The guitar melody over the hollow instrument feels almost happy at first. But then that acceleration and big chords into the beat certainly feel like it moves into a boss track. I love the beat you bring in for the second half! The chords have a somber and despair-inducing quality which contrasts the upbeat drums to create both a sad and energetic boss theme. Your description implies that you were going for a character theme with a complex mixture of emotions and I think you did that well. You also did a nice job taking us through the pre-battle, battle intro, and meat of the battle. Good work and thank you for sharing!
