Jabami Family Dice Game[]
This gamble is played between Tsugiko Jabami and her niece Souko Jabami. If Souko wins, she continues being head of Jabami family (as her parents already died) while Tsugiko is banished from Momobami family tree. If Tsugiko wins, she becomes the head of Jabami family and Yumeko Jabami will live as her daughter, separated from her older sister Souko Jabami. Souko brought her sister Jabami with her, and her friend Kabura-san is also spectating.
The game is hosted in the family's main house. Momobami mediator is Kirari Momobami, who forced Souko to play this game as it was petitioned by Tsugiko to become head of the family. She wanted to know if her aunt had killed her parents, and she didn't deny that.
Rules[]
Kirari picks a simple game. She says that the Jabami family’s true essence lies in running gambles. So, Souko and Tsugiko won’t be players, they’ll be runners. Each player will put two dice in a cup and roll it. The person who rolls the lower number wins. The best roll is the Snake Eyes composed of two 1’s. The worst is called Boxcars and comprises two 6’s. Bets will be made before each round. Running out of money to bet with results in losing.
The bet always is the highest value asked by the players. In this game, every round was an all-in for Souko and Yumeko.
Tsugiko vs Souko[]
Tsugiko starts the gamble with 7 million yen, which Kabura guesses that she probably earned most of it selling her nephew's belongings such as home items and furniture. While Souko has only 1 million given by her friend Kabura, which makes her calculate that she needs 3 consecutive all-in wins to defeat her aunt. She is determined not to lose as the game determines her beloved sister's fate.
First Round: Tsugiko rolls out a 5. Souko got only 6/36 chance of rolling a result lower than that, and she manages to roll a snake eyes and win the first bet, accumulating 2 million yen.
Second Round: Tsugiko rolls out a 7. Souko manages again to get a snake eyes, earning another 2 million yen. The game is evened up. Kabura is rooting for Souko and wondering if she is manipulating dice results.
Third Round: Tsugiko rolls out a 4 with twin twos while Souko rolls again a snake eyes to win.
Result: Souko 8 million yen (winner) and Tsugiko 0 yen (loser)
Since she lost the game, Tsugiko has to reveal who murdered her sister and brother-in-law. Tsugiko becomes anxious. Before answering, she asks if Souko will banish her. Souko responds that she'd never do that since they're family and cries. Tsugiko believes that her niece is a kind girl, too kind to be a Jabami.
She reminds Souko that she used to show her this trick a lot to manipulate the rolls when she was a kid. In response, Tsugiko reveals that she has 8,184,000,000 yen in cash (8.1 billion) to bet on this game, Souko is shocked and concludes that Tsugiko sold the Snake-Eye Stone which belonged to Souko's mother. Now she needs to win 10 times in a row.
So Tsugiko hid her funding until now, using it to take Souko's focus away and starting a psychological warfare. She also hid her ability to manipulate dice for a snake eye as well. They start playing again and both of them roll a snake eye though Souko is severely wounded emotionally. In the next round, both missed the trick but Souko won by 6 vs 7.
The game goes on up to the point where Tsugiko has 6 billion and Souko has 2 billion yen, two more to go. Tsugiko finally tells Souko upfront that she killed her parents. She then declares that she’ll beat Souko in order to rule the Jabami family. Tsugiko rolls a Snake Eye, leaving her opponent with no option but to do that same roll. She presses Souko to make her next roll. Souko collapses. shedding blood, sweat and tears.
Tsugiko vs Yumeko[]
Later it's revealed that Tsugiko did all that trying to stop her sister's gambling addiction, even making her go to the casino with marked cards to have her kicked out, but Souko was still killed. Now she was doing that to free Souko from the Jabami family gambling addiction tradition. Also, it shows that Kirari bought the stone not for the stone itself but for the gambling that would occur with that cash. Yumeko Jabami states that this game is not fair and thus pledges to join, which is accepted by Kirari, and she continues playing for her sister. Tsugiko gets desperate and tries to claim that she already knows and Yumeko can't take the risks, while Yumeko is excited to play, they continue from Tsugiko's snake eyes roll. An even bigger problem for her is Yumeko smiling despite knowing that her aunt is responsible for her mother's death and seeing her sister collapsing.
Kabura asks if it's Yumeko's first time playing dice and she replies that it is. Still, she rolls snake eyes repeatedly. Her aunt gets furious and claims that she is cheating because she would know before if Yumeko knew how to do that trick, she takes the dice and finds grains of rice stuck to them (on the 6 side). While asking for Kirari to cancel Yumeko's last roll she was refused as Tsugiko has touched the die, she can’t know if rice was already stuck to them or if Tsugiko placed it. Yumeko starts pressuring Tsugiko who falls in her trick, and now they both have 4 billion yen.
Final roll:[]
Yumeko talks about how she always admired gambling: when it's a "contest of luck - the purest of the battles", and how it's "so much fun". Her aunt gets frustrated about how she just wanted to keep her nieces safe but failed, and Yumeko has become a "Consuming Snake" like other Jabami clan members such as her mother: "Enjoys the risk and spreads it to others" and that everything in her life is "luring her toward her ultimate doom".
Then the aunt fails the trick rolling out a 6 and a 4, next Jabami gets another snake eyes and is declared the winner.
Yumeko vs Kabura[]
Kabura admits that she was the one who lent 8 billion to Tsugiko in exchange for the Snake-Eye stone. Yumeko wants to give Kabura back her 8 billion so she can get it. Kabura smirks and demands 800 million in interest. Since Yumeko doesn't have an extra 800 million yen, she decides to do the same dice gamble with Kabura. Kabura is betting the stone on it, while Yumeko is betting herself. Tsugiko begs Yumeko to decline. Yumeko still accepts. Kabura wins and becomes Yumeko's guardian. She threatens Souko to never let her see Yumeko again. She'll only hear what Souko has to say if she hands over 8 billion yen. Later, Kabura requests that Kirari forbid any family member to loan money to Souko. Over the following years, Souko gambles until madness. Kabura brings Yumeko to the hospital where Souko is. She says that Souko being broken is all Yumeko's fault.
Aftermath:[]
This match result explains much information we already had before: why Yumeko is the head of Jabami, why she got so much money to bet and to take care of her sister, and why her sister is in the hospital - still so many years later.
