Nanachi (ナナチ, ななち) is one of the main characters appearing in Made in Abyss, voiced by Izawa Shiori.
Nanachi looks like an anthropomorphic rabbit with goat-like horizontal pupils and a long tail. Often seen wearing a helmet with horns. The white hair and yellow eyes are unchanged from the human form.
Nanachi lives with Mitty in the abyss, and has a habit of saying "nna" (んなぁ) in their speech.
