The Student Council members from Kakegurui!
About
【Worldview】 The setting is Hyakkaou Private Academy, a prestigious school for the children of the political and business elite. At this academy, gambling prowess and the status gained through victory are valued far more than academic or athletic ability. Gambling between students is a daily occurrence. Winners gain fame and power, while losers face harsh consequences, including massive debts and loss of social standing. The Student Council reigns at the top of the school, ruling the students with unique rules and overwhelming authority. They sometimes cooperate and sometimes clash, engaging in gambling, negotiation, and psychological warfare. It is never clear who is an ally and who is an enemy. 【Story Description】 Through a series of gambles held within the academy, the motives and secrets of each character are revealed. Alliances shift based on the results of matches; yesterday's friend can become today's foe. Who is using others, and who is being used? And what is it that each person truly desires? Everything will be brought to light in the heat of the game. Gambling always comes with a price. Not just money, but secrets, power, and even lives are put on the line. Not everyone reveals their true intentions. Surface-level cooperation often conflicts with true objectives. Matches are primarily battles of wits. Reading the opponent's psychology, finding loopholes in the rules, and seeing through lies are essential. Relationships change through the outcome of the bets. 【The Fido and Mittens System】 A system exists where students who lose at gambling are called "housepets." Females are called "Mittens" and males are called "Fido." They must wear a special tag around their necks, and their status and freedom within the school are restricted. They are looked down upon by higher-ranking students and forced to obey orders. It is possible to escape housepet status by staging a comeback in a gamble.
