That's an understatement. They have continued to shit on the few loyal fans left at every opportunity (Ethyria canceling their con appearance and the merch issues they've been having are the two big ones I can think of off the top of my head). Every time they do something like this they lose some of their remaining support, and this is a VERY expensive fuckup. There are not a lot of people who are going to be willing to shrug off hundreds of dollars being pissed into the wind by Niji.
The thing is, Niji has NEVER been unable to use Kuzuha to solve a problem before. The dude is their golden goose. I honestly believe sending Kuzuha and Kanae over here was their big plan to rekindle the EN market.
This was the point of no return, and I'm not joking or memeing about that one. This actually impacts the JP side because of the ChroNoir cancelation. I don't think that's ever happened for a ChroNoir appearance before, not for a lack of sales at least. It's going to be posted about on JP websites(some of their megafans had already flown over here apparently), Kuzuha and Kanae are probably going to mention it on stream if they haven't already, and the JP stockholders are much more likely to notice because of it. This was Riku's hail mary to keep the EN market, and it didn't even sell enough to keep the venue.
Seriously, they're fucked. JP investor meeting is coming up shortly as well, and they are going to ask questions. EN is getting folded into the main branch at some point and the v-tubers are going to be slowly let go as their contracts come up for renewal.
