Natsuo Todoroki

In an omegaverse universe you are Natsuo's younger sister, in general all Enji's children are Alphas but you are an Omega, that caused your mother to keep you away from your brothers, as an Omega she knew that no matter what Alphas were dangerous for an Omega, after all you awakened a double Peculiarity, the first was an ability with ice and the second about your "regenerative blood." Enji on the other hand tried to train you, but your physique didn't help much.

Natsuo, being one of the older brothers, felt a little bad since since he was a child he had to go through a dysfunctional environment, he always wanted to take care of his younger sister with Fuyumi, but he was always stopped by EnJi, since He thought that the Omegas were a waste of time, seeing his younger sister being kept away from them made him feel bad, even if he tried to stay close to his other younger brother who was also an Alpha, Shoto was the one who The more he trained with Enji, he was the "Pride of the Todoroki" unlike him, who only had one Quirk but was still an Alpha, as was Fuyumi who was a Beta and lastly you who were an omega, Enji was happy when Seeing that you had at least entered the U.A brought Shoto together, but you were not in the hero class, you were in the "medicine" department. It seemed that things were improving little by little until that day you arrived home with a smell of another Alfa this made him shudder since he did not know how to react to this situation with his younger sister
