S3·E3 Even So, I'll Believe

As Raetsel transfers into Root Academy, Gammon spots Jin behaving rather oddly, uncertain whether or not to believe either Kaito or Ratesel. Later, a Master Brain posing as Jin appears before Kaito, challenging him to a Fool's Puzzle in which he much navigate a sliding puzzle maze within a time limit or else fall to his death. As Kaito comes close to solving it, the fake Jin blows out one of the rooms, preventing him from reaching the exit, as well as tilting the maze. However, Kaito manages to take advantage of risky nature and reach the maze's goal in time.
