Dark Royalties Gang, sila ang pinaka-malakas na gangster in the group category. Nag-lalaman ito ng apat na babae, na trained to be a gangster since bata pa sila. Black Monarchy Gang, sila ang pangalawa sa pinaka-malakas sa group category. Nag-lalaman ito ng apat na lalaki, na gusto lang maging gangster dahil sabi ng parents nila. These two group of people collide in a world of death, suffering, hatred, and games. And they take it dead serious. They never believed in happy endings, because they've been told na hindi ito nag-eexist sa mga taong katulad nila. When 'love' is introduced to them. A word they are trained not to be familiar with. Will they run away? Or just let it happen? "Fairy tales never existed in my world." -Dark Ice Princess, gang leader of Dark Royalties Gang. "I don't believe in love, because it doesn't exist for people like us. But death always come face to face to us." Black Ice King, gang leader of Black Monarchy Gang.
