It kind of makes sense though since those 4 are the "hard-drinking party girl older sisters" of the group and groups have had sub-groups since at least Onyanko Club in the 1980's.
I know Hot Stage is where all the big groups get to perform but it's a PITA to get to if you just want to watch one group in between a bunch of others. Moving ANYWHERE is a PITA at Tokyo Idol Festival with the heat and all the stages spread out so far from each other. I'm worried about them being the opening act since PASSPO is gonna try do ALL THEIR SONGS on New Year's Day (and they actually sing, or will they?)! Looks like it might end up being the longest concert I'll have ever gone to for one group if they do. Better get those hi-fi ear plugs because tinnitus isn't something I want.
Off topic: Seems this forum (and a lot of others) aren't that into Pla2me (or any of the other BiS related groups) based on how much is posted but they're missing out! Looks like their "one-man" is the dame day as the Idol Museum event in Akasaka. At the very least, I need to go to one of their release events that have a mini-live just like last time because it was awesome!
Anyway, looks like I have to mail out this thing for TRACKS tomorrow if I want a chance at getting some "signed goods" from a member but seems I can only choose one! Decisions, decisions! Mosishi? Anya? Yukkii? Sakoti? Makocchan (because this would be the last chance)?
Despite seeing Hacchake-tai a few times, I still don't remember Yukkii's name that she uses in the group. I know that Moshishi is "Gen", Naomi is "Zaian", and Nachu is "Nasu" though.
