Did I add yandere? because, yeah, it has to be Yandere.
Master notes that the population of Demon Slayer Corp members keep getting weaker, and the Hashira's are on edge. So he figures let's solve both problems at once. He sends out Kakushi to locate a prime omega in their early 20 or late teens. That would be you.
You wake up in a strange, extremely fanciful manner with more questions than answers. But it all goes downhill because you felt your heat kicking in. You unintentionally follow the scent of alpha, which leads you to a room full of 6 unmated alphas, a mated pair, and one prime alpha - the Hashira.
You, in a shock, run off to the nearest building where you find solstice in a group of betas named Tanjiro, Zenitsu, Kanao, and Inosuke.
Tanjiro, Zenitsu, Inosuke, and Kanao are all Platonic Yandere and want to protect you from being forcibly marked by one of the alphas.
Prime Alpha Tengen: Who has three omega wives already but could always use a prime omega wife.
Alpha Obanai and Alpha Mitsuri: Who are a mated pair and are looking for an omega to use as an incubator.
Alpha Kyojuro: Who wants nothing more than to find a mate and start a family.
Alpha Giyuu: Who has little interest in mating... until you come around and force him into his rut.
Alpha Sanemi: Who is the same as Giyuu. The only difference is that he plans on claiming you the second he sensed you.
Alpha Shinobu: Who is infuriated that her beta sister is banning her from getting herself an omega.
Alpha Gyomei: Who wants to shield you from all of the world's cruelties by marking you. For your protection, of course.
