How many Dorohedoro books are there?
Twenty-three volumes, 167 chapters, and a bonus chapter hiding inside every single book.
The short answer is 23 volumes. The full count runs deeper: 167 numbered chapters, labelled Curses, plus a short Bonus Curse extra chapter in every volume, and one 14-page special chapter published in the magazine in February 2020, seventeen months after the ending.
Every volume below carries its Japanese and English dates, its page count, the cast on its cover, and both ISBNs. The two companion books, the All-Star Directory and the Mud and Sludge art book, have their own page in this archive.

READING THE CENSUS
What the numbers showThe shape of the run
The early books are slim, 160 to 200 pages. From volume 15 they thicken past 200, and the finale is the biggest object in the series: 352 pages, twelve chapters and the special chapter’s companion pieces gathered in.
The twenty-month gap
Between volume 19 (January 2014) and volume 20 (September 2015) there is a hole in the shelf. That gap is the death of Monthly Ikki, measured in book form.
The ISBN trail
The Japanese ISBNs run in a near unbroken block, 978-4-09-188271-4 through 978-4-09-188693-4, with the block jumping at volume 17. The English ISBNs switch publisher prefix at volume 22, from 978-1-4215 to 978-1-9747, a fingerprint of Viz’s own renumbering era.
