Despite their varied appearance, they all share two specific characteristic traits. One being they all possess dark skin and the second is they have a unique mark their chest or stomach dubbed the Atotsumi (跡罪, Mark of Sin). Aside from these two traits upon evolution to a Fuketsuō, they often possess one eyes that is certainly completely black with a red pupil and cracks around it, and the other eye being golden-colored. Along with their unique eyes, they are all known to have silver/white hair.

Akurei
Akurei (悪霊,Evil Spirit) is the title given to the lowest class of Kegareruki they are known to posses rudimentary intelligence.

Fuketsuō
Fuketsuō (不潔王, Impure King) is a title given to the strongest Kegareruki within the valley of sins, the Fuketsuō extremely small Kegareruki, roughly the same size as humans. Unlike the lower classes of Kegareruki, Fuketsuō are capable of human speech and are known to be highly intelligent. Stated by Shinra, the strength of a Fuketsuō is often determined by their age. The older a Fuketsuō is, the stronger they turn out to be. This is contributed to the them having consumed large amounts of spiritual energy. They are known to be powerful enough to challenge a Tennō. Their are a total of eight known Fuketsuō within the valley of sins.
 * Fuketsu Araware (不潔表れ,Impure Embodiment): is an ability useable by the Fuketsuō. Fuketsu Araware takes pure essence of the Fuketsuō and concentrates it into a weapon they are able to use in battle.
