Still, with the series getting released on Blu-ray for the first time, extra promotion and reminders are probably a good thing.
This is also a case of better late than never as Viz Media brought this set out back in November 2020 and is just now getting the trailer online for it.
As Zhou mentions here, the Spanish Blu-ray releases (which were upscaled) were missing some of the opening theme songs as the rights were unavailable.
