With things starting to wind down a bit, Kaito arrives at school to find a very familiar puzzle on the board, put there by Rook. Rook reveals that he has come to take Kaito to Crossfield Academy, a school for geniuses, as a temporary exchange student. As Rook meets with Kaito’s friends, we see a bit of Kaito’s past and his friendship with Rook.
Ana shows off his perception when he tells Nonoha that he wonders if Rook and Kaito truly are friends. At Crossfield Academy, Rook and Kaito go to their “special place,” a church with a maze that they couldn’t finish as children. They find a strange path there, but Kaito tries to turn back suspecting a Sage Puzzle.
Rook convinces Kaito to solve the puzzle, but the puzzle locks Kaito in when it starts. The episode ends as the Principal reveals that the puzzle isn’t a Sage Puzzle, but a banned puzzle designed to test Phi Brain children.
I question Rook’s personality. How does he go from a seemingly innocent kid to this manipulative mastermind? Was his personality always like this? That’s the only way this makes sense. If he was calculating everything from the first time he met Kaito. Oh well, I guess Rook’s personality will come out to Kaito next week.
