I'm searching (and have been for the past year or so) for the following songs from GunxSword, all for piano, all the links will direct to the song on YouTube.

Paradiso by Hitomi (http://tinyurl.com/23mhue6)
Rising Tide by Shuntaro Okino (http://tinyurl.com/29yjs3x)
Opening Theme by Nakagawa Koutarou (http://tinyurl.com/35xscpl)

Thanks for any help!
