Does anyone know where I could find any piano sheets for
'Anata ga koko ni iru riyuu' from? (It's sung by Rie Fu.)

I've been searching for it on the net for ages, but I can't seem to find it!

Just buy the piano score book of D.Gray-Man like me...

But this score book is hard to get at the moment.

omg! Where to get that book? I want it.

D.Gray-Man Vol.2 (http://cgi.ebay.com/D-Gray-man-SHEET-MUSIC-Yasashii-Piano-Hikigatari-2-NEW_W0QQitemZ310159240604QQcmdZViewItemQQptZLH_Def aultDomain_0?hash=item4836ee6d9c&_trksid=p3286.c0.m14)
I must say that the score book isn't very good, it really disappointed me. They skipped like the a lot of music in Gekidou, very bad intro.
But if you're a fan like me, than it's a wanna have item =)

Woah, you're definately right about the fact it's hard to get at the moment O.O
Thanks anyway!
