الموسم 1

Reigning class gambling champion Mary attempts to hustle unsuspecting transfer student Yumeko Jabami into a high-stakes game of rock-paper-scissors.

Mary is relegated to the lowest levels of the gambling hierarchy after her loss. Student board member Itsuki challenges Yumeko to a game of pairs.

To regain her status, Mary duels student board member Yuriko in a game of "life or death." With Mary's crushing defeat, Yumeko offers to play next.

Yumeko and Mary square off against two others in a game of Indian poker after being given a chance to minimize their colossal gambling debts.

Kiwatari continues to lose as Yumeko and Mary bluff their way through the game, but the final outcome all comes down to Tsubomi.

Yumeko must face Beautification Committee Chair Midari in an ESP card game involving Russian roulette before playing the student board president.

Deeply engaged in their deadly ESP card game, Midari tells Yumeko about her heated match against student board president, Kirari.

In Kirari's absence, pop idol sensation Yumemi offers to play against Yumeko, asking her to wager total control of her life.

With her pop idol career on the line, an enraged Yumemi seeks to ruin Yumeko after a scandalous voice recording is used as a bargaining chip.

Yumeko's odds are stacked against her when she challenges the well-funded student board treasurer, Manyuda, in an original game of poker.

Itsuki, no longer wanting to be under Manyuda's control, offers to bankroll 100 chips after Yumeko goes all-in and loses on the previous hand.

Yumeko and student board president Kirari both wager self-expulsion from the academy as Ryota becomes the key to the final outcome of their game.
