The song starts at 12:34 and is kind of discordant in the beginning. It hits the part of being a real piano at around 14:00.
I am looking specifically for the song that starts at 14:00
I believe the song itself is called Rize's melody, it has a start with discord and has piano throughout most of the song and is about 5 minutes long. the name could also be Original Sorrow is this the song you were looking for?Song
