Title: Kakyou
Album: OST 3 Yuri Heika Seitan Kinen! Omoide no Album
Anime: Kyou Kara Maou
Composer: Yoichiro Yoshikawa
Instrument: Piano is the target

It's a romantic piece, hopeful and dreamy. If interested I can pm you the mp3.

Also, there is a second pure piano solo that I have requested in case a simpler song is more towards your taste as Kakyou does have strings. http://forums.ichigos.com/showpost.php?p=439068&postcount=734

Thank you so much in advance!
