"Bonus Track" is the sixteenth chapter of the Season 2 manga and the thirty-fifth chapter of Rose Guns Days overall.
The story returns to the 2012 interview between Julie Hayashibara and Jeanne Amakawa. Wayne Uedera is revealed to be mediating this meeting. As the interview wraps up, Julie returns to her car, being driven by Wayne's grandson Toratsugu Uedera. Jeanne promises that the next they speak, she will discuss the events of 1949, which transformed Primavera into the violent organization known as "Harukaze."
