Magicless Adventure

Classic Fantasy AU where everyone received their magical abilities and Mana levels at age 4. Well, except Izuku. That didn't stop Izuku from wanting to be a heroic adventurer like the Hero All Might! He trained at home. His dreams were nearly crushed when he presented as an omega at 12 years old. Omegas weren't allowed in the adventurer's guild unless they were mated to an Alpha. Izuku wouldn't let that stop him. He found a way to conceal his scent and pretended to be a Beta. He will follow his dreams no matter what.
When a Prime Alpha with a nasty temper named Bakugou Katsuki challenges him to be the first to be an S-Ranked adventurer, well, he isn't just going to stand aside.
Bakugou Katsuki had always been the best at everything, so when some magicless Beta starts climbing the ranks faster than him, he's not going to just stand aside. Challenging the Beta may just lead to some feelings he'd never felt before. What's a prime alpha to do when this dorky, sassy, beautiful beta proved to be the challenge he was hoping for? Court him, of course. But courting a beta isn't like courting an Omega; he can't just flaunt his scent around. It's time to learn communication skills to get this Beta's attention.
There will be smut in this, but no Mpreg.
