So I've checked the Video of the Italian YT and their visit at Shueishia studios :
- There isn't too much difference between the editor of a mangaka and the Media Editor
- Oda basically decide everything even if an editor doesn't like an idea, if Oda want to do it in that way He will.
- They asked Naito realistically how many years are left for the end of the Manga, He answered " 5 years or even less ".
- They talked also about some stuff related to Shueisha work place and what an editor actually do.
- They had also an interesting interview with the Boss of Shueisha, the interview will be released soon on their YT Channel.
