In the middle of an overgrown Shibuya crossing, Niragi challenges Arisu and Chishiya to a game. But then, the King of Spades arrives.

For their final game, they’ll need to survive three rounds of croquet; but before they can get very far, the Queen asks them to sit down for some tea.

Aguni has one thing on his mind; to find and kill the King of Spades. He’s joined by Arisu and a determined high schooler named Akane Heiya.

Usagi will have to change the hearts and minds of the cynical players on the Queen’s team. At the Supreme Court, Chishiya meets the King of Diamonds.
