In fact, he doesn't like acting like that. How? When he has to confirm his status.
Being a "Dragonborn", he has the same privileges as Tenryubito, with slight restrictions.
Sometimes he has to remind the commanders-in-chief of the Navy, or anyone from the Navy, not to touch him.
A hand kiss is the least he can demand as a recognition of his weight. (Even this he tries to avoid)
The fact that Shanks is Tenryubito seems particular to me (it's not a surprise at this point).
but there is something that leaves me uneasy and that is the potential knowledge of the God Knight's of the sacred land, or the knowledge in general that the culture of the celestial dragons occupies about Haki
and this is precisely reflected in Shanks and one of his techniques that was recently confirmed (use the conqueror's haki to hide his presence and prevent the opponent from usefully using future vision or basic observation haki)
What different uses does haki really have? At what point did Shanks learn to use it? Did he learn it from Garling perhaps?
They are a despicable culture, we cannot deny that, but the mysteries behind the celestial dragons (beyond the empty century), such as the management of their society, the Tequila Wolf bridge, and the fact that they are descendants of those who overthrew Buccaneers and Lunarians 800 years ago...
