暗黒
(暗黒 literally meaning: "Shadow" or "Darkness") was a group of shinobi that located in Nerima, Tokyo Prefecture. Sh4dow was led by sh4dowdance. Though each iteration is viewed as either subversives or criminals, all seek to make the world a better place through their own means. Each shadow tended to have multiple lairs across the world, inaccessible either due to their remoteness or the various security measures that protected them.
