What this is

The Shimotsuki Codex is a free, non-commercial fan reference for One Piece. 28+ years of canon across 1,181 chapters, 112+ volumes, and nearly three decades of SBS — scattered across sources that don't always agree with each other.

The Codex puts it in One Place, sourced, cross-referenced, and tiered by trust level. Eight surfaces, all linked together:

Status legend: Live stable · Maturing works but rough edges · Planned on the roadmap

Built by Shimotsuki Kajiya, with Claude as pair programmer. Forging clarity from chaos.

The Canon Engine — what makes the Codex different from the wiki

The Fandom wiki is a useful starting point but cannot be the source of truth. It carries speculation creep, translation drift, edit wars, and circular citations. The Codex's purpose is to be the verification layer the wiki should be but isn't: every claim traceable to a primary source, with a tier badge that tells you exactly how trustworthy it is.

Five tiers, each with its own visual treatment so the trust level is readable at a glance:

In SBS Q&As and theory bodies, recognised references auto-link with a colour that tells you who said the surrounding sentence: Oda's words get gold, a reader's question stays neutral grey, and a theorist's claim reads as ink-blue speculation. A link is navigation — not endorsement of the surrounding sentence. See canon-policy.md and canon-engine-roadmap.md for the rules in detail.

Coverage notes

The Codex covers everything that exists — but a few notable gaps in the source material itself:

How it works

Every page is a static HTML file with all data baked in. Hosted free on GitHub Pages. No backend, no database, no tracking, no signup.

Privacy

No accounts. No tracking. No cookies set by this site. No analytics. Your settings, favourites, and search history are stored in your own browser's localStorage and never leave your device.

This site loads images from the One Piece Fandom wiki and reader avatars from this repo. That's the only passive network activity besides loading the page itself.

Submission forms. The Curate, Corrections, and Theory Workbench pages submit to GitHub Issues via the public GitHub API. If you choose to submit a correction or theory, your submission becomes a public issue on the project repo, attached to your GitHub identity if you are signed in. If you would rather stay anonymous, do not use these forms — read-only browsing collects nothing.
