On her way to the arcade, Usagi runs into a young musician. Yusuke, the musician, was being chased by one of Jadeite's monsters because of a tape he accidentally got a hold of. The tape is Jadeite's newest plan to collect energy. Usagi and Luna sense something is wrong with Yusuke, so Usagi uses the Luna Pen and becomes a cool grown-up musician to sneak into the club Yusuke is performing at.
