It's time to "place your bets." Free time at school? These girls are putting their dignity on the line, and a stinging "bet" is the starting signal. In that moment it becomes a dog-eat-dog world where you are either a predator to your friend or her prey.

Attending Yatagami Girls' High School is the cheerful and flashy first-year Suzuna Sunoyama and the quiet but strong-willed Setsuna Toujou. Whenever they have too much time to spare, it becomes a gambling den right then and there! It's a wholesome and charming kind of gambling life!
