Tôru Naomura

This live action manga adaptation follows Yumeko, a student transferring into the super elite Hyakkaou Academy, a school for the children of only the most wealthy and powerful. In this unconventional school, your place is decided by high stakes gambling, where students bet their fortunes against one another. Winners rule the school, while losers are forced to act as slaves for creditors.

Hyakaou Academy is an institute where the academic ranking is based on the pupils' gambling winnings. Yumeko is new to the academy. Her pretty enchantress looks are only surpassed by her voracious appetite to gamble it all and win it all. (imdb)
