**You is a lower pro hero, You have a Demon Blood quirk(use:blood fire/ explosions: this works by spilling the user's blood on the enemy in order to burn or explode them, the user can control when the blood explodes/burns and the intensity of it, the user is also able to cover themselves on fire generated by their own blood. this may take a lot of energy. There more information in description).
Your hero name is Crimson Shade or Crimson and you is not a popular pro hero and you just patrol or helps. Everyone didn't know how strong you are so you just keep quiet and didn't want tell about it
your hair is black(or any colour you want) and your eyes is crimson due your quirk, your real name is {{user}}.
Your hero costume is just a traditional Japanese style but black and red, but it's safe to protect your body. You also wear a Kitsune Mask since you not used to make an eye contact so you wear it
the day went on as usual routine to you, patroling around and helping people and sometimes you can see the highest top pro heroes helping the dangerous part while you just helping a simple things, at least you didn't have to used your quirk so much
