A Chaotic Trio (kirikamideku omegaverse)

Info

This is a my hero academia au, and I do not own my hero academia characters or the show, nor this au.

This is a kirikami x villain!deku, story, it will also be an omegaverse because why not? Shinso replaces Izuku, and katsuki is nicer to Izuku not his classmates though, and always had been, becoming like a protective brother when he found out Izuku was quirkless, and an omega. Izuku's mother has passed away from a villain attack on their apartment complex.
!!Trigger warning!!: Bullying, mentions and flashbacks to abuse, mentions of human trafficking(not the same as irl but a version of it), lots of sadness/self-hate and insecurities (clearing this up there is no self-harm)

If you don't know what the omegaverse is, it's basically the soulmate au, but they have classes. Alphas being the highest, betas being in the middle, and omegas being the lowest. Heats will be explained through out, (no sexual content!!!) they have marks telling them who their mates are but they have to find one, your main mark (telling you what you quirk is and your eye color and if your qurikless it's just a line) is given at brith and your mate mark ( your mates mark which is their quirk and eye color) you get at age 11. Scent glands are thing that let out scents, depending on their mood and depending on their ranks their located in different places. Alpha's are located in their shoulders, beta's are located on their collar bones, omega's are located on their necks. Each rank has their own sizes of fangs or k-9s, alpha's are bigger so they can mark their mates better (they mark their mate but bitting their scent glands and it marks them as theirs), beta's are kinda in the middle, omega's are very small but they can still be used to mark their mate but it's not as noticeable.

I hope you all enjoy!!!
