Nue

Nue are a complete mystery. In fact, their powers come from this anonymity, as they wield the power of the Unknown, which they use to transform both themselves and other beings or objects into things that Humans fear. There are only very few Nue living at the same time, since they cannot procreate unless they find someone who meets some fairly specific criteria. Their mates are required to both know their true form, and be able to match them in power in all of their forms. They usually target Phoenikoi and Lunar Rabbits for this, although the rare Hell Raven or other powerful Youkai will do sometimes (especially if the Nue is desperate).

They always appear different to different people, meaning that when people try and describe them, they end up with completely different descriptions. They can also have any other type of powers on top of their anonymity, ranging from Power Mimicry, to the ability to kill their opponents by thinking of their death clearly and chanting a certain phrase. Nue all have one weakness though, and that is identity. They thrive off of keeping themselves 'unknown', since their power is practically all gone if they are discovered, and they will go to any lengths to stop their real forms being revealed. It's been theorised, however, that some of the shrewder Nue purposefully allow people to see their true form, but keep them thinking that it's just another facade. This, however, stops them from being able to communicate and socialise with other Youkai and Demons without a huge amount of risk.

Their true forms are either usually extremely monstrous or extremely human, which usually comes as a bit of a surprise. Even if humane, though, their forms usually have some sort of oddity such as a human with cat's ears and a large lizard's tail. Their voice, to those who don't know it for what it really is, becomes a mix of numerous sounds, such as an infant crying, a woman screaming and an old man mumbling to himself, although you can tell what they're saying easily despite this.

Nue pride themselves on being able to hide and scare Humans and even Non-Humans with extreme ease due to their powers, but this also means that they are almost always hunted and killed due to the fear they bring, and they have a general distrust of Humans, since the Humans have a habit of locking them away once they discover their true forms.

Most Nue are, apparently, female. Although Male Nue have been shown to exist and can also coexist just as their female counterparts can, it seems that the females are the more prominent of the species.
