Ikigai Academy

Rei Satou is a young ex-carter and skilled con artist who will enter the Ikigai private academy as a scholarship holder. At this academy, students are ranked based on their "merit points". A system that determines who will enjoy certain benefits during their student life, and great opportunities after graduation.

Rei, being assigned to the lowest ranked group in the school, has set out to ascend in order to achieve these benefits, while planning revenge against the leader of the Saionji family, the most influential and powerful family in Japan, using the daughter who studies at the same school.

With the help of different tricks and traps in gambling games and school tests, Rei will climb to the top of the power hierarchy among the students.
