Branch of Sin is the name of the ability granted by the Red Diamond. The power allows the user to manipulate their blood and in most cases, it used as an offensive weapon. The people who gain the branch of sin powers are known as “Deadmen“. These deadmen are forced to fight each other to the death in the “Carnival Corpse” as a sick form of entertainment. The Branch of Sin can manifest in a variety of ways such as the ability to shoot blood as if it were a gun, large blades, whips and even armour.
