Kakegurui

Synopsis

The president departs from the academy, leaving the rest of the council unsure how to deal with Yumeko. Council member Yumemi Yumemite, head of PR and a YouTube idol, announces she will be the next to challenge Yumeko. Itsuki Sumeragi, who, after losing to Yumeko, is in danger of being disowned by her father, offers to become loyal to Yumeko if Yumeko defeats the president, becomes the new president, and gives Sumeragi her place back on the council. Yumemi bets Yumeko 50 million on the outcome of an on stage idol championship competition and if Yumeko loses, Yumemi will alter her Life Schedule so Yumeko is forced to form an idol duo with her, thus losing any hopes she has of a social life or meaningful relationships, just like Yumemi.
