Mary chooses to face Sakura Miharutaki in a gamble. In the first match, a treasure hunt game where she must solve riddles and find hints hidden in treasure chests, Mary teams up with Tsuzura and Yukimi, putting up a fierce fight. However, she falters in the face of Sakura's overwhelming strength. It's Tsuzura who encourages the wavering Mary. For the second match, Mary prepares for a one-on-one gambling battle called the "Dice Nim Game," with Aoi Mibuomi serving as the dealer. This game demands pushing one's thinking to the absolute limit. Mary quickly finds herself in a pinch as Sakura, who skillfully reads her opponent's psychology, exposes her cheating. Facing Sakura's seemingly invincible strength, defeat appears inevitable… but high school gambler Mary Saotome rises to a new stage in this battle!
