LACIE

I'm in love with this song, and been currently playing it on piano:

LACIE
OST Pandora Hearts

This is an instrumental song played on piano, but there are some version of this song which played on guitar. Sounds more difficult than which played on piano. I'll try both if I really can XD

Original soundtrack of Pandora Hearts. Ok I have never watched the anime but you should read the manga series, it's very interesting!

Oz Vessalius (main char)

Elliot Nightray
the one who plays "Lacie"

For more characters, just read the series! :p
