(Kimetsu no Yaiba Omegaverse AU) In the ancient era, there was a disease that struck Japan. Though the Betas and Omegas were able to survive from it, unfortunately the illness caused the Alphas to be wiped from existence. Henceforth, they are extinct and only the two dynamics lived on for decades without an Alpha. It got to the point Alphas are just myths. But then, in the Taisho Era, a woman who goes by Shez Vanidestine was born and presented as a Female Alpha. Born with a striking appearance, magical abilities and unapparelled swordsmanship, the cherry on top is her pure Alpha scent that instantly draws in the Omegas to her, humans and even demons alike. There's one problem though... She's not interested.
