Episode list

Erimi Mushibami offers Yumeko Jabami and Midari Ikishima an opportunity to gamble where they choose from a selection of strings to cut, but risk having a finger chopped off by a guillotine. They relish the challenge but Ryota thinks the idea is crazy and even Erimi thinks they underestimate the risk they are taking as she has the system rigged so that her finger will be safe. The impatient Midari goes first, then Yumeko and then Midari cuts a string, but the guillotine fails to fall. Erimi explains that it is a torture machine of her family who use it to extract information. During the second round, Yumeko questions Yamato about the setup, causing Erimi to fear that her finger may also be in danger. With 6 strings cut, the third round commences, and after Midari and Yumeko cut 2 more, the risk increases, causing Erimi even more distress. Meanwhile, Kirari introduces new members to the Student Council; Terano and Yumi Totobami, Sumika Warakubami, Miyo Inbami, Miloslava Honebami, Nozomi Komabami, Lin and Ibara Kobabami, Miri Yobami, Erimi Mushibami and Rei Batsubami who are all part of the Kiari Momobami clan.

The Momobami clan announce their intention to win the election and take over the Hyakkou Academy which will be decided over 30 days by gambling. Each student will start with 1 gambling chip counting as a vote. Meanwhile, Mary warns Yumeko to be careful, even though she appears to be a distant relative the Momobami clan. Terano sees Yumeko as a minor threat and decides to eliminate her early, so Erimi invites Yumeko and Midari to the guillotine gamble which takes place in the previous episode. As the guillotine game continues, Erimi panics even more as each string is cut, fearing the game is no longer rigged. Yumeko revels in the psychological torture created by the Mushibami family's game. When only 2 strings are left, Midari cuts both strings and Erimi withdraws her finger as the guillotine falls. However, the machine is still rigged and Yumeko and Midari are unharmed. Erimi loses for withdrawing her finger and Midari is disqualified for cutting 2 Strings, leaving Yumeko as the winner. Later, Terano meets with Kirari and both reveal that they have taken precautions against losing.

Yuriko Nishinotouin collapses and loses in a gamble with Miri Youbami and Miyo Inbami. Later, Batsubami introduces Miri Youbami and Miyo Inbami to Yumeko as they have all been invited to an "election battle" and Yumeko relishes the challenge. Yuna Romotsuki welcomes them and Suzui also joins the Nym Type Zero game. Meanwhile Ririka Momobami offers Mary Saotome the opportunity to win 100 votes, and if she loses she must join Ririka's campaign. Yumeko and Suzui are advanced "Serve" chips which guarantee 24 hours service to the student council. In the first round of Nym Type Zero everyone bets 30 chips, and Miyo loses the first hand. Meanwhile, Mary realizes that she is not gambling with Ririka, but her twin sister and refuses to play. Suzui calls Mary when Yumeko collapses from poison applied when she met Miyo. Yuna says she cannot intervene as the poisoning happened outside the game. Mary sits in for Yumeko, now also playing for the antidote and an additional risk of placing their finger on a poisoned needle if they fold or lose. In the second round, Mary tells Suzui to show his cards, and after he does, she bets 100 votes.

The second round of the Nym Type Zero game begins. Miri Youbami and Miyo Inbami reflect on their past together as children where they developed their own secret communication technique. They use it to reveal their hands to each other, giving them a decided advantage. Mary instructs Suzui which cards to play, and they manage to win the round, forcing Miri to prick her finger on a poisoned needle. The third round begins and Mary bets 1 million and the others call. Mary then reveals that she knows the card distribution because Yuna used the Gilbreath shuffle, preserving the order of the cards, beating Miyo and Miri who did not pay attention to the shuffle. Miyo then instructs Miri to lose, but she collapses from the poison just as she plays the card, forfeiting the game to Mary and Suzui. Later, as Yumeko recovers after Kei helped to inject the antidote, Mary decides that she must become president as Yumeko is too addicted to gambling and risking her life. Meanwhile the election gamble continues, with Kirari amassing a large number of voting chips and is about to be challenged by the Momobami clan.

A week after the start of the Student Council presidential election, Kirari is in first place and is Yumeko in 10th place with far less votes. Yumemi asks Yumeko to perform with her as the Dreaming Creaming Sisterz and bet against the fans, but the movie star, Natari Kawaru whose real name is Sumika Warakubami, arrives and challenges Yumemi and Yumeko to a three-part performance contest. In the first round, Yumemi and Yumeko, perform a pop song and dance routine. However, Natari performs a solo song a capella and wins by 92 to 08 votes, even though Yumemi had bribed a majority of the audience to vote for the Dreaming Creaming Sisterz.

Yumemi is horrified that Natari won the performance contest and realizes that Natari must have paid a higher bribe to the audience. The next round is proposed by Natari and is called "Grin and Bear It: Death Macaron" where the test is to display no reaction when eating a hot,spicy macaron within a group of three. Yumemi guesses correctly, but Yumeko also guesses which of Yumemi's was the spicy one and the round ends in a tie. the final round is proposed by the Election Management Committee is "Soixante-Trois". The players can truthfully or falsely declare the playing cards they select as they try to guess when the real total adds up to 63 and the winner earns double points. Yumemi and Yumeko appear to not cooperate, and Yumemi is the first to pass, admitting that Natari's talents are far greater than hers. Surprisingly, Yumeko also passes, leaving Natari as the only player, but the total is over 63 and she loses, leaving Yumemi and Yumeko as the final winners.

Yumeko challenges Terano Totobami to a gamble for Student Council presidential election votes and they agree to play a game called the "Greater Good Game" presided over by Rumis Uru. The players agreeing to participate are Yumeko Jabami, Itsuki Sumeragi, Kaede Manyuda, Miloslava Honebami and Ibara Obami. The game involves choosing whether to place coins in a Personal Bank Box for their own gain, or into a Tax Deposit Box which will increases coins for all players. Before the first round, Yumeko suggests that everyone place all their coins in the Tax Deposit Box, but after the first round, there are only 20 coins deposited which means that there is a traitor and the recriminations begin. For the second round, Yumeko suggests that each player deposit a set number of coins as she has written on pieces of paper, but after the round fewer coins are deposited into the Tax Deposit Box than was agreed, possibly indicating two traitors may be working together. The players begin accusing each other of being a traitor, until Kaede is asked by Itsuki who he thinks is the traitor is, and he points to Yumeko.

Election Committee Chair, Yuna Yomotsuki gives an update on the election, naming the top 10 contenders, with Kirari Momobami still in front with a long lead, Terano Totobami in second place and Yumeko Jabami in sixth place. Yumeko suddenly challenges Kirari to a gamble, but Kirari's fiercely loyal secretary, Sayaka Igarashi, violently objects, and challenges Yumeko to a gamble for their lives. However, Yumeko changes the bet - they agree that Sayaka will bet her friendship with Kirari against Yumeko's promise to never gamble again. Kirari proposes the game of Tower of Doors and as an added incentive, Kirari proposes that the loser jumps from the 5th floor, also forfeiting their life. Sayaka and Yumeko agree. The game begins and Yumeko opens a door which leads nowhere. Then Sayaka opens a trapdoor and descends 1 floor, but defying logic, Yumeko then opens a door in the external wall.

Yuna Yomotsuki theorizes that many of the distributed votes are being held as proxies for some of the front runners. Meanwhile, Sayaka solves the trapdoor puzzles and descends to the 1st floor before Yumeko and retrieves one of the two lilies. On Yumeko's next turn she also arrives on the 1st floor. However, on the ascent, Yumeko reaches the top first, She had correctly guessed that the outer part of the tower rotated after she opened an outer door, and then used the central staircase to travel down and back up. Having lost by using logic rather than intuition, Sayaka opens one of the outer doors and jumps from the tower. Surprisingly Itsuki Jumps as well, grabbing Sayaka as she falls and they both land on a soft safety mat instead of hard ground. Itsuki takes pleasure in Sayaka thinking that she was falling to her death, reflecting on their opposing characters, the logician verses her own intuitive nature, and she asks Sayaka to be her secretary again.

Yumeko, Saotome and the other students receive invitations to a "Hundred Votes Auction". The only ones to accept the invitation are are Yumeko Jabami, Ryota Suzui, Mary Saotome, Yuriko Nishinotoin, Midari Ikishima, Ririka Momobami. Yumeko completely ignores Midari Ikishima. Rei Batsubami is the auctioneer and Inaho Yamoto is to be the Election Committee monitor. The bidding for the first lot goes quickly, with Saotome winning on a bid of 80 votes, however the unseen sponsor collected 130 votes from the bids. The second round goes to Nishinotoin, again with a winning bid of 80 votes. After the third round, Saotome realizes that Rei Batsubami is also bidding, and she forces Rei to stop bidding. However, Yumeko then suggests that Rei is both the sponsor and auctioneer which is apparently not against the rules. Yumeko then has three billion yen brought into the room, and challenges the real Rei Batsubami to an all-or-nothing gamble, and Rei accepts, removing her glasses, wig and gloves to reveal her true self.

Rei Batsubami retells when she was a servant treated like livestock by the Monobami clan and she received kindness from a lady visitor. The woman was eventually destroyed gambling with the clan and Rei swore revenge on them. Now in the present, Rei declare that she will win the Student Council presidential election and become head of the Monobami clan. After she Reveals that she is using hundreds of votes collected from non-competitive students betting on whether she would win the election, the game continues. In the next round, the competitors realize that they must continue at the risk of losing all the votes already bid and Yuriko Nishinotoin wins with a bid of 99 votes. Yumeko relishes what appears to be a no-win situation. In the succeeding rounds Yumeko quickly bids 101, winning the bids and intimidating the other players. She next bids 1 vote, winning 100 votes from Rei, more than covering her losses. The other competitors realize her strategy, and each bids 1 vote on succeeding rounds until Rei loses all her votes. Yumeko then suggests that she still has heart, and they bet everything they have on one gamble, Rei's three billion yen against the Jubami name on the toss of a coin.
