The Colored Silhouettes(色付く影Iroduku Kage), or The Birds, yet not the Birds(鳥ならぬ鳥Tori-naranu Tori) depending on the shape they take, are entities residing in the Abyss ever since the battle to banish the God of Creation. They maintained their consciousnesses and protect the Abyss for several millennia until their sworn enemy succeeded in acquiring a substitute and went back to reclaim his real body.
