Black Heaven, and by extension the ultimate weapon, is not at full power because it is missing its keyboardist Watanabe/Joseph. In an X-Files homage, the 3 stooges Kotoko, Eriko, and Rinko go to America to find Watanabe's grave and investigate an UFO incident, encountering special agents that are doubles for Scully and Mulder pushed into a giant hole created by rival aliens who had stolen Watanabe's corpse. Yoshiko reveals how Watanabe really died, not in a romantic mysterious highway assassination during a visit to America, but in a freak incident when he innocently raised his lobster-injured middle finger at a gangster. The band finds an abandoned office space to practice, but find that they still need a keyboard for a key portion of their signature song; Layla offers to fill in as the new keyboardist.
