Kamado Tanjiro no Uta, from Demon Slayer, music by Go Shiina, piano arranged by Animenz, played by Richard Yang on Yamaha N1X with Garritan CFX VST.
This is one of the few anime songs that I had actually heard of before I learned it, thanks to my kids who watch Demon Slayer. Although the piece is overall on the easier side, there are a few elements that are challenging, such as keeping a slow but steady pace in the beginning, and the 32nd runs.
As with all of my performances, I have my own interpretation, so the tempo, dynamics, etc may feel quite different from the original recording. Simply put, I play the way I like it.
