Demon Slayer: Kimetsu no Yaiba – One-Winged Butterfly

Demon Slayer: Kimetsu no Yaiba – One-Winged Butterfly is a light novel written by Aya Yajima and set within the world of Koyoharu Gotouge's Demon Slayer: Kimetsu no Yaiba. Released in 2019 as a single volume, it collects six short stories that step away from Tanjiro Kamado's central journey to focus on the Demon Slayer Corps and the figures around it, including Hashira and other supporting characters. The book is episodic in structure, with each tale standing largely on its own while sharing the parent series' blend of action, drama, and supernatural stakes.

The story sharing the volume's title follows the Kocho sisters and the path that led them to join the Demon Slayer Corps. Elsewhere in the collection, Uzui pushes Zenitsu toward finishing his training by holding out the promise of a mixed-gender bath, an offer that prompts Zenitsu to rope in Inosuke for assistance. Another story turns to Mitsuri, who becomes troubled after learning why Shinobu joined the Corps, starts avoiding the other Hashira, and leaves Obanai and Shinobu puzzling over how to lift her spirits.

Quieter material fills out the remaining pages, among them a piece in which Genya spends a calm day at the Butterfly estate with thoughts of his older brother on his mind. Across the six stories, One-Winged Butterfly leans on character history and everyday moments, giving members of the supporting cast room the main narrative does not always provide.

Demon Slayer: Kimetsu no Yaiba - One-Winged Butterfly (鬼滅の刃 片羽の蝶) is a light novel companion to the Demon Slayer: Kimetsu no Yaiba franchise. It was written by Aya Yajima, who is identified as the author of this second Demon Slayer light novel. The book was released in 2019 and is finished, comprising six chapters or short stories collected in a single volume.

Within the franchise's publishing lineup, One-Winged Butterfly is a prose work rather than an entry in Koyoharu Gotouge's main manga series. The supplied record lists Shueisha in connection with availability, and the source material is categorized as a light novel. Its six-part structure groups self-contained tales, distinguishing it from the numbered chapters of the main Demon Slayer manga.

Production details for this individual volume are limited in the saved record. It is a Demon Slayer light novel rather than a manga serialization, and no English edition, alternate adaptation, or expanded release history is confirmed in the available data. The work stands as a single-volume light novel release from 2019.

One-Winged Butterfly is a light novel within the Demon Slayer: Kimetsu no Yaiba franchise, not a mainline manga chapter or an adaptation of one. It belongs to the prose side of the series, a companion volume that expands the world around the core narrative rather than retelling it. The main franchise began with Koyoharu Gotouge's manga and grew through anime adaptations, films, and supplemental books; this entry sits in that supplemental group.

As the second light novel for the property, it follows the same franchise timeline and character set, but its short-story format makes it a side collection rather than a required continuation. Readers already familiar with the Demon Slayer Corps will recognize the setting and cast, while newcomers should not treat this volume as the starting point. It is best understood as an alternate-format addition to the franchise, offering standalone prose episodes that enrich established characters and organizations without replacing the primary manga storyline.

Within the broader franchise hub, this page documents a specific prose installment. It is not the beginning, nor a remake of the manga, and it does not replace the television series or films. Its relationship is that of a companion work: part of Demon Slayer's expanded publishing line, aimed at readers who want additional stories about the Demon Slayer Corps and the Hashira.
