Start with volume 1, and settle the edition question before you buy anything, because that is where readers of this series actually go wrong. This path follows Viz's original 22-volume single-volume run, which our catalogue lists beginning with 20th Century Boys. The later Perfect Edition compresses the same chapters into eleven fatter books under different numbering. Either edition is fine on its own terms. Mixing them is not: buy a Perfect Edition volume 4 after a single volume 5 and you will conclude you have lost a hundred pages, which in effect you have.
There is no clever alternative entry point. Naoki Urasawa builds the entire mystery out of withheld chronology — he cuts between 1969 and 1997 with no captions and expects you to date a scene from haircuts, cars and shop fronts alone — so every later reveal depends on having met the childhood versions of these people first, in the order he gives them. Read volume 1.
Volumes 1 to 5: the symbol
20th Century Boys opens on Kenji, a failed musician minding a convenience store and his sister's baby, and it takes its time. The hook lands in volume 3, when a childhood drawing turns up attached to a real death, and the pace never slackens afterwards. Five volumes is roughly a week; most readers do two or three in an evening once they are past the opening.
Volumes 6 to 10: Bloody New Year's Eve
This is one continuous set piece split across five spines, and the best argument for reading the series quickly. A gap that is ours rather than the series': our catalogue does not currently carry volumes 6 and 8 of this edition, so the path page shows 7, 9 and 10 for this stage. The story runs 6-7-8-9-10 with no skips. Buy the two missing volumes wherever you normally buy books and read the run intact.
Volumes 11 to 14: Kanna's world
Volume 11 changes lead, decade and cast, and explains none of it. The first fifty pages are the most disorienting in the series, and that disorientation is engineered — do not go back and reread earlier volumes to fix it. Two more catalogue gaps to name plainly: volumes 12 and 13 are not currently in our catalogue either, so the path page shows 11 and 14 only. Read 11-12-13-14. Volumes 12 and 13 are where the second-generation cast is assembled and old faces are reintroduced under new names, and volume 14 assumes you have met them.
Volumes 15 to 18: where readers stall
The plotting gets denser rather than faster here, and volume 17 in particular hands out information at a rate that punishes twenty-page phone sessions. Give it four evenings, one volume each, and finish 18 within a week of starting 15 so the identity material stays in working memory. If you are going to abandon the series, this is where it happens, and the honest answer is that pushing through is worth it.
Volumes 19 to 22, and the part that is not here
Read the last four as one long final act. One more gap: volume 20 is not currently in our catalogue, so the path jumps from 19 to 21. That is our shelf, not Urasawa. And the main run does not quite finish the story — one thread is left open in volume 22 and closed in the two-volume coda 21st Century Boys, which we do not carry either. Budget those two extra volumes if you want the complete ending. Readers are split on whether the coda improves the finale or merely explains it; most think it is necessary.
Singles or the Perfect Edition?
If you are buying new, the Perfect Edition is the easier object: hardcover, larger pages, better paper, fewer spines. If you are buying secondhand or reading library copies, the singles are far easier to find complete. The one thing not to do is start in one and finish in the other. Whichever you pick, the reading order is simply first to last — and the stage-by-stage breakdown, with study notes for each arc, is on the 20th Century Boys hub.
