Regarding the new song (currently untitled), Mizuki commented, "Team Mizuki will be welcoming Nishikawa-san. It will be a hot rock sound so please look forward to it! I will do my best so that everyone will love it like our previously song."
Meanwhile, Nishikawa said, "With this song, I hope to cause a further revolution with Mizuki-san and liven up the second season of 'Kakumeiki Valvrave'. Where this story will go. As an anime fan myself, I am looking forward to it."
The ending theme will be ELISA's "REALISM". She sang the anime's second ending song, "Soba ni Iru yo".
