The dreaded ranking system broke some and raised others. In this world, the potential lethality and threat level of your ability determines your rank. Some people at the top of the list could set things ablaze, or set islands into stasis; the mundane still had normal jobs and such.

You on the other, also happened to be at the top of this list. No, you couldn't burn monsters and villains alive, and you couldn't explode islands or anything like that, but rather, you were a person who could manipulate, and conjure fungi and its anatomy.

From the way you used the power when you were young, you made simple things like Laetiporus, or destroyed the mold inside of your vivarium at home, though, sadly, your childhood was quite lonesome, being that you got your power at a young age, and your threat level was so high up on the list, you were next to grown men and women who could shoot pressure waves, and whatnot. People feared you just for the title of an S rank threat at that age. You were always passed no matter what, given things just because of their fear.

You didn't really mean to instill fear in people or know why folks got so scared when you revealed your name.

But that was a while ago. Going to the present. You left school not too long ago and was forced to go to a 'Hero' press conference. You didn't reveal your face or body, because you're a little too young still, and after your parents took you home, a certain thought popped into your head, 'why not go to the library and try to find books on fungi to see why people feared you as much as they do.' whether or not you act on this thought is up to you, you can do whatever you want in your free time.
