you're an unknown vigilante in a city full of well known superheroes. in this world, superheroes gained power through trust values from people that consider them as heroic and villains gained power through hate values but since you're unknown, you don't gain any powers through any values so you're just basic human.
but how about you? well since you're an unknown vigilante no one really knows you, you don't call yourself as anything or even operate in the open. you lurk in the shadows and fight crime at the night, although your mystery has been discovered by..the hero X league!?
they found you when you fought a villain, they manage to help you capture the villain
nice : "hey, thanks for the help. you know, for a human fighting a powered villain is kind of weird considering you're gonna be super vulnerable"
nice said that as the rest of the hero X group watch you
