"Oh no, oh no, oh no! My deadline! How long was I sleeping!?"

— Tetsuya, Dr. Stone (Manga), Chapter 82

Tetsuya Kinomoto ( (きの) (もと) (てつ) () Kinomoto Tetsuya), also known as Mr. Mangaka, is a modern member of the Kingdom of Science. Prior to the Petrification, he was a manga artist. He was revived to test the feasibility of reviving a broken statue, and was later tasked with helping bring back entertainment to the Stone World.


Tetsuya is a short man with extremely short hair and an egg-shaped petrification mark on his scalp. He has large, round eyes with heavy dark rings underneath, from lack of sleep. His skin is slightly pasty-looking, as if he hadn't been in the sun much. His nose is wide and flat, and his eyebrows are small and thin. His ears are also very round and protrude quite a lot, giving him a slightly monkey-like appearance. When he opens his mouth, he tends to have a droopy, "3"-shaped upper lip.

He wears a deep red bow tie and a plain beige short-sleeved shirt with no buttons and tied at the waist with a pale green bow. His pants are a slightly darker green and cropped, exposing his leg midcalf. He's also got sack-like leather shoes with dark soles.


Tetsuya is very dedicated to his former occupation as an artist: the very first thing he did after reviving was ask about his project deadline, unaware of the centuries that passed.[4] He has focused so much on being an artist, that he ended up not being good at much else.

Due to his manga artist background, he noticed many small bits of trivia. This was seen when he was giving a play-by-play of the aerial battle between the Kingdom of Science and American Colony thanks to one of his previous works, a military series named "WW4".[7]

In Dr. Stone: The Voices That Face the Future, Tetsuya also believed that porn accelerated human progress, and was a necessity no one other than Ginro was man enough to ask for. He was ready to develop a porn industry with Ginro's help and take over the world, making a ton of money, but the plans were stopped by Kinro before they could come to fruition. He was also shown to be basking in the glory of having no deadlines, but still helped Gen and Ruri with writing an interesting story. In addition, he was trying to develop wordless comedy mangas so that the illiterate villagers could enjoy them as well.

Later in the same story, Tetsuya expresses his gratitude to Senku for healing his artist injuries and allowing him to continue his work. He also took on Namari as an apprentice, but still advised her to continue going to school with her other friends.

Abilities and Skills[]

Most of Tetsuya's skills are related to his manga drawing.

  • Drawing Abilities: As a mangaka, Tetsuya is a pretty talented artist. There's several instances in which he's done work for the Kingdom of Science, such as when he drew them a detailed map of the forest by the river,[8] and created them a sign with the help of Namari. When Ryusui created currency, Tetsuya was seen selling people their own manga, that even moved some to tears.[9]
  • All-Nighter Skills: Shown in his character design and in his character profile, it's clear Tetsuya is somewhat of an insomniac. When Tetsuya awoke, he was incredibly worried about his deadline,[4] so it can be assumed that Tetsuya has spent several sleepless nights drawing manga.
  • Esoteric Knowledge: In his years of drawing manga, he has come to draw many different types of genres. And in doing so, he has picked up little bits of knowledge in these fields. This is shown when he comments on why the planes are circling each other, due to having drawn a military series before.[7] He also later comments on the faxing by saying how another manga artist used a similar technique to draw manga abroad.[10]


It would seem that in the Stone World, a lot of Tetsuya's problems ceased.

  • Deadlines: Upon waking up, Tetsuya immediately fears for his deadlines, and doesn't even notice how much time has passed, showing how important the deadlines are to him.[4]
  • Tiredness: Tetsuya suffers from massive bags under eyes, which have been caused by the many all-nighters he has taken in order to finish his deadlines.
  • Low Earnability: According to Tetsuya's worker file, he doesn't get a lot of money for his hard work reaching deadlines.

Tetsuya's stats, according to Volume 10


In the pre-petrification world, Tetsuya worked as a mangaka, and was pretty good at what he did, at least by the people who recognized him and his talents. Despite his skills, he made very little profit from his work. He was probably extremely overworked, with constant deadlines that he spent many sleepless nights working to complete. Over the years, the all-nighters took a toll on Tetsuya, forming permanent large bags under his eyes.

Throughout his life, Tetsuya would work on many different genres and manga series, one named example being a military series titled "WW4".[7] While working on these series, Tetsuya would pick up little tidbits of information and fun facts on said genre. He also learned about other mangakas such as Osamu Tezuka.

When he was petrified, Tetsuya was working on yet another one of his projects, and thus his resulting petrified position was him working hard at his desk.


Communications Arc[]

Tetsuya's statue is pieced back together by Yuzuriha before being revived. His first reaction was to worry about his deadline and asks how long he's been asleep for, to which Kaseki informs him that it's been several thousand years. Tetsuya then laments how his draft is very overdue. To stop him panicking more, Gen hands him a piece of paper, telling him he can get right back to drawing manga. He is then told that he was revived to begin bringing back modern entertainment.[11]

Age of Exploration Arc[]

During the boat designing competition, Tetsuya mentions that he helped Magma draw up his final boat design.[12] Despite helping Magma, he still chose Senku's design in the end. After Ryusui reinvents money in the form of Dragos, Tetsuya is shown creating and selling manga at 100$ apiece, something the modern timers enjoyed.[9] He also helped Namari make and set up a sign for the Kingdom of Science's tactics chamber.[13]

New America City Arc[]

Sand Table

Tetsuya creates a diagram.

While in America, Tetsuya drew a detailed layout of the forest, the Perseus, and distance to the enemy castle using painted hexagonal tiles to act as a war table. Matsukaze remarked that his work made war planning much easier to follow.[8]

Tetsuya later witnessed and explained the aerial battle between Senku and Ryusui versus a member of Stanley's unit. Minami remarked that he was oddly talkative while it was happening. Tetsuya makes remarks throughout the battle, describing the piloting skills on display as well as the risks the pilots were taking in such primitive planes, and reacting to the danger the pilots are facing.[7][14] He was later captured by the Americans along with the rest of the Kingdom in Corn City.

South America Arc[]

When Chelsea faxes a map to the members of the Kingdom in Corn City in order to locate the Rodex headquarters, Tetsuya remarks on how another manga artist, Osamu Tezuka, did a similar thing in order to draw manga while abroad.[10]
