to comfort her would only make things worse.
Meanwhile, Uchida tries to put a stop to the magic circle project. She talks her boss into trying to warn the head of the operation about the possible danger. Her supervisor agrees, but his arguments fall on deaf ears as the head wants to use quantum mechanics to make a profit. He doesn’t really go into detail about how that’s supposed to work, but it is still a pretty dramatic scene.
Kosagi confronts Atori and demands to know what he’s up to. He pleads ignorance, but Kosagi isn’t buying it and proceeds to beat Atori into submission. It’s only when Tobi intervenes that the curb stomping is brought to an end. Tobi convinces Kosagi that nothing is going on and Kosagi leaves, prompting Tobi to disappear as well. As Atori slowly gets to his feet, we see his eyes bug out as he begins to laugh giggle maliciously, showing us that his original personality is beginning to re-emerge.
In La’cryma, Kuina asks the dragon knights to give him permission to gank Haruka from her dimension. The other knights initially deny this request as it would take all of their energy, rendering them defenseless. Kuina challenges them to come up with a better idea and they draw a blank. In Kuina’s mind this gives him the authorization to proceed with his plan.
In the present, Yu talks to Haruka and she confesses that she’s having a harder and harder time remembering her grandmother, even though she hasn’t been gone that long. Yu comforts her by saying that sometimes it happens and that there are other things that they remember, such as the time they first met. With Haruka cheered up, the two go back to Haruka’s house to meet up with Ai and the others.
As the group is having a good time, the kids still marveling at La’cryma technology, Haruka finds herself surrounded by blue snow. Tobi notes that there is a very unusual dimensional disturbance. Elsewhere, Karasu picks up on it and rushes to help Haruka.
Haruka starts to vanish and Yu attempts to save her by grabbing on to her. Karasu appears and attempts to use his ropes to latch onto Haruka, but the two vanish before he can get a grip. The episode ends as Atori laughs maniacally at Haruka’s disappearance.
