Dr. Stone ended its run on June 25, 2026, after four seasons and 94 episodes. The anime, produced by TMS Entertainment, first aired on Tokyo MX on July 5, 2019, and closed out its final season, Dr. Stone: Science Future, with a third and last cours that ran from April to June 2026. That is seven years from premiere to finale for a show about a teenager with a chemistry set and no electricity.
The premise is simple and strange. A green flash petrifies all of humanity in June 2019. Senku Ishigami, a 15-year-old prodigy, wakes up in April 5738 — 3,719 years later — to a world where every trace of civilization has been worn down by time. His friend Taiju Oki follows six months later. Together they work out that nitric acid made revival possible, and the race to rebuild the world with science begins.

Senku Ishigami and the Kingdom of Science
Senku is the engine of Dr. Stone. He is voiced by Yusuke Kobayashi, and the show asks him to carry both the comedy and the actual problem-solving. The series treats science as a series of steps: find the materials, build the tool, survive the night. That structure is why Dr. Stone works. It is not a show about power levels. It is a show about process.
The supporting cast fills out the world. Makoto Furukawa voices Taiju, Kana Ichinose voices Yuzuriha Ogawa, Manami Numakura voices Kohaku, Gen Sato voices Chrome, Kengo Kawanishi voices Asagiri Gen, Ryota Suzuki voices Nanami Ryuusui, and Karin Takahashi voices Suika. The ensemble is large, and the show uses it to keep the rebuilding plot moving across four seasons.
Tsukasa Shishio and the Fight Over the Old World
The best conflict in Dr. Stone is not the petrification. It is Tsukasa Shishio, a famous high school martial artist revived early on, who turns against Senku. Tsukasa believes the old world was tainted and should not be restored. He wants a new order built on power and strength, and he destroys petrified adults he finds so they cannot interfere.
That disagreement gives the series its spine. Senku wants to bring back everything — antibiotics, electricity, the whole chain of human knowledge. Tsukasa wants to start over and leave the past in the ground. Both positions are clear, and the show does not pretend the second one is stupid.
The series synopsis sets the opening plainly:
One fateful day, all of humanity was petrified by a blinding flash of light.
The adaptation has a clean production history:
- Season one aired from July to December 2019
- Season two, Dr. Stone: Stone Wars, aired from January to March 2021
- The television special Dr. Stone: Ryusui aired in July 2022
- Season three, Dr. Stone: New World, ran its first cours from April to June 2023 and its second from October to December 2023
- Season four, Dr. Stone: Science Future, ran cours from January to March 2025, July to September 2025, and April to June 2026
Riichiro Inagaki, Boichi and the Manga Behind It
The source material was written by Riichiro Inagaki and illustrated by Boichi. It ran in Shueisha’s Weekly Shōnen Jump from March 2017 to March 2022, collected in 27 tankōbon volumes. Viz Media licensed it in North America, and Shueisha began simulpublishing it in English on Manga Plus in January 2019.
Twenty Million Copies and a Shogakukan Award
Dr. Stone won the 64th Shogakukan Manga Award in the shōnen category in 2019. By March 2026, the manga had over 20 million copies in circulation. Those numbers matter less than what they represent: a manga that ran five years and an anime that then ran seven, without either one changing its central idea.
The show’s genres — animation, action and adventure, comedy, sci-fi and fantasy — describe it accurately, which is rarer than it sounds. Dr. Stone is funny without undercutting its stakes. In our view it is a science show that respects its own rules, and when Senku builds something, the episode has generally laid out the materials first.
What Dr. Stone Gets Right
The final season had to land a story that had been running since 2019, and it did so on its own schedule, across three split cours. That is not a small thing. In this paper’s view, anime finales too often rush. Dr. Stone: Science Future spread its three cours across January 2025 to June 2026, and the structure suggests the production knew what it was doing.
The weakness is pacing. Four seasons and 94 episodes is a lot of ground to cover, and the middle stretches — the tribe, the Kingdom of Science, the repeated material-gathering arcs — can feel like a loop. The show’s formula is a strength until it is not. A viewer who bounces off the first cour will not be converted by the third.
But the formula is also the point. Dr. Stone argues that civilization is not a thing you inherit. It is a thing you rebuild, one experiment at a time, and it takes thousands of years or a few determined teenagers, depending on who is counting. That is a real idea, and the series commits to it from the first episode to the last.
The published audience score for Dr. Stone stands at 8.5 out of 10, drawn from 1,787 votes on TMDB. That tracks. It is not a perfect show, and it does not need to be. It is a long, patient, genuinely curious series about a boy who refuses to let the lights go out.
