The azure stamina song, one of the hardest ranked 5 stars in my opinion.
This song is from a game called Trails to Azure, I highly recommend playing the series since it is one of the best rpg game series of all time.
The streams and trills in this song make it a killer for your arms if you aren't careful, so practice stamina control.
