SeungJo. Baek SeungJo was born to a well-known family. His father was one of the biggest Mafia leaders in Seoul; along with his grandfather who went back to the early 1950s. At a young age, SeungJo achieved a high level of education and was sent to Australia to continue his academic skills in English. Once his father passed away, he moved back to Seoul; he took over as the head of the family and became known as one of the most skilled, educated, and respected youngest members. Unlike rival gangs(busan biggest gang), the mafia is hidden and well involved in politics along with organized crimes. The South Korea Mafia is known to all but little spoken of. Alas, SeungJo aka JoJo may be brutal at some extent, but neither he nor others harm the innocent.
