Scar Chain

Scar Chain (自由の鎖 (スカーチェイン), Sukā Chein; Japanese for "Chains of Freedom", sometimes called Skull Chain) is a group of Deadmen that opposes the prison and plan to leak the truth to the rest of the world. They believe in each individual's own personal definition of freedom. They are lead by the Deadman Owl (real name Nagi Kengamine). His second-in-command is Karako Koshio, known as Game Fowl, who secretly loves Owl and fights for his sake.

They set op an operation to escape DW, but in the end only few members of Scar Chain escape.
