So what if Alabasta has a sacred devil fruit: Hito no Mi, Model: Zaza/Rain God.
The location is hidden, sealed within the kingdom.
It's so powerful that no one seems to control it unless it's the chosen one, a female Nefertari with a D.
Now that we know Vivi has a D, she's the next user ✌️
We all theorized that Blackbeard might be searching for the Hito Hito no Mi, Chopper's devil fruit in the Drum Island.
But why?
Maybe because he already knew that his Devil fruit: Yami Yami no Mi, will not work on Nerona Emo:
The ability: Black Vortex (Kurouzu), and Devil fruit powers Nullification.
So he needed, human fruit to turned the the devil emo into human with just a slap!!!!
Because the king of the world might be using just a vessel body to go out of the world, that's why he is mindful of the time he is out, and he knows there's a limit.
The Kuraigana Island is a dark and gloomy place somewhere in the Grand Line, perhaps this is where the Nerona Dynasty used to reside.
Where Mihawk find his solitude, and this is a fitting place for Nerona Emo.
Wala ba Bike to work team, or delivery rider team to represent?
I keep reading three chapters since his reveal, over and over again.
His haki is described as heavy, and suffocating, even the Pirate veteran Scopper Gaban-san is startled, and amazed by it, because its his first time encountering it.
And Luffy reaction is spot on, as he can verify its negative trait, unlike Joyboy's, that only made him speechless, and amazed.
So what's the Sadboy's source of "evil" haki?
I bet it's from the slaves, that he can extract most of their will power, then turn it into his own haki: the suffocating, heavy, dark, and evil haki.
What could be the reasons why he is hanging skulls as accessories?, are they his previous vessels for he is no longer have a real body now, after 800 years?
What's it's purpose?, is he using it as storage, as you can see it looks like the upper part is sewn, perhaps like Brook skull?
Is it his previous companions?
what could it be?
Remember Big Mam's dream that according to her ruined by Lola's decision not to be wed with the Prince of Elbaf Loki?..
I think Road is the one who fell in love with Lola, and impersonate Loki.
I don't think Loki will ever be doing that shenanigans, he thinks highly of himself. He resent anyone, and any race, even the peaceful giant he also hates.
