Claire and Yatou find Shuuichi and Chihiro (and Chihiro’s wallet), then return to the hideout where there are finally formal introductions of the remaining members. One of them, Isao, is a mild-mannered plant-lover who just happens to remember Shuuichi playing with friends at Yamada Cram School.
Shuuichi just happened to dream of the school, but woke up before he met any of his classmates. And yet Shuuichi insists to Isao that he was the only student at the school, which aside from being very odd (wouldn’t he just have a tutor?) reinforces the idea that his memories have been supremely messed with.
Claire is naturally suspicious of Chihiro, and doesn’t believe she doesn’t remember anything about the battle after she and Shuuichi were smushed. This scene is akin to your typical high school drama confrontation between romantic rivals, just as entering Shuuichi is akin to sex.
Claire insists she’s “irreplaceable” as Shuuichi’s partner, but Chihiro speaks with some authority that the two will never “become one” before walking away. Claire’s fear Chihiro might just be right—and dread of the loneliness that could result from that truth—likely conspire to keep her from taking a shot at Chihiro.
On the way home for the day, Claire brings up Shuuichi’s “experience” with Chihiro, including asking straight up if she was “better” than her, and even half-jokingly proposing real sex with him as a means of reasserting their exclusivity. What’s so heartbreaking is that the truth is, from a combat perspective, Chihiro was better.
Because Chihiro and Shuuichi shared the same goal in that moment (perhaps nothing more than a desire to survive their smushing), she was able to exact a transformation—and a closeness to Shuuichi—Claire hasn’t come close to achieving. She can say “you and I are one” all she wants, but Shuuichi and Chihiro really were a single entity.
As is expected of such a non-confrontational fellow, Shuuichi remains passive in this brewing love triangle for now. He seems destined to continue having women slip into his zipper as long as he ends up in situations where he needs to become stronger. Claire is right on one count: Shuuichi needs someone around to spur him to decisive action.
Who is best for that role depends on what he wants his role to be. And whether it’s encountering his classmate Abukawa burying a dog that was (allegedly) run over, or fixing Mifune’s bike, he wants to use his power not for himself, but to protect normal, powerless people like them. (Incidentally, Ikeuchi is spying on him when he’s with Mifune, and concludes he’s an inveterate womanizer.)
That night, Chihiro calls Elena, using the number she found on Shuuichi’s phone. She’s desperate for answers about what happened to the two of them, and Elena generously explains that what happened is Shuuichi’s special power, and how only someone who shares his goals can fully join with him, as Chihiro did.
Chihiro, it turns out, not only remembers the entirety of the battle while she and Shuuichi were joined, but was privy to all of his memories, many of which were full of “shadows,” or unnaturally erased details memories. Whether it’s the fact he had classmates at cram school, to the fact he and Elena were clearly in some kind of relationship, Chihiro is new link to memories Elena thought were lost.
I’ll just add that this episode was full of great dialogue between seiyus Hanazawa Kana and Ichinose Kana, whose voice many compare to a younger Hanazawa.
Chihiro could glean from those memories that Elena wasn’t a bad person, and pleads with her to join them. She’s assuming Elena is that same not-bad person, and it’s clear she isn’t; people change. Still, Chihiro’s revelations could pave the way for a possible redemption of Elena, provided a lot of conditions are met.
The next day the Weak reassemble and set out in search of more coins, with Sayaka noting the pattern of their locations indicates the path of the alien ship, which is their ultimate goal to 100 coins. Elena, meanwhile, told Chihiro “someone” (either her or someone she’s aligned with) already has 100 coins. So the Weak certainly have some catching up to do.
Speaking of coins, Claire ends up taking her own, which she told Shuuichi she’d never use on herself, out of its hiding place and staring thoughtfully out the window. She may not know for sure what we know about the extent of Chihiro’s connection to Shuuichi (or how much “better” it was), but I’m sure she suspects the worst, and might feel like she’s suddenly being left behind. Things continue to get very messy indeed.
