Nanachi

Nanachi is one of the main characters from the Made in Abyss anime and manga.

Nanachi is a Narehate; a person who survived the 6th layer's curse of the Abyss, and was left deformed as a result, but, unlike most other narehate, still retained a sound mind. Possessing vast knowledge of the Abyss - its ecosystem, vegetation and even the use of the medicines, Nanachi is currently a part of Riko's party, assisting her in reaching the bottom of the Abyss.

Appearance
Nanachi's appearance is very rabbit-like, save for a long sturdy tail and human-like hair; which is straight and white or cream in a short bobbed style, the sides of the bangs going down to the shoulders. In contrast, medium tan fur covers the rest of Nanachi, with light tan covering the insides of their ears and belly. They have a blush-like spot on each cheek; which has two thick whiskers protruding sideways. Other animal traits include a cat-like mouth with little fangs, yellow eyes with horizontal oval shaped pupils (similar to a goat's) and erect bunny ears. Their fingers are rather stubby.

Nanachi's attire consists solely of gray-green, baggy, drop-crotch harem pants, with dark-pink hip-bags on both sides, red pant legs, and a pink flap that is supposed to cover their usually naked torso.

Nanachi also wears a large, oddly-shaped headpiece the same colors as their pants. Attached to the sides of it are two curved horns that stick out horizontally. Hanging from the back there is a large layer of what appears to be shingles, covered by a layer of cream-colored animal pelts, and then another smaller layer of shingles. Strangely, Nanachi's side bangs seem to be much longer when the helmet is on, going down to their hips. They are tied at the end with metal rings. It is likely that these hair extensions are a part of the headpiece.

They typically walk upright, but sometimes will run on all fours if they are trying to move quickly.

Personality
Most of the time Nanachi is cool and reserved, keeping their distance 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. They are also quite bashful when complimented, seen in their reaction to being called "fluffy". They also express discomfort at being petted, especially by Reg.

Observation Skills
Nanachi has demonstrated advanced tracking and stalking skills; when Reg and Riko first entered the Abyss' 4thLayer, although Reg could tell that Nanachi was nearby, he was unable to pinpoint their location. They were capable of tracking Reg and Riko throughout their journey in the 4th layer, continuing to remain hidden, until they voluntarily revealed themself upon seeing Reg scream when he thought that Riko had died.

Curse Detection
On top of top-notch tracking and stalking skills, since becoming a Narehate, Nanachi has been able to see the flow of the Curse of the Abyss — a mysterious force that is behind the ailments human beings suffers upon attempting to ascend from the Abyss. Thus, they are capable of avoiding it.

Extensive Knowledge
Aside from their skills granted to them by their Narehate nature, Nanachi has been shown to be deeply knowledgeable about the flora and fauna within the abyss; they are capable of determining what is edible, as well as if something has any medicinal properties. Their time spent in Idofront has also lead to them knowing how to perform some complex surgeries. Using this knowledge, Nanachi has tended to myriads of maladies that delvers may suffer from, such as being able to splint broken arms, suture open wounds, and even creating an antidote for Orb Piercer venom. Many of the curative methods and medicines they use are unknown even to delvers, who are often thought of to be the most knowledgeable of the Abyss.

Artistic Talent
Nanachi is also shown to be artistically talented, having demonstrated excellent ability in drawing. They have drawn pictures of themself, Mitty, Reg, and Riko; a representation of how the curse works for Reg; and accurate depictions of the things they required Reg to fetch in order to aid them in healing Riko's arm.

Trivia

 * Nanachi is generally presumed to be female, based upon their feminine appearance. However, their gender and sex have never been explicitly stated within the series itself. The only gender referent used by Nanachi is the pronouns that they used to refer to themself with. When talking about themself Nanachi uses the pronoun oira (which is similar to ore but more casual. Evokes a person with a rural background, a "country bumpkin"), which has a masculine connotation to it. The creator of Made in Abyss, Akihito Tsukushi, commented on Nanachi's sex on Twitter, stating: "the sex of Nanachi is unknown. Let's imagine :)." The official English translator of Made in Abyss has also chosen to use gender neutral pronouns. Given that the changes made to survivors of the curse are random, it's possible that Nanachi may not actually have a gender at all.
 * Occasionally there are extra pages at the end of chapters that give more detailed descriptions of the creatures and relics seen; Nanachi often shows up on these pages giving their own insight on the subject. These small bits are called "Nanachi's Trivia."


 * Nanachi has an "irresistible fragrance". In particular, the base of their tail smells really good. They are also really fluffy. This is an interesting parallel between their former human self, who was smelly and repulsive to others.
 * Their age is likely older than appearance suggests.
 * When signing their name, they always draw a picture of their face with the characters for "Nanachi" underneath.
 * Nanachi makes a brief cameo on Pop Team Epic 's episode 2 when (s)he appears on one of Popuko and Pipimi's "Ridiculous Fortunes." It says "Good Luck, Nanachi is cute!".
