Character: nanachi
Nanachi (Japanese: ナナチ) is a Narehate from the Japanese manga Made in Abyss. 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. Their gender is ambiguous.
Appearance
Nanachi's appearance is very rabbit-like, save for a long sturdy tail, horizontally slanted pupils, carnivorous teeth and human-like hair; which is straight and cream-white 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 though surprisingly agile, as they are very artistically skilled.
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. Nanachi's side bangs seem to be much longer when the helmet is on, going down to their hips, due to hair extensions of the headpiece. They are tied at the end with metal rings.
After Nanachi's stay at Belaf's House, their helmet was redesigned, looking more reminiscent of delving gear now, with the horns curving more upwards and less sharp-looking ends. Its glass-like structures were replaced as one structure. Their helmet also received more feathers and cream-colored animal pelts, which are split into two sections, hanging form the back. The metal rings of the helmet's extensions are now of a much simpler round design and located higher in the extensions, having two feather-like ends hanging from them.
They typically walk upright, but sometimes will run on all fours if they are trying to move quickly.
As a human, Nanachi had yellow eyes and short messy cream-white hair. They wore a light green one piece or possibly just a very large shirt and over it a light brown coat with black sleeves, which was too big for them.
Gender
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 (おいら, which is similar to ore (おれ) 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.
