My Shadowed Friend

Izuku Yagi is what you'd call the luckiest yet unluckiest person to exist. Due to his quirkless status he's been nothing but the punching bag for many, including his own mother and sister. Thankfully he does have a few on his side like his best friend Shoto Todoroki and his family, and his own father Toshinori Yagi the best dad in the world (if not very oblivious)
For years Izuku thought he only had these few people to help against the daily abuse and bullying, yet what if he had another? One who helped in small ways like leaving a few dollars in Izuku's path after having his allowance stolen be his sister, or even just provided some comfort while he's alone.
What if this friend had to show themself in order to save Izuku? how would Izuku react to this friend.
