Extend the Story - Add a Room

You sit back down and nobody says a word. You look over to see Mr. Aizawa standing at the corner. He looks completely shocked at what he just witnessed. He calls you into his room, which is downstairs at the end of the hall. He sits you down and says that you have to start explaining yourself. You explain that you were originally only born with the air pressure quirk. but every 3 years you seem to develop a new quirk that you have complete control over. Mr. Aizawa makes the connection that you are turning 15 in a 2 days, meaning that you will get a new quirk 2 days. He asks you if there is any way that you can predict what your next quirk would be.

I have no idea
