Narehate

Narehate (成れ果て) or Hollow are generally known as beings who have survived the 6th Layer's Curse and whose bodies have become deformed as a result, although there are other means of becoming one. They can take many different forms depending on the circumstances of their transformation. Their exact properties as a species are unknown. The word "narehate" comes from the term "narenohate" (成れの果て) which means "the shadow of one's former self".

Many of Bondrewd's experiments at Ido Front ended with his test subjects becoming Narehate, which were abandoned in the Miniature Garden Of Dawn on the 6th layer. Most end up as amorphous blobs of flesh with little to no brain activity. So far, Mitty is the only known Narehate that is near-indestructible, can survive without food or water, and can neutralize any toxins she comes into contact with. Any physical wounds received simply heal, though the tissue becomes slightly more mangled with each regeneration. However, certain Artifacts, such as Sparagmos and the Incinerator are capable of inflicting permanent damage to her. Inside Ido Front, once experimented on by Bondrewd, a Narehate's life status can be seen and represented by their life signatures, which are encased in tubes. Their status is either represented by a reddish light, meaning they are alive or no light, meaning they are dead. In very special circumstances, due to a practice that places one person's burden of the Curse onto another, sometimes the effects of the Curse can be nullified, and what is received instead is what Bondrewd refers to as the "blessing". The result of this ends with the subject still being deformed, but their mind and overall anatomy remains intact. Rather than becoming unrecognizable, people who receive the blessing gain animalistic qualities such as fur and claws. The only two known beings who have become Narehate due to this method are Nanachi, and Bondrewd himself.

Faputa is another Narehate similar to Nanachi and Bondrewd, in that she is humanoid and intelligent, though noticeably more animalistic than either of them, both physically and mentally. She originates from Irumyuui, who gave birth to her using all three Cradles of Desire that Ganja had collected.

Iruburu
"Majikaja"

- Every Narehate's body more or less took on the form of their desire.

Narehate at The Village of Iruburu are very different than the Narehate at Ido Front. They take many different shapes and forms, and seem to be made of many different materials. Majikaja stated that when someone chooses to become a Narehate, they become bound to the village and cannot leave, but in return receive the form of their desire and the village's protection. While many of the Narehate at Iruburu seem to be somewhat amorphous, most of them retain at least some sense of their humanity and are able to communicate with one another using Iruburu's language or gesticulation. Some, like Majikaja, are even able to speak the language of the Delvers.

Trivia

 * According to Nanachi, guessing it is better to simply tell people they died than the alternative, when Delvers spot a Narehate they put them to death and collect their belongings.
