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 friends with Taiju Oki and Yuzuriha Ogawa. He was depetrified half a year before Taiju was, and eventually created the Revival Fluid with Taiju's help.[17] In the Stone World, Senku's goal is to rebuild civilization and establish a Kingdom of Science. As the first-prize champion in the Grand Bout, Senku currently holds the title of Village Chief in Ishigami Village,[18] where he is widely regarded as a legend thanks to the late Byakuya's influence in the founding of Ishigami Village.[19] Senku is also the leader of the Kingdom of Science, providing the ideas and initiative for their large-scale plans. Later, he is given another title as one of the Five Wise Commanders, as he was one of the five people on the boat who first heard Why-man's message.[20]
