COLORLESS manga volume 4 features story and art by Kent.

A cosmic disaster erased almost all color from the world, and now the mutated descendants of humanity live in a moody, noir cityscape draped with shades of grey. There is great power hidden in what little color remains, and a secretive cult known as the Order hopes to use that power to awaken their mysterious gods.

Standing against them is Avidia, a gun-toting investigator and scientist who works outside the law. If he's to prevail, he'll need more power--which means surviving an incredibly dangerous new experiment, even as the Order moves ahead with the consummation of all their schemes!
