People are gambling crazily, their charm is super S

Private Hyakkaou Academy, a cruel academy where classes are divided based on money and gambling skills.
A girl who was set up by her classmates and lost a large sum of money and was about to become a domestic animal obtained a gambling system. Regardless of whether she won or lost the gambling, she could gain experience points and draw cards to obtain special abilities.
System: Congratulations to the host for drawing the special ability card "Charm". After using it, you will have super S-level charm on the women around you within five minutes!
Is this ability useful in gambling???
However, her ultimate mission is to capture the female characters. This is the story of a young girl trying to survive in an academy full of female perverts.
(This is actually a love story. The gambling content is just for entertainment. All gambling game content is only for the needs of the plot. In real life, everyone must stay away from gambling. It is good for health.)
