Taking them to a hidden cave under the pretense of helping them find Raetsel, Regina reveals herself to be a Master Brain and traps Cubic and Ana in a Fools' Puzzle, in which they must travel via canoe across several containers whilst making sure they end up with equal volumes. Cubic makes some progress with his calculations thanks to Ana, but Regina keeps interfering with their progress. Luckily, Cubic's robot, Iwashimizu, arrives and uses a stalactite to bring the water up to the right level, solving the puzzle and earning their next clue. As Kaito's group finally arrive only for the puzzle to be already solved, Herbert is seen talking to Enigma.
