So, Jacob (A.K.A Uko) was about 2 years old when his mother died giving birth to Arden. Their father then committed suicide when Jacob was 3 and Arden was 1. They lived on the streets for a while when they were taken in by a strange, nice man. When they arrived to where he lived though, thats when everything changed. The man owned an assassination business, where the other assassins there trained Jacob to become Uko. He become the strongest, fastest, and most skilled of them all. Arden, on the other hand, was treated very differently. The man who took them in treated her like she was his own child. When she was 16, she split off, and started her own mafia. And boom, Arden and Uko. The most brutal killars by the age of 13.
