Senku Ishigami

石いし神がみ千空

Senku Ishigami is the main protagonist of Dr. Stone, and is friends with Taiju Oki and Yuzuriha Ogawa. He is known for his catchphrases, one of which is "Ten Billion Percent". He was de-petrified half a year before Taiju was, and eventually created the Revival Fluid with Taiju's help. In the Stone World, Senku wants to rebuild civilization and establish a Kingdom of Science. He was the first-prize champion in the Village Games, and currently holds the title of Village Chief in Ishigami Village, where he is widely a legend thanks the late Byakuya’s influences through out his founding village’s community. Senku is the de facto leader of the Kingdom of Science. Later, as a member of the Five Wise Generals, Senku provides the ideas and initative for their large scale plans; he councils with Chrome, Gen, Ukyo, and Ryusui before taking action. Senku is a slim, yet reasonably toned young man of average height with white (light green in the anime,) brush-like hair that spikes up, with two locks of hair that drape over his face, and sharp red eyes. Kohaku admitted that he looks like a "lady killer" to her, implying he is handsome. Luna also expressed an attraction to Senku. His stone markings are two, symmetrical diagonal lines on top of his inner eyebrows. Pre-Stone World, he wore a typical school uniform with a lab coat over it. After waking up in the Stone World, he switched to wearing animal skin clothing in a rudimentary manner. After Yuzuriha's de-petrification, he gets these clothes patched up in a better manner. He has Albert Einstein's mass–energy equivalence formula (E = mc2) written in his own blood across the breast of his shirt. During Minami's photoshoot for his launching of the hot air balloon, Senku wore modern outfits fashioned by Yuzuriha. Senku is a straight-forward, confident and highly logical individual who can come off as arrogant. Even so, his borderline-overconfidence does not cloud his judgment, as he is often backed up by his superior and vast knowledge of science. Senku never belittles those who are less knowledgeable than him. Rather, he encourages and inspires everyone around him to do better. Because of his charisma and caring nature, people tend to gather around him, both allies and supporters alike. However, he can act over-the-top at times when he is excited over a creation or at the discovery of something new. Despite his usual appearance brimming with confidence and determination, Senku is not above berating himself, such as when Kohaku noticed the North Star being slightly off its location while he didn't assume so from the amount of time that has passed being petrified. Senku has a very logical mind, believing that there is nothing science cannot explain, even if it takes a long time for science to properly understand any one thing. Although he has a strong sense of justice, he often bends the rules, withholds information, and manipulates others to get what he wants, but if only for the better of his allies. He often acts as if he builds inventions and uses people for his own interest (such as glasses, and the automobile), but beneath his arrogance and manipulative nature lies a genuinely selfless and kind heart. This is proven time and time again, particularly when Senku mourns his adoptive father's death. During their decisive battle, Tsukasa notes that despite Senku's apparent cold rationale, his greatest weakness is his inability to abandon his friends, having witnessed his kindness firsthand with Yuzuriha taken hostage. Unlike Taiju, Senku seems averse to the idea of romance. He seemed disturbed when Kohaku worded her praise for him strangely, claiming she had "fallen for him." In addition, he immediately divorced Ruri, in the few seconds of their marriage. He was also completely unaffected by Amaryllis' attempts to charm him, much to her chagrin. He believes a brain filled with love is most illogical, but he does support his friends, such as Taiju's relationship with Yuzuriha, and Chrome's relationship with Ruri. Despite all this, Gen believes that one day, after all the conflict is over, he may consider the idea of romance. What Senku lacks in physical ability, he more than makes up for with his determination. He counted the time he was petrified to the last second for nearly 4 millennia, and willingly faced death by Tsukasa's hand because of his refusal to end his science and to protect Yuzuriha without being fazed. Senku also defeats Ibara with his quick thinking and help from Ryusui Nanami. Senku is simply someone who refuses to give up on a task no matter how arduous.
