It seemed pretty clear Erika was aware of what Largo said to her in clubbing may be required
. Even if the obvious isn't, that still she was up for going along with whatever crazy nonsense he was up to for whatever reason. As if she's really a lot like him.
Which brings up another point anyway, that relationship that developed between Eirka and Largo, and then maybe Piro and ?. Perhaps asking if Piro is more like Kimiko, more like Miho, or more like neither. Or a bit of them both. Which leads into 'dying for the story' as maybe a way to try and answer some of that.
In Endgames, Miho gets to die twice, sort of. First Moh from in game directly and then Miho from out of game in the permaban. And yet, actually or in a way, neither dies. Piro is maintaining the account, so that out of game story rather continues, especially with Pirogoeth has duplicated a version of Moh so to speak, which covers in game. Then clearly, Miho was in Megatokyo when the two of Largo and Piro arrive later.
During the time between. Whatever happened with Meimi had probably finished before Endgames (perhaps the reason Miho was at the ASF trolling for whatever reasons) and that was done. But not yet potentially the main interactions with Junko, Erika, Yuki. Not all of those are stories. Or at least not in all of them did Miho die.... although we don't really know about Meimi, supposedly with Junko she only vanished, and Erika is unclear, Yuki that wasn't apparently over. Except according to the conversation with Masamichi at Megagamers, it at least put her in the ASF, which apparently going there (in whatever heath she has or not) counts as dying, maybe.
Then Miho starts playing games with Piro, Largo. Ping. Yuki. And in many ways with a lot of others. Apparently Miho has changed, in that she's playing out in Megatokyo proper with real people (allegedly that is not the way for an Analogue, out being the real thing in person) and that she has some feelings for others she doesn't usually get it's only a portrayal of the subject involved in stories. Miho feels affinity with, even bad for Ping, who perhaps absorbs something of importance (and not entirely smoothly for Ping's circuitry equivalent). Develops some apparent bond with Kimiko. At the least. Given how she's monitoring what Largo and Piro are doing and helping Erika with the Sonoda family and with Kimiko in various things like Dom's attempts at gaining control and having the radio show happen.
There is Miho impacting a lot of things all along. Finding out how Largo felt about dying in Endgames, seeing if Piro was interested in playing with Ping, telling Piro that Largo was in bad shape after that thing with Erika, helping Kimiko out of the diner... ( Well there, Miho was Ed's target, she just inserts herself into what Dom is doing at the time with Kimiko maybe.) Aside from directly interacting such as at Megagamers, there are at least indications she is influencing Erika, to help out Largo? Is she doing the same for Piro with Kimiko? We don't get much direct about why Miho is doing anything. But clearly she's more wired in about what's going on than might seem normal. It's just guesswork mostly that Miho is playing matchmaker.
Whatever was going on, it appears to reach a endpoint at the end of Ikebukuro, where it is pretty well established Erika and Largo are ExL, and evidently given what has happened (and what both Piro and Kimiko talk about to others, and how they're thought of) are PxK. And Miho takes her leave, to go off and die or return to the ASF or however that works. By using Ed as an excuse, no matter if only he thinks he killed her and Meimi feels something about it. As if it doesn't matter what story ends or she dies in, if she's gone, people forget.
Only once again, not fully is she dead or gone. Many others forget, most all, but Ping remembers. This leads, through Junko, to Yuki and Piro learning/finding/remembering/thinking of the past. So even though 'hey she's at the epicenter of a killball blast nobody could survive that even if they have previously jumped out of the middle of one in nanoseconds' dead, or cloned, or copied or however that works, she's not gone. We don't know if she was supposed to return, if Ping or Piro or Yuki are holding her back somehow from her dying or everyone else dying as is proper. But she does get returned. Because the story isn't over? Or because there's a new one already? It might be the story isn't the one everyone thinks it is either.
We do have Piro and Kimiko working on implementing Sight (Kimiko is probably unsurprisingly far more proactive about it; she's gotten some clarity and insight apparently) and also on saving Miho. Maybe that's the same thing, and how compelling things get created. There are two things that are close but different; Kimiko is more proactive about Kotone, Piro's more proactive about Miho, we could say. Seems to fit. Until through a lot of events separately, it all comes together and the story is again supposed to end, apparently. KxP is on its way again, Miho dies. But they're working again together, Piro with Kimiko's help saves her. And again, but now Miho is apparently actively trying to get the failsafe to remove her like she wants and needs, and a lot of others are also working for. But zounds, it reverses, Kimiko is in there saving Miho while Piro is helping her instead. And it works, again shoving towards KxP. It certainly seems that Kimiko and Piro are a lot alike, except when it comes to rehashing the past, although Kimiko seems to be at least willing to go along with whatever Piro needs to do. In that sense, the pair is a lot like Erika and Largo, though certainly not in the details. Then again, in this focus on the past and whatever is still unresolved fully, maybe that seems more like Piro being like Miho. Whatever it is she is.
Yet like before, Miho has gone, but isn't dead. Maybe to most unaffiliated she is dead, but not to the main players, or at least they know she's not, even if some are forgetting her, and others remember somewhat. Miho is elsewhere, no longer the active target, and giving all indications there's a new story forming. Which might very well be interrupted. Yakugashi has gathered Junpei to go interfere, another Yuki-like situation perhaps. What, that depends on a lot of things, like whatever happens next to whoever, in whatever we continue on with or move to, and when.
If whatever is going on with KxP isn't quite yet still solid, lots of things could happen. But if that is resolved, or soon is, does another story take Miho and the rest another direction totally? Does Miho just die or cease to exist, her work done? Does Ping or somebody else take over? Where does it lead, nobody yet knows, but that's another story. Well, this meta one continuing anyway.
