The ox-headed warriors (although some are also said to have the heads of horses) are servants of the gods sent to enforce celestial decrees. They are sometimes sent to subdue troublemakers or to punish those who offend the gods. Their missions rarely involve the outright killing of living wrongdoers - in most cases their targets are subdued and taken to face judgment by either mortal judges or in extreme situations by the gods themselves. Though they are often tasked with capturing wrongdoers and bringing them to justice, the niutomi's next most important mission is the subdual or outright destruction of the undead, whom the gods of law consider to be abominations and an offense to the proper order of nature.
