Student board member Itsuki challenges Yumeko to a game of pairs. Rumored to have never lost in this game, Itsuki lays a shrewed trap agaisnt her.

After a monumental outcome, Yumeko receives a cryptic file form the student board. Meanwhile, a card game for those heavily in debt commences.

A nervous Suzui serves as dealer for Yumeko's deadly duel with Midari. Meanwhile, student board member Manyuda summons Mary for a surprising proposal.

Desperate to regain her status in the school hierarchy, Mary duels student board member Yuriko in a game of "life or death" as Yumeko looks on.

Yumeko and Mary pair up for a game of Indian poker against Kiwatari, the class bully known for manipulating others through fear and intimidation.

Yumeko agrees to go up against the Beautification Committee Chair in an ESP card game involving Russian roulette.

Unaware of her new school's ways, transfer student Yumeko Jabami is offered a high-stakes game of rock-paper-scissors against her classmate, Mary.

Having lost her initial buy-in against Mary, Yumeko raises the stakes even higher by reburying into the match with an extremely large bet.

Although able to repay her losses, Yumeko chooses to remain in debt in order to qualify for an official match with the student board president.
