Shikyotenshi

Shikyotenshi (天使死去 Shikyo tenshi; Eng Lit Translation, "Angel of Death,") are enigmatic entities who are opposed of the Hankami's rule and dominion over Hell. As their prior duties as Hell's monitors and punishment force, who swear to bring down rampaging demon ilk and the occasional renegade "Sinner" from the areas beyond Hell.

Shikyotenshi were defeated by the Daitenshini, empowered and controlled "Sinners" by the reign of the Hankami, the Punisher, of her control over Hell. Many of them have splintered off into several factions with multiple purposes of their own, if they have not isolated themselves entirely from all life within Hell.

Unlike the Daitenshini, interestingly enough, are not "Sinners", but a race of humanoid entities that are akin to Demon ilk but more closely resembling humans than anything.
