About Dr. Stone
Dr. Stone is a Japanese manga written by Riichiro Inagaki, the writer of Eyeshield 21, and drawn by the South Korean artist Boichi. It ran in Shueisha's Weekly Shonen Jump from March 2017 to March 2022, and its 232 chapters were collected in 26 volumes, with a 27th volume of extra stories following in 2024. Viz Media publishes it in English, and by March 2026 it had more than 20 million copies in circulation. TMS Entertainment's anime ran from July 2019 to June 2026: four seasons (the first season, Stone Wars, New World and the three-part final season Science Future) plus a TV special, Dr. Stone: Ryusui, with 94 TV episodes in all. Shinya Iino directed the first two seasons and Shuhei Matsushita the special and the last two.
One day in 2019 a green flash turns almost every human on Earth to stone. Some 3,700 years later Senku Ishigami, a teenage science prodigy who kept his mind awake by counting the seconds, breaks free into a world where the cities have crumbled and forest has taken over. He works out that nitric acid from a bat cave set him free, and with his best friend Taiju he turns it into a revival fluid. The first person they revive is Tsukasa Shishio, a martial artist who wants a fresh start for the young without the corrupt adults of the old world, and who starts smashing their statues. Senku means to bring back everyone and all of science with them, and the two become enemies.
From there the story is a race through the history of science. Senku finds Ishigami Village, whose people are descended from his father's astronaut crew, and leads them from iron and electricity to glass, medicine and a mobile phone, then into a war with Tsukasa's Empire of Might that he tries to win without killing anyone. Later seasons send the Kingdom of Science to sea in an oil-fuelled ship, to an island ruled with a petrification weapon, and across the Americas, where a rival scientist has built his own army. All the while, a radio signal asking "Why?" suggests that someone turned the world to stone on purpose. Much of the science is real, and reviewers have noted its accuracy; MythBusters' Kari Byron praised much of it while pointing out where it takes liberties.

What the Dr. Stone Quiz Tests
Our Dr. Stone quiz covers TMS Entertainment's whole anime (season 1, Stone Wars, the Ryusui special, New World and the final season Science Future), which adapts all of Inagaki and Boichi's manga. It does not ask about the Reboot: Byakuya and 4D Science spin-offs or the Terraforming one-shot. Easy levels cover the premise and the core cast: the 3,700 years in stone, the revival fluid, Tsukasa's plan, the people of Ishigami Village and who made the series. The middle levels follow the inventions and the story in order: lightning-made magnets, the silver spear and the sulfa drug, the Grand Bout, Byakuya's glass record, the phone, the Steam Gorilla and the battle for the Cave of Miracles, then the oil field, the "Why" signal, Treasure Island and Dr. Xeno. The hard levels go to the details: the year Senku wakes, the mineral that gives him tungsten, where the names Senku and Byakuya come from, the band behind the first opening, the Five Wise Generals and two questions from the final season.
Key Characters
Senku Ishigami is a hero with no powers at all, only an enormous knowledge of science and the patience to rebuild it one step at a time. He likes to sound cold and calculating, and Tsukasa sees straight through it: Senku's real weakness is that he will not abandon a friend. His partner in almost everything is Chrome, a villager who had been teaching himself chemistry from rocks long before Senku arrived, and who grows from apprentice into an inventor in his own right. Kohaku, the village's best fighter, gives the Kingdom of Science its muscle and its sharpest eyes; Gen Asagiri, a mentalist who changes sides for a bottle of cola, gives it its voice. Taiju, Senku's tireless and gentle best friend, and Yuzuriha, whose craftwork holds a great deal together, are the friends Senku is fighting for. Across from them stands Tsukasa Shishio, a fighter who wants a new world for the young and is not wrong about everything, which is why his rivalry with Senku carries the first two seasons. Behind them all is Byakuya, Senku's astronaut father, whose stories and gifts shape the story long after his death, and later Dr. Xeno, the mentor who became Senku's rival.

Dr. Stone Fun Facts
- Dr. Stone was one of several story ideas Inagaki took to his editor, who picked it because he had no idea how it would develop. Inagaki was already a fan of Boichi's art, and Boichi was approached about drawing it around the time the storyboards for chapter three were finished.
- Senku was originally named Gaku, meaning "study". Inagaki found that too academic and changed it to Senku, "thousand skies", the counterpart of his father Byakuya's "hundred nights". Season 1, episode 17 is titled "A Hundred Nights and a Thousand Skies".
- Inagaki based Senku partly on Agon Kongo, an antagonist from his earlier manga Eyeshield 21: he likes that curt, no-nonsense type and wanted to give it a positive role.
- Boichi studied physics at university, choosing it as preparation for drawing science fiction.
- Senku's catchphrase "This is exhilarating!" made Gadget Tsushin's list of 2019 anime buzzwords, and Senku won Best Protagonist at the 4th Crunchyroll Anime Awards in 2020. The manga won the 64th Shogakukan Manga Award in the shonen category in 2019.
- The series finale closes with "Good Morning World!" by Burnout Syndromes, the song that opened episode 1 back in 2019. The same band also performs "Rocket", the ending theme of the final part.
