The Angels have a lost technology that, when activated, will destroy the universe. The only way to shut it down is to play seven-person, three-letter shiritori with seven laps. Milfeulle is not very good at this game, but Forte knows a turtle which can turn back time an hour. The Angels and Twin Stars continue to mess up until Maribu tells them to stop after calculating that the odds of winning are 23 trillion to one. Maribu instead brings out a bird, which combined with Forte's turtle, allows them to go back to any time. Everyone warps back in time to stop the inventor from building the lost technology in the future. They succeed, but find out that they cannot warp back to the future.
