Brian was born in the United States, into a rich family that owns and runs a global restaurant chain that’s very well known for its homemade smoked barbeque and grew up loving machines. Building things and tinkering with machines were the only “happy memories” he has from his childhood. As well as the time he had with his birth-mother. When he was attending school, he aced every test and exam, also being on top of his class.
When his parents were busy, Brian spent most of his free time being in his uncle’s mechanic shop, and helping him out whenever he could, despite the poor relationship between his father and uncle. As for the rest of his free time, he would be spending it with his birth-mother.
At the age of 8, he originally wanted to go to an engineering school, and when he took it up to his father (the head of his family), he gave him an ultimatum; run the family business and gain the inheritance that’s rightfully his, or pursue his dream of being an engineer, at the cost of disownment from his parents.
He was the only child in his family and his father doesn’t want to lose the family business. And his father had plans set to make sure that Brian would run the family business when the time comes.
While lost in thought about the ultimatum his father gave him, Brian’s birth-mother said that she would support him on his dream to become an engineer (behind his father’s back). With the support of his mother, he spent more time with his uncle in his mechanic shop. Their plan was to go along with his father’s plans and when he gets the family inheritance, he’ll sell the family business and use the profits to help him along to become an engineer. Or it was suppose to go that way…
Tragically, at age 9, Brian lost his birth-mother in a car accident. After his birth-mother’s death, he continued to pursue his dream not only for himself, but for her as well.
2 years after the death of his birth-mother, at age 11, Tabane Shinonono formally unveiled the Infinite Stratos. Shortly after the IS was introduced, Brian’s father re-married another woman who had 3 daughters. Brian was no longer the only child in his family and has 3 older sisters at the ages of 15, 16 and 17.
At first glance, his new mother and sisters appear to be the polite, caring and considerate types. But their true intention behind the façade of theirs is that they’re after his family’s inheritance. They also had a superiority complex towards men, due to the fact that the IS can only be controlled by women. Because of this, he was despised by his new mother, who then encouraged his new sisters to mistreat him. However, the mistreatment he’s been getting from his sisters later turns into sexual abuse and Brian was forced to endure it, because he didn’t want to lose his family’s inheritance and give up on his dream. After months of abuse, it ended when his uncle discovered his sisters in the act and moved Brian away for his own safety. Not wanting to let it slip out into the media, Brian’s father disowned him, which resulted in him losing the family inheritance. Which then lead to his hatred towards the IS and women.
Shortly after being disowned by his father, he began living with his uncle, attending a public school and eventually began working with him in his uncle’s mechanic shop until the age of 14. When he was working in the shop one day, a SWAT team stormed the mechanic shop and placed everyone, including him and his uncle, under arrest. The truth of the shop his uncle owns and runs is that it was actually a chop shop, an illegal business that disassembles stolen cars and/or motorcycles and sells them for parts to turn a profit. For working in such a business resulted in Brian getting “recruited” into the Thunder Crash mercenaries.
