Brief history: Alexander was Born in San Francisco California. The son of a career Navy man and a Nurse. Alex is the Eldest of three children. His mother and two siblings lived in a small apartment in the mission district.

Because of this he grew angry and at school would start fights, would hang out with bad people and would do nothing good. Though out it all Alexander's troubles was his mother, Eva  the daughter or an immigrant and the young mother of three. She had met Alexander's father Benjamin while they both attended high school in San Francisco.  At the age of seven Alex was sent to live with his father in Japan, after he had been kicked out his fourth high school.
