How is the Demon Slayer manga collected?

The core collection is simple to state: 205 chapters, 23 volumes, published by Shueisha in Japan between 2016 and 2020, with the final volume released in December 2020. Each Japanese volume carries a cover built around one or two characters in Gotouge's watercolour influenced colour style, over a patterned ground, and the spine design forms a consistent run that reads clearly on a shelf even in Japanese.

Viz Media published the English edition in 23 matching volumes between 2018 and 2022, then gathered them into a complete box set with a poster and an exclusive mini book, which is now the standard English shelf form. English single volumes were printed in large numbers at the height of the boom, so reading copies are plentiful, while the box set's extras are the part that disappears first on the second hand market.

Around the main run sits a defined support shelf. Two official fanbooks document the Corps, its members and the story's background, with author involvement. Short material includes the Rengoku and Tomioka side stories, the Kimetsu Academy spin on the cast, and collected one shots, several of which were bundled into the fanbook and special editions rather than sold as standalone volumes.

Completion checks for buyers: a full Japanese run should be checked volume by volume for obi bands if you care about them, since they were not consistent across reprints, and English box sets should be checked for the poster and mini book, which are routinely missing. The series' shortness is its collecting virtue: unlike most Jump hits, a genuinely complete Demon Slayer shelf is a realistic goal.
