Nanachi

About
Nanachi is a Narehate—a survivor of ascension from the sixth level of the Abyss. Due to certain circumstances, Nanachi was able to keep ze personality and mental faculties intact. His/her body, however, was deformed beyond recognition from his/her original body.

Nanachi looks very young but his/her vast knowledge of the physics and ecology of the Abyss seems to suggest s/he's lived there for quite a while. S/he also appears to be an amateur medic with significant surgical skills and an extensive knowledge of medicinal plants and animals. Despite this knowledge of the world of the Abyss, his/her cooking is pretty awful.

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

Personality
Most of the time Nanachi is cool and reserved, keeping his/her distance emotionally and physically. His/her 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—s/he was born in the Far North region of Sereni, lost his/her family and home at a young age, and was 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, s/he met Mitty, another child taken by Bondrewd, who s/he quickly bonded with. Nanachi and Mitty were best friends, until Mitty was chosen to be experimented on. Nanachi, worried for Mitty, followed and Bondrewd decided to use the two as test subjects because of their strong friendship. Each were 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 and became Narehate but Nanachi retained her humanity because of Mitty's love for Nanachi ("Please... let my soul return to Nanachi").

Nanachi, in her/his new Narehate form, continued to work for Bondrewd at Idofront until s/he escaped with Mitty on her/his back, unable to bear the horrible experimentation Mitty was subjected to any longer. Nanachi lived with Mitty in the fourth layer for some time. S/he experimented on dying Delvers to figure out a way to kill Mitty. The bodies of these Delvers are buried in a graveyard behind her hut. Nanachi is careful to reveal her/his-self because Delvers murders Narehate they come across.

But, Nanachi does reveal her/his-self to Riko and Reg after s/he sees Reg crying over Riko's body. Because their relationship closely resemebled her/his relationship with Mitty, s/he aids them and eventually follows them to bottom of the Abyss after Mitty is released.

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.

Trivia

 * Nanachi is generally presumed to be female, but her gender and sex are never explicitly stated, and when talking about themself Nanachi uses the gender-neutral pronoun "oira." The author confirmed this by tweeting out "The sex of Nanachi is unknown. Let's imagine :)."
 * Nanachi has an "irresistible fragrance". In particular, the base of her tail smells really good.
