This is probably insane, but here goes:

1 Pirate King

2 Ancient Weapons

3 Admirals

4 Yonkou

5 Blackbeard Pirates

6 Logia Users

7 Shichibukai

8 Strawhats

9 Cipher Pols

10 Years since Luffy ate the Rubber Fruit

11 Wanted Crewmembers

12 Baroque Works Levels

13 ….

Damn.

Basically, the theory is to include any significant grouping up to 22. 22 is henceforth the magic number, as it correlates to Roger's Death. Why 22? Why not 20 years or 25 years? Why 22?

Now, I'm not insane and think that Oda is some brilliant numerologist, but there has to be an underlying logic behind the numbers. If you can discover it, you've broken the code of One Piece.

Or maybe I've just gone insane.

Either way, what numbers can you guys come up with from the manga that eventually total 22? I've provided ones up to 12, but 10 isn't so great (there's probably a better one), and there's 9 others I can't solve.

So, have at it.
