Sapphire

I don't know if this is a backstory (or a description / backstory) or not but anyways here it goes:

''Sapphire was born and brought up in a really rough part of Osaka, her parents were always getting nicked (arrested) for dealing and selling drugs, Sapphire was also always getting nicked for the same reason. She was always getting bullied throughout primary school, ever since the first day of high school, things slowly started to change. She would still go to school as normal but she would refuse to go to any of her classes, she would hangout at the delinquents' area. If somebody tells her to do something (either the headmaster, teacher or the guidance counsellor) she would simply refuse to do it. If something doesn't go right for her first time around she blames the person who's standing close to her. When one of the male delinquents (hint Osoro's righthand man) approaches her, she will quickly turn shy and will end up stuttering when she talks to him.''

Just a little bit about her.
