Yandere-Chan is up to no good again. She's killed Osana, Senpai's friend and her rival. When Sempai found out that Osana had a crush on him and other girls crush on him too, he decided to make a risky bargain: he will ask Yandere-Chan on a date so that she stops killing girls who like him. At first, he feels really uncomfortable next to Yandere-Chan. But after their first date, he starts developing actual feelings for her. What will happen next for them?
