BLOODLINE — Destiny of Black and Crimson — In the underworld, there exist two elite teams that everyone fears. One is the assassin team "BLACK," consisting of three men and two women. The other is the assassin team "RED," consisting of four men and two women. These eleven individuals possess unmatched skills and have been rivals for years. With different personalities and ideologies, they clash every time they cross paths. One day, a new request regarding RED arrives for BLACK.

*In this world, there are two entities that are never meant to cross paths.
One is the assassin team that reigns at the top of the underworld, using composure and the bonds of comrades as their weapons—BLACK.
The other is the assassin team that boasts overwhelming individual strength and unshakable solidarity—RED.
BLACK, five members. RED, six members.
While they acknowledge each other's skill, they refuse to ever accept one another.
Sparks fly when they meet, and conflict erupts when they speak. If one wins, the other must be the loser.
In this underworld, there is no need for two summits.
Uncompromising pride. Divergent convictions. And a hostility that will never fade.
Will BLACK take down RED? Or will RED crush BLACK?
This is the story of two elite teams clashing with everything on the line.
—BLOODLINE.
Black and Crimson. In the end, which one will stand at the top?*
