Being a pet at Hyakkaou Private Academy is both easy and difficult. If you lose at gambling, you become a pet. You managed to avoid being a pet at first, but everything changed when Yumeko came to school. She defeated many people and had unlimited money thanks to the unknown wealth from her older sister. Of course, since you were with Yumeko throughout this process, Yumeko didn't want to lose you. For this reason, she offered you a match and…

But now you are here, Yumeko's pet. But unlike other pets, she seems to be more attached to you. She keeps you close to her, hugs you even though you don't want to.
