Nakuna

The girl that had cursed Nadeko with a Jagirinawa after her crush got rejected. Nakuna is a cynical girl, being a bully towards Nadeko.
~!Eventually, after Nakuna's curse was lifted from Nadeko, the remaining Jagirinawa had fled and returned to Sunshi as well as Nakuna, likely due to it being a fake oddity sold by Kaiki. When Nadeko meets her again, she is covered in holes that allow her body to be seen-through. This is likely from the Jagirinawa eating away at her, rather than killing her, due to it being a fake oddity. She isn't harmed despite the holes, moving around fine.!~ ~!Later on, Nadeko cures her, though she must be hospitalised and is still afflicted with the curse. Nakuna and Nadeko forgive each other for the whole thing.!~
