Naruto X Kakegurui AU

Basically Naruko is Yumeko's little sister.
They both attend Hyakkaou Private Academy but Naruko also pretendes to be a boy and is ninja so isn't at school much but loves to gamble. Also I've changed it up a bit so that Kokichi is also there sister and just like Naruko.
Also this is a AU where everyone who died was revived.
