Nanachi

About
Nanachi is a Narehate—a survivor of ascension from the sixth level of the Abyss. Madness and/or death are not uncommon results of such an attempt but, due to certain circumstances, Nanachi was able to keep their personality and mental faculties intact. Her body, however, was deformed beyond recognition from her original body.

Nanachi looks very young but her vast knowledge of the physics and ecology of the Abyss seems to suggest she's lived there for quite a while. She also appears to be an accomplished medic with significant surgical skills and an extensive knowledge of medicinal plants and animals. Nevertheless, despite her knowledge of the world around her, her cooking is pretty awful.

Appearance
Nanachi's appearance is very rabbit-like, save for a long sturdy tail. Medium tan fur covers their entire body, with light tan being on two spots on her cheeks, the insides of their ears, and on their belly. They have straight white hair in a short bobbed style, with the sides of their bangs being much longer. Their eyes are yellow with the pupils being horizontal ovals, similar to a goat's. Their fingers are rather stubby.

Personality
Most of the time Nanachi is cool and reserved, keeping their distance both emotionally and physically. Their attitude often borders on being sarcastic and even cynical, however behind this mask Nanachi hides a kind and gentle soul capable of deep compassion and selfless devotion.

History
Not much is known about Nanachi's past—they were born in the Far North region of Sereni, lost their family and home at a young age, and were taken to the Abyss by treachery, along with many other children. Bondrewd was working on experimenting with ways to negate the curse of the abyss, and using children as his test subjects. While in the abyss, they met Mitty, another child taken by Bondrewd, who they quickly bonded with. Nanachi and Mitty were best friends, until one day when Bondrewd decided to use the two as test subjects because of their strong friendship. They were each placed in separate connected capsules, lowered to the 6th layer, and then quickly brought back up. The capsules were designed to transfer the curse onto only one subject, while the other received what Bondrewd called the blessing instead. Both survived, but became horribly deformed, Mitty to such an extent that her mind and body were no longer intact.

Nanachi, in their new Narehate form, continued to work for Bondrewd at Idofront until they escaped with Mitty on her back, unable to bear the horrible experimentation Mitty was subjected to any longer. Nanachi lived with Mitty in the fourth layer for some time, trying everything they could to put Mitty out of her misery. Along with the observation on Riko and Reg is in danger, revealling herself is a huge risk as delvers discover a narehate, they will capture and inspect remains on it. She pitied and help them and later joined Reg and Riko in their descent to the bottom.

Abilities
On top of top-notch tracking and stalking skills, since becoming a Narehate, Nanachi has been able to see the flow of the curse throughout the abyss, thus being able to avoid it. She is very knowledgeable about the different plants and animals, and which can be used as medicine or food.
