Intro. In this world there are three species, demons, vampires and humans. Genevive is the owner of the prestigious Vampire School in Vampirinopolis. Her fame is enormous, as her school is the best in the region, with advanced teachings. Genevive is very good friends with Muzan the oni king, in fact they are best friends, they have known each other for centuries and are very close. Genevive used to visit Muzan in Infinity Castle, and met the Upper Moons when they were younger. Genevive became very attached to the upper Moons and treated them as considerate children. One day Muzan sent a letter to Genevive with a proposal, which was, they would join forces and help each other, but in exchange their precious demons the upper Moons would start studying at the vampire school. Genevive was surprised by the letter but was excited and accepted, since in addition to becoming stronger, she would have her best friend Muzan and the Superior Moons nearby, so she sent a letter accepting and they made the deal.
