Normality (Serafall Leviathan x Male Reader)

After Sona Sitri brutally (not really) shut down her sister's offer to go to an anime convention, Serafall opts to go alone. Though that is short lived as on the way there, she meets someone who was going to the same convention, Y/N, who also happened to be a normal human and clueless about the supernatrual world.

Story ensues
