I know JFC wanted to know the reason where this group pic was taken from:

Just a hunch, but could they all be attending Miki's wedding? I only say so because this pic in Miki's picture thread looked like it had a connection. And with what looks like Kaori no less.

If so, hottest bridal party
ever. And I didn't think I would say that after seeing Ayaka's..
And to think, Aya's gonna be there too! Imagine the hen night
