I've found the first OST uploaded on this forum, but am searching for the second volume - does anyone have it or would be willing to upload it? Also hunting for a good quality full-length copy of the OP. Would appreciate either!

I have never seen proof a vol.2 exists. If you can show me, I'd be more than happy to look into it.

Also the ed would be on the single found here: Amazon.co.jp: Youca, ?????, ????, ???? : ??????? - ??

I think there was an itunes exclusive soundtrack back in 2009... but it seems they don't have it anymore. "Remi (Ie Naki Ko) [Original Soundtrack] - Various Artists"
