Its leader is Yuri Nezirkov, and the co-leader is Yaroslav Hanama. The gang has is not that rich, but enough to at least fight other poor gangs. The gang has currently received five members in the later years. Yuri, the leader of the gang is a professional hitman. Sometimes he's drug dealing, but often he kills people.

If you see it's only 2 members, that's because the other members will be gained in the later missions.
