So, hang on, I want to take a really hard look at the history here. My understand of things goes something like this:
At some point in the last couple weeks Hijiri observed the Pleiades fighting a witch, and was then contacted by Kyubey, who informed her that she was a clone created by Niko while helpfully omitting the "how" and "why," maybe even implying some horrible shit without actually saying anything explicitly. She contracted, making a wish to the effect of becoming connected to the Pleiades, which is why she has their powers, and planned some degree of malicious action against them, or perhaps just against Niko.
The likelihood of her making the same general sort of wish as she did in canon, which is necessary in order to have the Pleiades' powers, and not planning malicious action against them given that she had to talk to Kyubey in order to contract and never spoke with the Pleiades between contracting and today... I'd be disappointed in Kyubey if she wasn't planning malicious action against the Pleiades, I mean, how could he not engineer that at that point. It certainly fits with how she reacted to Niko. Her getting this info from Kyubey is both canon and necessity -- there is no other actor that could have provided the "you're a clone" information to her.
She then ran into Airi and recruited her, figuring she'd make a useful, if batshit crazy, pawn. Then came yesterday, when very suddenly half of the Pleiades left town. It was too good an opportunity to pass up, she had to do something while they were away, or risk Airi deciding she was too soft. We know what she's done since then, if not necessarily what she's thought -- and I'll note that following her conversation with Niko she's acted very, very differently. Her desperation has to be genuine -- she's neither sufficiently badass to fake it nor would its absence make any sense assuming that Kyubey implied Bad Things about how + why Niko created Hijiri.
TL;DR: Hijiri drank the QB's kool-aid.
There is zero evidence at this point to suggest that Hijiri is actively out to screw over the Pleiades as a whole. For one thing, she didn't get to that point until the Freezer reveal in canon; for another thing, whatever story Kyubey got her to believe, it clearly didn't jibe with what she ran into speaking with Niko.
So, for a moment, let's consider the repercussions of letting Hijiri go. The main concern is that this will damage relations w/ the Pleiades. I think we can throw that out safely.
First and foremost, it is, in fact, understandable that we did not expect her to suddenly pull out fast travel / teleportation when she made no use whatsoever of it when we were chasing her the first damn time. If she'd fled by other means we would've contained her, if she'd attacked us we would've contained her, etcetera. We, the thread, didn't see this coming. If we had we might have tried to do something about it. Somebody will disagree with that statement, I'm sure, but the fact is that the last two votes did not anticipate this action.
Secondly, we have no means of containment which is not excessive. Yanking her soul gem is excessive -- whatever her previous motives, she has changed since her conversation with Niko... more than that, I think we have to ask whether Niko would have condoned us trying to hold Hijiri with that sort of method. I don't believe she would have -- she wanted Hijiri let down from the cocoon of ribbons/paper/etc the first time, I just... I don't think Niko would want us to harm Hijiri, period. Given that, the question of "legality" resolves itself favorably -- the victim doesn't want to press charges, so to speak. If this were Oriko back in book 1 I'd be voting to yank her gem and maybe do more than that, but Niko pretty clearly isn't interested in Hijiri coming to real harm, and, I reiterate, we have no way to hold her currently that doesn't bring her to real harm.
I think based on that we can formulate a vote which lets Hijiri go without meaningfully harming relations with the Pleiades just by being honest about the issues we're having with this vote. Any action that we expect would be effective at holding her is excessive, and we weren't prepared for this because we didn't expect it to happen, at least not the way it did.
I'm really hoping this is gonna be my final vote here.
[X] Let Hijiri go.
-[X] ... unless Mami can stop her with ribbons, in which case, emphatically do not stop Mami from stopping Hijiri with ribbons.
-[X] Reply to Hijiri via telepathy: I think you'll find that the "can's" and "cant's" of the world are very different from how Kyubey would imply them to be. Lying by omission has been the majority of his job since before the dawn of history, not that he'd characterize it that way.
[X] Have Mami snag Anri.
[X] Telepathy the Pleiades, Sayaka, Mami: Hijiri, it would seem, has the entire powerset, including teleportation and fast transit. Why she didn't just break that out the first time you have no idea, but you completely failed to anticipate it and you had no way to stop her without excessive force, which... you don't think Niko would have wanted. Anri is caught and has the clear seed with her.
What we do after this is in question. We need to talk to Anri, but we'll also want to discuss Hijiri with the Pleiades -- what does Niko want done, we're pretty sure Hijiri's actions & her perception of Niko were feat. QB's kool-aid, etcetera.
