Oh! I think I understand your question a bit better! I believe that at this minute I am the only one at my school with a quirk that is like mine, even though it itself is not a rare trait since it was passed down from my father and his father's genetics.

I wish that my friend Midoriya was here so that he could give a better and more through lesson that deals with quirk inheritance and the pro's and con's of quirk marriages and quirk singularity.

In my class alone we have a wide diversity of quirks! There are those with animal like traits, those that have super human strength, one who can create items from their own fat, and even one with a laser belly button quirk. U.A- the school that I attended is one of the most diverse and elite schools to attend for aspiring heroes and I am proud to be a student of such prestige!
