They're the Band of 14 Devils!! - S1.E4

After some debate, Minami reveals that the club's official name is "Game Creation Club (Provisional)." While trying to avoid having to play the "Quest for Porn Mags in Space" board game that Roka created, the Kazama Party gets ambushed by the "Band of 14 Devils" (minus two for personal reasons). Despite his best efforts, Kazama and his friends are captured, though Ataru escapes to warn the Game Creation Club (Provisional) about what happened.
