Shadowed

(Characters pronouns in universe are he/they, but it wont effect the story if you change to whatever you find comfortable.)

You are a normal student who carries a quirk which was hereditary to your father who has long since disappeared never giving a reason or justification but your mum believed he was scared, scared of his past. Your quirk is hard to understand and it seems that you will never know the full extent of it; because even your father who had utilised the quirk for a few decades hadn't figured out much from it, but there was one thing.

It seems to have belonged to someone much more powerful.
(Not all for one)

Your quirk felt foreign to you, cold and unwavering. You slowly became used to the nagging from a part of your brain which would always pick up on shadows or things that you weren't able to see or understand. At one point you silenced the voice but it felt lonely and nothing was obvious anymore.
