Okabe experiences a number of strange flashes in various world lines before waking up in bed, only to eventually return to the roof of the lab with Maho. They include running from enemy forces (likely in the bad future) and answering a mysterious phone call. He wonders if he somehow experienced Reading Steiner, and fears for the worst.
Thankfully, both Mayushii and everyone else are fine, so if there was a world line change, it was a subtle one, at least in terms of how it affected his life. Later, Amakurisu suggests Okabe give his mismatched present (a sexy red dress) to Maho, saying she’d likely be “surprisingly happy.”
Okabe doesn’t do that, but both Maho and Leskinen can tell he’s gotten close to Amadeus in not much time at all, feeding Leskinen’s hope that the AI will be able to fall in love, which would obviously be a huge breakthrough.
It seems like fate that they’d find the person who just happened to be in love with the real Kurisu. Maho just wants to know more about the side of her good friend and colleague that she never knew, lamenting that she “knows nothing”, despite the fact she is not Jon Snow.
Meanwhile, as Suzuha tries to get her eventual dad to go on a date with her eventual mother, Daru senses Suzu is hiding something, and isn’t thrown off by Suzu’s weak “it’s nothing.” What Daru learns is that Suzu did not board the Time Machine alone, but took Future Mayushii’s adopted war orphan daughter, Kagari.
In 1998, Suzuha and the 11-year-old Kagari were separated in Akiba, meaning in the present she’s a 22-year-old woman. Suzuha has been busy searching for her, with no success. Daru relays this information to Okabe, along with a request to help with the search.
Okabe quickly agrees, and when Amakurisu gets word of his task, she offers to search the vast networks she has access to in order to assist him. He pockets that offer for now, not wanting himself or Amakurisu to get into any unnecessary trouble (doing what she proposed may not be legal, strictly speaking).
After a flashback to 1998 when Kagari pulled a gun on Suzu in order to stop her from changing the future (the one in which her mother Mayushii lived), we’re back in the present, where Okabe asks Rukako and Feyris (who both grew up in Akiba) to put feelers out about a girl.
Feyris gets back to him about a “ghost with braids” asking people about a lost little girl (obviously Suzuha), but nothing concrete about Kagari. As Okabe is receiving Feyris’ call, he spots Dr. Leskinen turning a corner, but when he follows him he hits a dead end of boxes. Weird.
When Okabe returns to the lab, Daru has called someone he apparently knows who may have information for them. While waiting for this person to arrive, Okabe gets a call from Rukako with an urgent request to come meet him at his house, and no other time will do.
Then there’s a knock on the door, and who should be on the other end but Kiryuu Moeka, the sight of whom triggers all of the awful dealings Okabe had with her in other world lines. Oddly, I knew with some certainty that it would be her, partly because there was just something off about the suddenness of Daru’s connection.
Of course, this may not be a Killer Kiryuu…but from the glimpse of the hair of Rukako’s guest, it’s pretty clear her assistance isn’t needed to find Kagari…Kagari is that guest. All Okabe has to do is go to Rukako’s and he’s found her. The question is, will he be able to?
