Enemies in Nioh are varied and challenging. See the Bosses page for the more powerful foes in the game.
The enemies present in the alpha demo of the game were divided into Human and Yokai. Yokai enemies are from another realm, and are marked by a smoky darkness which can take on an area of effect around them. Certain Weapons and Armor provide passive Status Effects that are related to a specific enemy type, such as improved item drops from the specific enemy type.
