The good news is that a new trailer for “Demon Slayer” season 3 is out. It is not yet known when it will be released officially.
Officially called the “Swordsmith Village Arc,” the new trailer shows off the new villains to expect in the next installment. The hype will be all that is visible to most people, so any information about a release date will depend on speculations.
The best to expect is that the third season of “Demon Slayer” will be out somewhere between early to mid-2023. Although it would have been nice to see the third season in the fall of 2018, this was unrealistic due to many factors, including COVID-19.
“Demon Slayer” debuted in the fall of 2019 with the Mugen Train moving to roll out in Japan in the fall of 2020. Ufotable has been consistent with his work output so this further stirs the pot – meaning a coming in the fall could be nixed at some point.
Some footage from production shows it is going well, as you can see by the trailer. But this is by no means an indication of when “Demon Slayer” season 3 will commence.
There is also the question of what the Swordsmith Village Arc will be covering. An unscientific guess would be that it would cover chapters 100 to 127 of the manga.
This is unless there are other deviations. Tanjiro might be considering going to Swordsmith Village for a new weapon. This scenario could be possible considering that the village has an ancient weapon.
