not exactlly anime, but not far from it i guess.
Piano pieces from Final Fantasy - Advent Children. there's an album out there where you can find 13 versions of the main tracks in piano. I perssonally sugest "Tifas Theme", "Aeris Theme", "Fighting", and "Main Theme". I've transposed tifa's and aeris to guitar (of course omitting some notes that arent possible to play due to the obvious differences in instruments
). hope you like them as much as I do
