Hyakkaou
Hyakkaou is a fictional high school featured in the manga and anime series Kakegurui. The academy is known for its unique and highly unconventional educational system, which revolves around gambling. Students are encouraged to participate in high-stakes games, and their social standing within the school is determined by their gambling prowess. Those who excel in gambling are afforded prestige and privileges, while those who fall into debt become "life pets," essentially servants to the winners. The school's curriculum includes not only traditional subjects but also specialized gambling courses and etiquette. Hyakkaou Private Academy has a strict hierarchy established through these games, creating a competitive and often ruthless environment. The student council holds immense power, overseeing all gambling activities and enforcing the school's peculiar rules. The series primarily follows Yumeko Jabami, a new student whose insatiable desire for the thrill of high-stakes gambling disrupts the established order of Hyakkaou. The academy's opulent and extravagant setting further emphasizes the wealth and influence of its student body and administration.
