" OP has five databooks until now, Red, Blue, Yellow, Green and Blue Deep.
Red is called Grand Characters.
Blus is called Grand Data File.
Yellow is called Grand Elements.
Green is called Secret Pieces.
Blue Deep is called Characters World. "
" Apart from Blue Deep, the other four were published before time-skip.
And all databooks are made/supervised/checked by Oda himself. "
You can check these here:
Anyway I got really interested in this particular part...
16. Haoshoku haki has three levels (examples used are before time-skip):
primary - Ace & Luffy (subconsciously); middle - Rayleigh (volitionally); advanced - Shanks (continuously).
I'm so intrigued by this and so curious I want Oda to answer this part oh and this part too is really cool to know:
3. Shiki the Golden Lion was as strong as Roger, chapter 0 is a part of OP, but not in the main storyline, instead, it's the history that has happened in OP. (not the film strong world.)
... but I'm not Japanese and I don't know how to speak japanese properly so I could send a letter for a future SBS xDD
