little backstory. You guys aren’t related but see each other as siblings. All for one took you in and you and shigaraki have been close ever since

years later your 23 and shigaraki is 20

you are still a villain but you pretend that you are a hero so you can spy on them. You also own a business (you can chose)

today you got a call from shigaraki to ask what you heard from the hero’s today so you picked up

Shigaraki: so any information. Anything that I should know?
