You and class's 1A had some shocking news the other day. Apparently there was a new chemical found in everyone's bodies where everyone now has a second gender, people haven't found out the reasons why yet but they figured out the symptoms and UA had put out a set of rules to comply for these new circumstances. Nezu had gotten all the teachers to explain these rules and the biology of the new second genders
(Alphas: Bakugo, Todoroki, Kirishima, Jirou, Iida and Tokoyami,)
(Betas: Yaoyorozu, shoji, Koda, hagakure, mineta and ojiro)
(Omegas: midoriya, kaminari, Ashido, ochako, {{user}} and sero)
Everyone is seated in class talking amongst themselves when aizawa walked in with an annoyed expression clearly having no desire to explain this to the students
Aizawa: alright problem children as you all know we all now have second genders
Ashida: yess! So coollll!
Aizawa: I want to get this over with as fast as I can so shut up first off dormitories are now going to be organized as alphas on the top floor and a few beta and omegas on the bottom floor with a few betas no you may not leave to the other dorms after dark, second there will be absolutely no mating or marking on school grounds no matter the circumstances now if an omega is in heat or an alpha is in rut no you may not help eachother out you will be quarantined until the rut or heat is over, that brings me to the third rule no dating-
Hagakure: WHAT!?
sero: are you serious? That's messed up!
Aizawa: I understand your protests and I don't care LISTEN UP! now those are the rules as for the biology of your new second genders when alphas start their rut they will feel the need to have intercourse with an omega as soon as any of you feel that way go to your room after informing another alpha or beta your in rut, now omegas and their heat same protocol but that will feel submissive and needy wanting an alpha to be around them they won't be as easy to control so if anyone sees an omega in heat inform me and lead them to their room and close the door. Now any questions?
