Due to life intervening, we have a double feature!
In the first episode, we got some heavy Amrou focus because Yuugure writes herself out of the show for an episode due to playing bait for those sister robots of hers.
Thus, Amrou and Akira have a day to hang around before making an after-hours raid on the library, enabled by the scholar (who seems like a new party member). I wish they talked about things with substance, but it’s mostly fluff until we get to the library. The infiltration is reasonably amusing, but evidently the pair doing it trip some kind of alarm, pulling the librarian away from her hot night with the scholar.
As they investigate her private sanctum, finding both the book Amrou’s parents wrote and a book by Towasa about the Life Compensation System, the Librarian arrives, flipping into whip-wielding psycho dominatrix mode, because nobody working for OWEL is mentally well. She unwisely decides to whip into a standoff with Amrou when Amrou arms herself with an oil lamp, causing the lamp to get broken and set the library on fire. The pair see that the books that are their targets can still be grabbed, but likely only one.
Naturally, Akira chooses Amrou’s book over his lead. As they meet back up with the scholar, this turns out to not be all that catestrophic, as the banned picture book seems to tell a mythologized version of the AI War, with people with “special blood” (the recipients of Towa’s Life Compensation system?) becoming the source of a conflict ultimately put down by twelve angelic sisters (Presumably the Outside Series).
Shortly after, Yuugure boards the train to Tokyo with them and is welcomed back. They end up interacting with another crazy Ehlsea group, in this case an insanely boisterous man, a super quiet woman, and their two kids. This distraction forcibly inserts itself as it seems that the adults are a bit on the rocks due to the man cheating a decade earlier and wanting to try to make the scenario right. The gang is basically begged into helping, even though it’s unclear what exactly they’re meant to do.
While Amrou gets involved with that, Akira and Yuugure are confronted by Yuugure’s sisters. The nun sister talks matters down to a truce while on the train, while Akira asks after Towa with more of her same-face creations. They reveal that while one of the reasons they were after Yuugure was just to keep tabs on the insanely powerful Outside Series, the other reason was seeking the whereabouts of Towasa, like Yuugure should already know.
And that’s basically where we end the episode. It… does not bode well for Yuugure. There are a few answers she could give that won’t cause a rift with Akira, but I want to emphasize the “few” in that, and more likely we’ll be getting at least a partial episode of not trusting her. Obviously the angry one and the priestess one can’t be trusted either, since they’re tied to OWEL and we know what stable and reasonable people those are, but something had to at least impede Yuugure’s progress towards desired marriage.
Aside from that, I’m not sure how the family on the train is going to amount to much, I guess the boisterous dad of the lot says he works as a guard so maybe if they mend his Ehlsea he’ll pretend to not see them later? Hard to say.
