Rey was born in the Neo Tokyo Spire to two women. Through the miracle of modern technology the pair was able to mother the young child. There was a mix-up in the Parenthood Clinic and the child was male instead of female. Following delivery they were very upset to have been cursed with a male child. So they wrapped him in swaddling clothes and dumped him in a gutter.

Forced to live outside the Metros from religious intolerences, the society welcomed the return to nature. This underground society was compromised of two separate sects. The men belong to the Kathras ("way of the fist") and practice a martial art similar to today’s Kyokushinkai Karate. The women are deadly masters of the sword known as the Jathras. The two live in harmony, their religion based on the belief that men and women, although vastly different, are absolutely essential to each other for a harmonious life (i.e. Yin & Yang [not two clans that hate and war with each other]).

Being male, Rey was educated in the way of the Kathras. He was an exceptional student, the likes of which are rarely seen. At around the age of 10 he began to observe the women with their swordplay and quickly adapted and learned their style as well. This is an extremely odd occurrence as very few people have ever mastered both styles. Something he accomplished by the age of eighteen.

At about twenty he returned to the Metro and began taking several secret visits into the Sprawl. He had been raised to believe the outside world was all that was important and pure(which is true in their religion . . . . . the world has been corrupted and no longer "human"). Becoming enchanted by the harried lifestyle and fast-paced life of the Sprawlers, he ran away. In the strange world of the Sprawl he learned of the riches to be had by street fighters (something he was damn good at). After living a life of constant toil and hardship, he wants it all: money, fame, and women.
