Kurara Kurokura

Plot("Kurara is first seen in the monitoring room, along with Inaho Yamato, Rumia Uru and the other observers, while they discuss Scumcoins. Kurara then heads off to oversee the gamble. As soon as Rin Obami, Mary Saotome, Nozomi Komabami, Ririka Momobami, Ibara Obami and Mary's friends have arrived, she explains the rules of the game, which is one suggested by Rin and called War. During the game she simply stands there and announces the results. At an unknown point in time, Rin and the imposter kept the real Kurara away from the scene, most likely by kidnapping, but the exact circumstances are unknown. The Impostor then dressed up as her. During her time, where she was disguised as Kurara, she most likely acted and looked the same as the real one. That must be the case since we see her around other election observers, who don't seem to notice anything strange. What happened to the real Kurara is yet unknown. She most likely got rescued by Runa Yomozuki after the game was over. Rin and the imposter laughing at the others Because Ririka tricked him and his lies got exposed, Rin ends up losing with -269 points. Ririka questioned Rin, why he hasn't cheated at all. He then reveals, that the gamble only counts if an election observer is present. Everyone is shocked to learn, that it isn't the real Kurara Kurokura standing in the room, thus the match doesn't count. He then goes on how the election doesn't really matter, since Kirari Momobami is sure to win anyway. But Ririka had a voice call with Runa, head of the election committee, running the whole time. Runa then storms in and declares the match as valid, tossing Rin out of the election. The imposter is visibly nervous and starts to cry, most likely worrying about the punishment. Runa is angry and calls her a big faker. She is then seen being dragged away by Runa. The real Kurara and Runa then gang up on the imposter and threaten to punish her immensely. The imposter is extremely scared and cries uncontrollably. But actually Runa was just kidding and presents her with an observer frog-themed hoodie. The two laugh at her for being so scared even though they were just joking. Despite what she had done, Runa must have realized that the imposter acts well as an observer and appointed her this duty for real. The real Kurara finally appears during the Rock Paper Scissors Poker tournament, working as an observer. She wears a sash with the phrase "I am real" on it. There she explains the rules to everyone. She hands out the cards and declares the winners of each round. She is excited to open the second batch of games. Kurara is also confused by Midari Ikishima's weird behavior, especially when she gets excited becauseYumeko smiled at her. Kurara keeps on happily announcing how Miyo Inbami beats Mary every round, so that Mary even suspects her to work with Miyo for a moment. When Mary asks to use the bathroom, Kurara tells her she should rather hold it in. She is also naturally shook when Miyo takes a poisonous pill and threatens Mary")

Hyakkaou Private Academy("Gambling at Hyakkaou Private Academy is governed by the student council. It is known that the student council members use their powerful influence to collect money from students of Hyakkaou Private Academy. Payment of it is called a "donation", where it is optional but is practically obligatory. Hyakkaou Private Academy has a ranking system which can be given to students that have failed to donate to the school. Those under 100 of the 3,000 students or who have accrued a massive debt that they cannot pay are recognized as a "housepet". If a student is a male, they will be called "dog" (pochi), if the student is a female, they will be called "cat" (mike). The hierarchy in Hyakkaou Private Academy is absolute where no student can go against it, and if they do, they will await the student council's reprisal. If the student wants to rid themselves of their "pet" status, they have to donate but it will be impossible if the student has either a massive debt to pay off or no money to pay their way out of their status. The hierarchy is described as a perfect dead end which is known by the students as something that is extremely hard to escape. Hyakkaou Private Academy is an educational institution where students from powerful families in the political and financial world attend. As the school that Yumeko Jabami, Ryota Suzui, and Mary Saotome go, it is also the main setting in Kakegurui. Hyakkaou Private Academy was founded 122 years ago in Japan and for many years since its inception, was a school where students from powerful families in the political and financial world attended. It is a school where students are not evaluated by studies or sports, but through the social status they possess. This is because studies and extracurriculars are not necessary for people who are destined to have power over others. For them it is important to be well versed in tactics, reading an opponent, and the strength to grasp victory which are abilities they have to prove and obtain through gambling. As shown during Souko Jabami and Kabura Tsuibami time as students, the school building’s interior prior to Kirari Momobami’s takeover was of a much older fashion, resembling a more traditional Japanese school building than the current modern-western design. As shown, students still gambled using the rooms of the school after classes. But gambling itself was also shown to have been less rampant during this time and was shown to be seen as more of a pass time or a after school activity, albeit the students themselves still used real money. Two years prior to the start of the series, Kirari Momobami upset school tradition after winning a gamble from the former student council president, creating the Housepet system to reinforce an already existing caste system. The pet system consequently increased discrimination among the students: those who weren't good at gambling were oppressed, seen as just housepets and were constantly bullied. Meanwhile, the victors were praised. Hyakkao Private School has a not very strict dress code, since the institution doesn't exactly focus on good grades and good physical performance; for example, Erimi Mushibami and Yuriko Nishinotoin don't even wear the standard uniform; also, apparently it is not mandatory for the student to wear the uniform made to their sex, as Rei Batsubami wore the male even though she was a girl. Housepets, formally known as students with uncooperative tendencies, are students who have fallen into the bottom 100 contributors of donations to the Student Council at Hyakkaou Private Academy, thus losing their general rights as independent humans at the school. The Student Council announces rankings on a regular basis and has heavily tied it to the state of gambling at the academy, covertly using the systems to control individuals with power through the amassing and centralizing of debts. They are also responsible for enforcing debt payments across students to further solidify the system. To further exploit, coordinate, and manipulate the Housepet situation themselves, the council often schedules events such as Indian Poker, Grand Tournament, and the Bloom Festival. When a student becomes a Housepet, they are required to wear tags that signify the status to others. These students are often referred to as "Doggy" or "Kitty" ("Fido" or "Mittens" in the dub). Once a Housepet are subject to abuses, taunts, and are required to follow the demands of other non-pet students. Some of these requests range from mild chores to extreme scenarios such as sexual gratification and emotional abuse. Each Housepet is given a single chance to challenge any other student in a match, known as an Official Match, often in large bets that are last attempts at escaping their outcomes. Many times these are played against the Student Council themselves as a way to gain not just recovery from debt, but also standing among the student body.Aside from Official Matches, another method a house pet could use to escape from their low status is the “Special Student Council Payment System”, where by paying one million yen, a house pet can instantly be free from their status. However due to the unwillingness of most students to gamble with them, house pets themselves are unable to acquire such money. The uniform consists of a white button-down long-sleeved shirt and a red blazer with gold buttons. The boys wear a black tie and gray pants, while the girls wear a black cross tie and gray skirt. As the dress code appears not to be so strict, some students use it in different ways: Jun Kiwatari doesn't wear a tie and leaves his blazer open; Ibara Obami wears a tie, but leaves his blazer open with the sleeves folded down to below the elbow and the pants are also folded down to below the knee, she also doesn't wear socks; Sachiko Juraku was not wearing a cross tie, but a regular tie. When it comes to the women's uniform, there is no mandatory type of sock for them to wear, as many girls have different types. For example, Runa Yomotsuki wears striped socks and Itsuki Sumeragi wears black socks with star prints on the side. Skirt size also varies; most wear it mid-thigh, but a few girls like Nanami Tsubomi and Sayaka Igarashi wear it just above the knee. Some students like Kurumi Kurume and Midari Ikishima wears a red sleeveless vest instead of a blazer; in fact, the first one doesn't use a crossed tie and leaves the shirt open enough to reveal a good part of her bust and bra. Chitose Inui is another example as she uses a red bow. During the summer, the long-sleeved shirt and blazer are replaced by a short-sleeved version. Kirari wears a version with the bishop sleeve shirt cut off at the shoulder . "Non-cooperative students" (ie, with debt they cannot pay) are always wearing a pet tag around their neck. For students with very high debts, as it was with Mary Saotome and Yumeko Jabami, they should pay it back with their own lives from a Life Plan (人じん生せい計けい画かく表ひょう Jinsei Keikakuhyō ): a booklet that was given to these students containing everything that would happen in their lives from the moment they graduated. If that student could pay his debt earlier, the life plan is canceled, but if not, everything written in the booklet would happen in real life; since the student council would use their family connections. However, Mary vehemently protested this insanity; as outside the school, her life was hers to live and not the plaything of the president or council.")
