Narehate are beings that had their bodies deformed by the Abyss' Curse due to an ascension in the deep layers of the Abyss. They appear in many forms in Narehate Village in the sixth layer. It is said that their appearances are determined by the desires they carried at the moment of the transformation. The Lord of Dawn describes the Narehate as "blessed" by the Abyss.
"Every Narehate's body more or less took on the form of their desire" -Majikajya
Nanachi is the first Narehate that Riko and Reg encounter.
