Head director always stays the same? You sure about that?
There is one above all.. Meaning you have directors changing and alternating and there is the Chief of Staff Dragon Lol, he's that Dragon!
but regardless if I'm correct about the specific
The interview was DONE DURING WANO Arc
It was in Saudi expo, and because I speak Arabic, I was able to watch all of the interview
But many fans were concentrated about one line in which he talks about the importance of the fight between Luffy and Kaido and Big Mom in this arc. The bastard spoiled Big Mom incoming for Anime fans... luckily for us manga we knew hahaha
Also, there were many questions like "why do they not make an episode about cover stories from manga" and so many other questions that we fans wanted to ask... one of those questions were directed at him about if he knows the ending of One Piece or not... he said yes but Oda-san would be too angry if he said it Lol
So yeah... again.. it was a recent interview in last year.. and the interviewer is actually a very famous One Piece fan reviewer in Youtube... and there were audience in the interview...
