Okay, Blaire's backstory:
Blaire Blaze is a girl who grew up in a family of sword maniacs. Tracing back her family tree you'll find numerous famous swordsmen: knights, generals, samurai, soldiers, and more from throughout Europe and Asia. Her parents spent the better part of their lives traveling to every corner of the world with the goal of collecting and learning every style of swordsmanship known to man. Using this knowledge, they developed what they considered to be a perfect style of swordsmanship, one that seemed to bring together the greatest aspects of each technique they had discovered or inherited, and taught the most effective fighting style for any style of sword. However, all their traveling and searching took a large amount of money, not to mention the cost of buying swords and records of the techniques. Now they live in a decrepit house, moldy and falling apart, the only room properly maintained being the dojo they have on the first floor, which they keep in perfect condition for the sake of keeping up appearances, and for their business of teaching swordsmanship.
From the beginning of her life, Blaire was trained with a sword. Her parents had trained their previous child from a young age, and it seemed fine to them, so they decided to start Blaire even earlier. It was only a week after her first time walking 5 steps that she held her first training sword, by the time she entered elementary school she was at a level equivalent to a black belt in several styles of swordsmanship, by the age of eight her skill could put adults who had trained their whole lives to shame, and finally on her tenth birthday her skill surpassed that of her parents.
Although Blaire was a genius with a sword, other aspects of her life suffered for it. She has an aggressive and competitive personality, and has struggled to communicate with others. In first grade she nearly killed a classmate who had been bullying her and her friend, it was considered self defense and she was stopped before anything serious could happen, but she was still expelled from the school. Through the rest of elementary school she didn't make more than three friends, and she was expelled from schools twice when her bag was discovered to have several swords in it. By middle school she had already built too much of a reputation, most people wouldn't approach her, and those that did were typically scared away by her aggressive personality. Those who stuck even beyond that tended to be the worst around, but they would usually get bored and leave when they realized that aside from her violent temperament and aggressive personality she was fairly straight laced.
Having mastered or nearly mastered most aspects of Fencing, Gatka, Kenjutsu, Iaijutsu, Itto-Ryu, Haidong Gumdo, dozens of styles of HEMA, Krabi-Krabong, Kumdo, Siljun-Dopub, Single Stick, Mau Rakau, Jukendo, Krav Maga, many styles of Kung-Fu, numerous other fighting styles that incorporate swordsmanship into their teaching through her parents' martial art, Blaire would likely be the swordsmen alive if it weren't for two things. First, the fact that she was still a young girl and was thus lacking in physical strength. Second, her older brother by five years, Blane, who surpassed her in every skill except sword breaking. Blaire made it her goal to surpass her brother, but on her 12th birthday, when she was finally ready to challenge him, he disappeared and was never heard from again. Thinking that this meant she would never get a chance to beat him, Blaire was enraged. For the next two years she stopped attending school, only working on training herself.
