Where can I find sheet music for Jing King of Bandits?

If you have watched episode 13 of Jing King of Bandits, in the scene where it is revealed that the Warrior of the Rising Sun is actually Miss Stir (Not to be confused with the word "Mister"), there is a beautiful piano piece. I was wondering two things: One, what the name of it is, and two, where can I get piano sheet music for it? Thanks!
