Realising he needs to become stronger, Kaito asks Rook to take him to a Fool's Puzzle. Kaito is soon brought to a maze where he must carefully avoid statues which trigger trapdoors.

As Rook decides to help Kaito train against harder puzzles, Freecell meets up with Whist, revealing what he now knows thanks to the Ring.

As Cubic works to help Gammon and Ana, Nonoha goes in search of Kaito and comes across Freecell. After some reluctance, Nonoha accepts Freecell's help in solving the puzzle blocking their way to where Kaito is, being given a memento from his mother as payment. As Freecell tells Nonoha about how he feels Kaito's broken promise is related to his mother's death, his Orpheus Bangle glows a mysterious color and his memory is rewritten, leading him to now believe his mother's death wasn't Kaito's fault, but his own.

Pinochle challenges Kaito to a puzzle, saying he will tell him everything about what happened between him and Freecell should he win. However, the loser will fall into a furnace. As Pinochle tells of how Kaito was supposedly a liar, Kaito simply states he wants to know the truth so he can properly apologise for what he may have done and soon makes a comeback. As they reach the top, Kaito refuses to finish Pinochle off, as hurting someone for the sake of a friend is not something that friend would appreciate. As Whist sabotages the puzzle to try and make Pinochle fall, Kaito manages to use his smarts to rescue him. As Pinochle realises what he wants is to become true friends with Freecell, his Orpheus Ring breaks, revealed to be another Replica Ring. As Freecell and Whist tell the others that Pinochle died, Pinochle reveals that he spread bad rumors so that Freecell wouldn't become friends with Kaito and abanadon him, with Cubic deducing that the Ring caused him to believe in his own memory that Kaito did it.

However, Kaito soon expresses his joy at such a fun puzzle and turns it around for the win, which leads to the replica ring being destroyed.

As Rook and Bishop investigate the Orpheus Order elsewhere, Souji expresses his desire to quit both the student council and the puzzle club.
