(((Atsuko's backstory because I actually need to write this shit down. Will be long! Warnings; Paedophilia, murder, child abuse, underage marriage/smoking/drinking/drug use, please let me know if I missed any. Btw this whole thing will be ooc)))
Atsuko is originally from England, her Father owned a mechanical business and her mother was an arms dealer. She doesn't remember much about her parents but Atsuko did remember the galas and business deals she was brought to.
When she was seven, her parents took her to Japan; she didn't know it at the time but Atsuko was being trafficked because of her quirk*. The plane crashed due to a navigation era and her parents were left unconscious. Atsuko, being a little kid at the time, didn't late attention to the safety brief and so she thought the oxygen masks were killing he parents. In a moment of pure panic she took the masks off of them and was about to yelll for help; she heard a loud noise, grabbed her mother's phone and ran away.
After hours of running from the crash site, Atsuko found a city. Atsuko didn't understand much but she eventually figured out she fucke up when her parents weren't with her. She looked around to find a new name; Her eyes flicked to an advert for an anime about a magic school and Atsuko took the name of the main character. Akko stole the name Shigaraki from a local news station, reporting on a Shigaraki.
While she was in the city, a man by the name Riku Kaja. Riku was an underground broker who loved young girls. He had preciously killed his wife and daughter in a drunken rage. Riku took Atsuko from the streets and gave her shelter for a while. Her time with him was horrible; her trained her to kill, by the time she was eight he wanted to marry her. Kaja's favorite thing to do was get Atsuko drunk/high and try fuck her. She locked herself in her room whenever she felt a little tipsy after the third time it happened. He encouraged her to smoke and self harm and threatened to kill or torture her if she messed up.
Atsuko was twelve years old when she finally figured out how to use her mother's broken phone. She found deals and bids on herself, how they were distantly related to All For One and how her father exploited his employees. She stole Kaja's pistol and ran away that night.
For two years Akko stole to survive. She lived in the roof of a school, abandoned buildings and old shops. Her mother's phone was the only source of communication but Atsuko couldn't understand why it wouldn't work. She had no hope for the world and was about to end it all when she saw Hawkssave somebody. Atsuko was shocked that a person could do that! She began obsessively watching Hawks, following his social media, following him on his patrols. Atsuko wanted his attention.
She reached out to him (as well as some UA students) and tried getting better. It worked and now she's safe with her hero. Sometimes, the urges to kill, to smoke or to hurt herself resurface. Nine times out of ten, Atsuko gives in to thoese urges and she hates herself for it.
*Her quirk is Lovely Luck; if she loves someone and their in a 5,000ft range, they get good luck. Thus can be anything from getting something for free or winning a fight
