S3·E21 Kaito, You Lose

As Souji, Cubic and Ana meet up with the Orpheus Order to learn what they can about Orpheus, Rook, who has received an Orpheus Bracelet from Orpheus, challenges Kaito to a puzzle in which they must race against each other in roller coasters. Rook reveals that Orpheus' ideal is to surpass the gods, stating that he has seen the future that Kaito will fail the puzzle. However, Kaito's determination to save both of them proves Orpheus' future to be false, shattering Rook's resolve. Near the end of the puzzle, though, Rook reveals that the track is designed so only one can escape safely, sacrificing himself to let Kaito escape. This leaves Kaito more determined than ever to become a Phi Brain and defeat Orpheus.
