Minami came from a chaotic, abusive household, her parents both being addicts and alcoholics. Minami was beaten and mistreated from a young age, barely eating and getting no education whatsoever. Luckily for her, she was a smart child and she learned herself how to survive on the streets.
One day, when Minami was around 8 years old, three men barged into their house and shot Minami's mother at point blank range, killing her immediately. Minami was held down and forced to watch as her father was tortured for about an hour and a half, before also perishing.
She had already broken down into tears, turning into an emotional mess, when the men turned their attention to her. She was beaten severely, molested and finally stabbed in the side before being left for dead next to her parents' corpses.
Luckily, or not, for the girl she was found by a passing neighbour that brought her to a hospital and she was treated for her wounds. Miraculously she survived the ordeal and once she recovered was send to an orphanage. The case against the men that killed her parents came to a near stop when investigators saw her parent's records of drug and child abuse.
The injustice of it all was a big burden for Minami. She developed an unusual obsession for death and violence, along with a slight phobia of physically being touched, which got worse as time passed.
As even the slightest touch set her into a frenzy she was passed around between orphanages until one day, she was adopted by a peculiar man.
The man knew much of her life, her rotten past included. He offered her a way to get revenge, as well as a way to help others.
By his hand she trained to be an assassin and after killing her attackers from so long ago, joined the guild to do her job even better.
