002 - Senku Ishigami

He shares characteristics with Yoichi Hiruma from Riichiro Inagaki's previous series, Eyeshield 21.
Smiling while navigating the best situation to achieve your goals.
High intelligence, photographic memory, and cunning.
Proficient in arithmetic, capable of calculating long periods of time down to the last second.
Senku's bowel movements before petrification were quite regular.
He is allergic to hairspray, to the point that his face swells up considerably.
In the Portuguese dub, the pronunciation of the name Senku was changed because "Senku" means "without a butt".

In chapter 51, when Senku asks Gen about Homura, Ginro, Pá, and the Sisters assume he's asking about her romantically. Later, he rejects any attempts to take advantage of Homura after catching her.
After Senku promises Nikki that he will protect Lillian Weinberg's last recorded song, Nikki also states that she could fall in love with him, something he advises her not to do.
He was immune to Amaryllis's charms.
Kohaku kissed him, but neither of them seemed to like it.
He charms Luna to get information from her and leaves her with a crush on him, after which Luna asks if he will be her boyfriend. The team comments that it's not like he's exploiting these deals solely for his own benefit.
He mentions
Doraemon
as one of the things about modernity that he liked, rejecting Tsukasa's suggestion of reverting humanity to a tribal state.
He demonstrates a love for video games, making references to Super Mario Bros., Civilization, Dragon Quest, and Monster Hunter (Monster Hunter receives a special mention in chapter 63).
He has three main catchphrases: he says "10 billion percent" when he's sure of something, "Not a millimeter" to state how impossible something is, and "That's exciting" (or "Get Excited" in the English dub) when a new development occurs or he manages to advance in his scientific developments.
A recurring joke involves Senku's previous marriage and divorce being mentioned:
When Hyoga approaches Senku to form a partnership, Senku tries to escape by asking if that was his version of an embarrassing love declaration, and then states that he is married (and later corrects himself by saying that he is now divorced).
When Amaryllis asks about Chrome's relationship with Ruri, François points out that Ruri was previously married to Senku before his divorce, shocking Taiju and Amaryllis.
When Luna asks François about going out with Senku, Kinro mentions that Senku is divorced, much to Luna's shock.

Senku's name is composed of "sen" (千, thousand) and "kū" (空, sky) to create Senkū (Thousand Heavens). Ishigami is composed of "ishi" (石, stone) and "kami" (神, god) to create Ishigami (God of Stone).
Senku shares a motif with Taiju and Yuzuriha, as his name contains "kū" (空, sky), which relates to the theme of "earth, sea, and sky".
Senku's first name is a counterpoint to that of his father, Byakuya. Senkū (千空) means a thousand heavens, while Byakuya (百夜) means a hundred nights. This is exemplified in the title of chapter 44 of the manga and in episode 17 of the 1st season of the anime; 百の夜と千の空 (A Hundred Nights and a Thousand Heavens).
On the day Senku was born, January 4, 2004, NASA's Spirit rover landed on the planet Mars.
His biological parents passed away suddenly in January 2006, when Senku was only 2 years old.
Senku ranked 1st in both the 1st and 2nd Character Popularity Polls.
Senku's original name was going to be "Gaku Shiraishi" and would have used the kanji for "study" (学), but it was changed because Inagaki thought it sounded too academic.
There were women who showed signs of attraction to him (or who, in some way, were involved with him in various circumstances):
Kohaku claims to have fallen in love with him at first sight, which disturbed him. Although she clarifies that it's a platonic relationship, she later admits, in chapter 22, that to her he seems like "a real charmer," but not in a way that the brilliant sisters could appreciate.
An extra page in Volume 7, concerning Kohaku's comments about him, questions what the high school girls who knew him back then thought of him. One of them said, "The white lab coat is sexy."
Ruby states that she is interested in a man who will pamper her, and is so impressed with the ramen Senku prepares that she asks what type he is.
He marries Ruri, but divorces her almost immediately. Besides, she had no feelings for him.

Bad Luck: Throughout the series, despite his high intelligence and ability to overcome obstacles, he tends to get into trouble frequently due to his terrible luck. Gen, at one point, comments to Senku (while they are trying to manufacture gunpowder to stop Tsukasa's army and fail) that Senku always has terrible luck. In the Petrification arc, when he goes to Treasure Island, after all his resources and options have been exhausted while he and the Kingdom of Science are cornered by Ibara, Moz, and their army, Senku is even forced to use his worst card up his sleeve—resurrecting Hyoga (a rather unpredictable and cruel man willing to manipulate and kill anyone in his path) to have a chance to fight Ibara and Moz, despite the strong possibility of Hyoga immediately dominating the Kingdom of Science and/or discovering the petrification device afterward. Later, Ibara uses the petrification device to petrify everyone except himself. While detailing their journey through the Vikings, a storm hits the group, but they still manage to reach America, thanks to Chrome. As they begin exploring the United States, the team is attacked by alligators while Gen, once again, comments on how Senku's luck is nonexistent and each of his worst-case scenario hypotheses usually turns out to be true.

Intermediate Craftsmanship: Senku's crafting skill is good enough to manufacture usable objects and tools, but he largely had to work hard to reach this level. Although Senku is knowledgeable about a wide range of crafting methods, many of them he had never used before petrification (such as pottery, stone toolmaking, or glassblowing), which leads him to have shortcomings due to inexperience, and he improves throughout the series, reaching practical skill levels in all the aforementioned tasks. Still, his aspirations for the Kingdom of Science benefited from relying on more experienced craftspeople to build things more quickly. Although Kaseki was initially called upon for the specific task of glassblowing, Senku still developed this skill on his own, as shown when he made glass utensils after Suika revived him alone in the Amazon rainforest.
Lack of Cooking Skills: While not exactly a weakness, he is not an exceptional cook. He is shown to know how to cook, but lacks experience and quality ingredients. Although he understands the food preparation process, most of the time, more complicated foods don't taste good. While he managed to make cotton candy and soda, more complex foods like wine, ramen, and bread proved to be terrible in taste. In the case of ramen, part of the problem is the absence of the exact ingredients (he uses foxtail to make flour instead of wheat). When he tries to make bread with all the proper ingredients for the first time, the result is so awful that no modern person could eat it (although the Ishigami Village tribe loves it, as they had only eaten fish and had never tasted bread before).

Incomplete Knowledge: Although Senku possesses an unbelievable amount of knowledge about science and technology, it should be noted that he doesn't know everything with the level of detail it might seem. Instead, he sometimes seems to fill in the gaps with his well-informed scientific thinking and experience. This, however, has on several occasions caused him to face difficulties with problems he lacked knowledge of, or things he never knew how to do in detail. An example of this would be the manufacture of stone tools. Although he had a general idea of ​​them and how to manufacture them, he had to discover the specific techniques through trial and error. He was also unaware that carbon filaments don't work in vacuum tubes, and mistakenly thought it would be practical to manufacture the Steam Gorilla's engine with only one cylinder, which he eventually corrected.
Low Physical Aptitude: Senku is below average in terms of physical ability, lacking physical strength. He couldn't hold onto Homura, a small woman under 1.50 meters tall, after managing to grab her. He also admits he wouldn't stand a chance against someone as strong as Kohaku in a fight (though not a fair comparison given her training and warrior status). In a bonus chapter, Kohaku gives a brief description of the main characters' physical abilities. Senku is at the bottom with around three points, Chrome with five, Ginro with 100, Kinro with 500, and Kohaku herself with 1000. Similarly, Senku has low stamina and tends to become physically exhausted very quickly. He is also very vulnerable to hypothermia, only able to withstand cold water for a short period of time. Before his journey to space, Senku needed to train until he could develop a minimum level of strength.

Language Proficiency: Senku appears to be fluent in both Japanese and English. Initially, he had difficulties with English as a child, but over time he became more proficient thanks to his travels. He understood Ukyo and Gen while they were speaking English through the phone buried to conceal their conversation from others present. He was able to understand and participate in the discussion between Taiju and Dr. Xeno without problems. He understood and communicated with Dr. Brody without difficulty. During the trip to South America, Senku (along with Ukyo, François, Tsukasa, and Ryusui) acted as the group's translator, which consisted of Japanese and English speakers.
Morse Code: Senku is very familiar with Morse Code, using it to communicate with the cell phone team in order to capture Homura.

Tactical Intelligence: In addition to his scientific intelligence, he seems to possess some skill as a strategist. He managed to coordinate the villagers and even some of Tsukasa's army, whom he converts to his side in an effective and bloodless war against Tsukasa's Power Empire. Similarly, he manages to get Kohaku, Ginro, and Amaryllis to infiltrate the Treasure Island boss's harem as spies, and manages to communicate with Kohaku and develop a strategy to cunningly gather the scattered petrified pieces of his friends, along with the gemstones from the Soyuz capsule.
Exceptional Memory: Senku remembers all the compounds and methods of his inventions. He rarely makes mistakes in creating tools for the Kingdom of Science, and possesses vast knowledge in the aforementioned scientific fields.
Charisma: Although arrogant and eccentric, Senku seems to have a good understanding of people and how they think. He uses his many creations to charm those who were distrustful of him (such as ramen, glasses, and medicine) so that they gradually gain affection for him. Senku is also a capable leader, who knows how to use words, being able to motivate and lead the villagers into an effective army against Tsukasa's Power Empire. He personally earned the loyalty and respect of his allies (and enemies) through hard work and determination.

Genius Intelligence: Senku Ishigami is a genius with an encyclopedic knowledge of all scientific subjects. He is versed in chemistry, physics, engineering, geology, biology, and mathematics. Senku is able to easily create various useful tools and devices, medicines, and most notably, the de-petrification elixir, despite the limited materials of the Stone World. Tsukasa calls him "the sharpest and most intelligent man in the world." Beyond his scientific knowledge, Senku also possesses great ingenuity and an analytical mind, seemingly never running out of options at his disposal. For what he lacks, he has an ally who can offer his strength. He also possesses great mental fortitude, capable of thinking quickly and remaining calm in the most critical situations. Among the current active characters, his mental resources are rivaled only by his former mentor, Dr. Xeno.
Mental Resilience: Although Senku lacks physical prowess, he fully compensates with his determination and persistence. For example, he maintained consciousness during his petrification and counted the time he was petrified until the very last second for almost 4 millennia. Gen Asagiri found Senku impressive upon discovering that Senku had recorded the date of his revival. He wondered how someone not only knew the day and year he was released, but stated that he already respected Senku. When he was petrified again three years later, he was prepared and began counting to maintain consciousness. After his second revival, he managed to deduce that seven years had passed.
Craftsmanship: As a child, he designed and built a functional miniature rocket, along with many other advanced and experimental machines. However, Senku doesn't compare to a master craftsman like Kaseki in terms of construction skills, as Kaseki has far more experience than him.

Senku is a straightforward, confident, and logical individual who also knows the limits of his abilities. His decisions are often based on his vast knowledge of science and the application of the scientific method. Senku never belittles those who have less knowledge than him; however, he has a habit of delving into complicated explanations in an attempt to teach others. Nevertheless, his enthusiasm for science motivates and inspires everyone around him to do better. Because of his charisma and caring nature, people tend to gather around him, allies and enemies alike. Senku is also capable of admitting his mistakes.

Senku has a very logical mind, believing that there is nothing that science cannot explain, even if it takes a long time to properly understand any concept through science.

Senku frequently breaks the rules, withholds information, and manipulates others to get what he wants. He often acts as if he is building inventions and using people for his own benefit, while in reality he creates for the benefit of others. Behind Senku's apparent arrogance and manipulative actions lies a genuinely altruistic and kind heart.

Senku is a thin, physically weak young man of average height with pale skin. He has white hair that fades to green at the tips, forming naturally spiky, soft ends. Two strands of hair fall across his face. He has piercing red eyes, thin eyebrows, a small nose, and a mouth that tends to curve into a mischievous smile.

Before being petrified, Senku was wearing a typical school uniform with a lab coat over it.

Senku Ishigami (石いし神がみ千せん空くう, Ishigami Senkū) is the main protagonist of Dr. Stone, and is a friend of Taiju Oki and Yuzuriha Ogawa. He was unpetrified half a year before Taiju, and eventually created the Resurrection Fluid with Taiju's help. In the Stone World, Senku's goal is to rebuild civilization and establish a Kingdom of Science.

As the first-place champion of the Grand Bout, Senku currently holds the title of Village Chief in Ishigami Village, where he is widely considered a legend thanks to the influence of the late Byakuya in the founding of Ishigami Village.

Senku is also the leader of the Kingdom of Science, providing ideas and initiative for their large-scale plans. Later, he receives another title as one of the Five Wise Commanders, as he was one of the five people on the boat who first heard the Why-man's message.
