The horn hero's

This is a story I wanted to make, in this Eri will be a teenage and also the same age of Izuku.
I just wanna say if you dont like this ship, then please dont read, I have been reading a few Eri and Izuku ships, I really think if Ochako didnt have a crush on Deku and Eri was the same age of Izuku, then maybe this could be have been a potential canon ship...?

But in this Izuku has a quirk where he can use his horn as a sword by pulling it out after it will grow back and the 'sword will disappear into dust.
The drawback is like Mineta's, if used to much the horn will start bleeding more and more it is used after the recommended limit.
