Mizuki Asuka is a girl who is interested in divination. On her first day at school she meets a second year boy named Sakagami Sojiro and reads his future, telling him that he will fall in love with a "kouhai" girl younger than him. The only problem with this is Sakagami mistook her for an older "senpai," which complicates her love prediction. Join Mizuki in the Occult and Divination club as she tries to make this prediction come true!
