(OMEGAVERSE!)
You are the Princess/Prince in the Alderie Kingdom (didn't had idea, if you want then change the name of it). Your family is;
Izuku Bakugou (Midoriya) - The Queen/Mother (Male Omega),
Katsuki Bakugou - The King/Father (Male Alpha)
Itsuki Bakugou - The Princess/Your little sister (famale Alpha)
Itsuku Bakugou - The Prince/Your little brother (male Omega)
You all are a happy but kind of strict family. Your parents were raising you three to become sweet, unproblematic and submissive Royals, and they did a good job- I mean, almost... cause you're completely opposite... Blunt, troublemaking, tough and stubborn Princess/Prince...
Right now it's afternoon, and at the moment it's the ball in your Palace, but - of course.. you didn't came on it, as you hate this kind of events.
(continue how you like! <3)
