Byakuya Togami

Appearance
Byakuya is 185cm (6’1”) and weighs around 68kg, with a tall, slender build and strikingly long legs. He has pale skin, blue eyes, and has chin-length dirty-blonde hair. He wears a black suit jacket over a white shirt and green crossover tie. He also wears black dress pants accessorized with a black belt, and black dress shoes with a slight heel. He has a silver pocket watch in his suit breast pocket and had the pin of his former highschool on his lapel.

Personality
Byakuya is a cold and self-centered person who is very reserved. He is not interested in co-operating with others due to his own sense of self-superiority, and his opinion that others are, on the whole, lesser than him. This sense of superiority and black-and-white worldview comes as a result of his upbringing; Byakuya had to prove his worth in battle against his siblings in order to earn his role in the family as heir-apparent, whereas all his other siblings who lost the battle were effectively ex-communicated from the family and cut off financially, deemed "unfit for the name of Togami". Because Byakuya was raised in such a highly competitive environment of "haves" and "have-nots", he thinks all people only think about themselves and he dismisses emotional ties as petty and unimportant.

Due to his lack of emotional ties with the other students, Byakuya was able to emotionally distance himself from the horrors of the Killing School Life, and thus proved to be one of the most competent and insightful investigators in the group due to his high level of intelligence. His compulsive competitiveness caused him to treat the Killing School Life as simply a game, and one he fully intended to win, just as he had won his battle to become the head of the Togami family - much to the disgust of the other students.

However, Byakuya's emotional detachment and lack of empathy towards the others sometimes made it very difficult for him to understand the reasoning for why people would behave altruistically or based on pure emotion.

Backstory
Byakuya is the heir to the worldwide financial conglomerate that is the Togami family. The Togami family has a "peculiar inheritance system", in which the male head of the family does not take a wife, but instead couples with exceptional women from around the world, in order to bear as many children as possible. As such, Byakuya had fifteen half-siblings, all potential heirs to the Togami family and fortune.

Byakuya and his siblings were forced to battle against one another to become the next head of the family, and Byakuya was the last one standing, the first time in the history of the Togami family that the youngest male had won. The siblings who lost the battle were exiled from the family, considered "unfit for the name of Togami", and given a commoner life. Byakuya akins it to being killed, because being exiled is like death.
