I bought a new ONE PIECE manga volume 63.
Removing its jacket, we can find a message saying "Don't be gloomy if you're my crew!!! Cheer up!!!" like this.
And the record for the most copies in its first printing was broken - Japanese publisher Shueisha is producing 3.9 million copies of the 63 volume.
There is no sign of an end to its long-term popularity.
