Demon Slayer Name Generator

Demon Slayer is set in Taisho-era Japan (1912 to 1926), and its names sound like it. Human characters use a real Japanese given name followed by an unusual, often archaic surname: Tanjiro Kamado, Giyu Tomioka, Kyojuro Rengoku, Tengen Uzui, Sanemi Shinazugawa. Koyoharu Gotouge picks surnames that are rare in modern Japan and heavy with imagery, such as Rengoku (purgatory), Kamado (hearth), Kocho (butterfly) or Himejima, and given names that lean old-fashioned: Zenitsu, Inosuke, Gyomei, Obanai, Muichiro. Female names like Nezuko, Mitsuri, Kanao and Shinobu are equally period-flavoured.

Demons follow a different rule. Once turned, most abandon their human name for a single, ominous word, frequently written in unusual kanji: Akaza, Doma, Kokushibo, Enmu, Rui, Gyokko, Nakime. Their old human names surface only in flashbacks (Akaza was Hakuji, Kokushibo was Michikatsu Tsugikuni), which is a great device to copy for a demon OC. Nameless lower demons are simply called by their form: Hand Demon, Swamp Demon, Spider Mother.

Corps ranks and Hashira titles sit in front of the full name (Water Hashira Giyu Tomioka; Kinoe, Kanoe, Mizunoto), and each Hashira's breathing style should be echoed in imagery around them, so a Frost or Moon Hashira OC benefits from a surname with snow or moon kanji, like Yukimura or Tsukishiro.
