After over a year since Dr. Stone: New World, the fourth and final Dr. Stone season will finally start airing next month. Dr Stone: Science Future is slated for January 9, 2025, and will be streamed on Crunchyroll. The final season will be split into 3 cours, so it will total around 36 episodes. Season 3 adapted volumes 11-16, and this new season will adapt volumes 17-27, so anything less than 30 episodes might feel rushed.
Besides the previous seasons, a special episode was broadcast in 2022, titled Dr. Stone: Ryusui. Despite being a separate animation, this one is canon and adapts chapters 84-89 (between seasons 2 and 3), which is an arc focused on maritime conglomerate heir Ryusui Nanami.
For those unfamiliar with Dr. Stone, the story starts in 2019 (which was “a near future” when it started serialization in 2017), when all humans are suddenly petrified, including Senku Ishigami, the protagonist. 3,700 years later (that would be the 58th century), he is revived out of nowhere. Human civilization is gone, but he decides to study the petrified humans in order to try to develop a cure.
TMS Entertainment produced every season, but seasons 1-2 were animated by 8PAN, while the third season was handled by Die4Studio. The director also changed in the third season, with Shuhei Matsushita (Deemo: Memorial Keys) replacing Shinya Iino, and he is returning to direct season 4 according to MyAnimeList.
Yuichiro Kido was the head writer in all seasons, but seems to be unconfirmed as scriptwriter for season 4. Tatsuya Kato, Hiroaki Tsutsumi, and Yuki Kanesaka seem to be once again in charge of the music.
