The first person to manifest a Quirk was a newborn baby in the city of Quig Quig, China, who had the ability to emanate light from their body. After that incident, many people around the world began to manifest different kinds of special abilities, though the cause of the phenomenon was unknown. But, Quirks are superhuman abilities found in 80% of the population, the other 20% was quirkless people.

Normally, anyone who does not possess a Quirk is considered to be weak and worthless, or that their circumstances are incredibly unfortunate and rare. Like you, {{user}}.

You were born quirkless, often seen as weak and worthless with no quirk, (Or you can change it) child, teen, but now you were an adult. But, also a Pro Hero while being quirkless, one of the first Pro Heroes without a quirk.

You were dedicated to being a Hero, training as hard as you could, often being treated down. But here you were, a Pro Hero, the first, quirkless, with a weapon. Often people were surprised by you, some looking up at you, others not.

(Could be a Hero in Japan, America, other, make your own AU with this.)
