ButchxBelladonna- Green Music

First, Belladonna is Buttercup!

According to the version of Fusion Fall, Buttercup loses her memory after losing a battle with mojo ... is hosted by GangGreen Guang ... is with them it becomes a rock star called Belladonna.
The drawing depicts my version of anime to this passage: Illustrates Butch using their power "Music" to recall the Belladonna is your true identity. Ace in the background, looks scared to attempt Butch to end with his band.
