Kingdom of Science and Tsukasa Empire When Tsukasa was revived and had some differences with Senku, two factions arose. The was made by Senku to recreate the scientific achievements in the world. The or Empire of Might was made so the strong could rule. When Hyoga was defeated and Tsukasa entered cryosleep, the remnants of the Tsukasa Empire merged with the Kingdom of Science which later gained new members from those who were freed from their petrification. ; : :Hyoga is a tall and fairly built spear-armed man who is strong enough to take on 10 attackers. He is revived by Tsukasa during the "Vs. Hyoga" arc. Hyoga and some Tsukasa Empire fighters took on the Ishigami Village's finest until it was discovered that Gen rigged their weapons. Hyoga himself is an elitist who believes in
social Darwinism. After Mirai's revival, he betrays Tsukasa causing an unlikely team-up between Senku and Tsukasa to defeat him. The imprisoned Hyoga had to accompany Senku who needed some additional muscle. Later, in the "Treasure Island" arc, Senku revives Hyoga to fight against Moz, only for them to both get petrified by Ibara, causing him to be a statue again. In the "South America" arc, Hyoga is reformed and officially joins the Power Team. ; : :Homura is a member of the Tsukasa Empire who was a
gymnast prior to the petrification and is the right-hand to Hyoga. Homura was released from her petrification and has an allegiance to Hyoga. Homura assisted Hyoga in the first attack on Ishigami Village where she snuck into the village and set fire to some of the huts. Her gymnastics prowess means her speed and agility are more than a match to Kohaku's. During the "Communications" arc, she did some surveillance on Ishigami Village. When Homura tried to sabotage the radio tower, Magma and Kinro cut the tree enabling Kohaku to catch her. Homura did manage to cave-in the
Miracle water obscure the revival fluid. During the "New America" arc, Homura had to accompany Senku who needed some additional muscle. ; : :Minami was a journalist prior to petrification who knew famous people. After being released from her petrification, Minami serves Tsukasa where she wears a leather dress and is always barefoot. She is heavily enamored with Tsukasa. Both of them agree that the world before the petrification was awful. When Hyoga was defeated and Tsukasa entered cryosleep, Minami was among those who joined the Kingdom of Science where she joined their Intelligence Team. During the "Age of Exploration" arc, Minami and Gen bargain for the stone formula so that they can reawaken Francois to recreate the camera. She wastes no time in chronicling
Perseus voyage. ; : :Ukyo Saionji is an SDF Navy
sailor and submarine sonar operator who was released from petrification by Tsukasa. He is an expert in different languages and has super-sensitive hearing. When he worked with Tsukasa, Ukyo became an expert archer and one of Tsukasa's scouts. During the "Communications" arc, Ukyo attacked Chrome, Gen, and Magma while setting up telephone poles which ended with him capturing Chrome. When Senku and Gen made contact with him, Ukyo agreed to their terms in exchange for a "no death" rule due to Tsukasa shattering petrified humans and suspecting that Hyoga had sacrificed their fellow warriors to the sulfur gas. Following Hyoga's defeat and Tsukasa entering cryosleep, Ukyo is among those who join the Kingdom of Science where he becomes one of the Five Wise Generals. ; / : :Niki is a devoted fan of Lilian Weinberg who was revived by Tsukasa. She is a tall athletic woman and has a good deal in handling others. When Senku states he has the final surviving copy of Lillian's song, Niki quickly changes sides. She is also keen on linguistics. Niki is among those who join the Kingdom of Science where she becomes part of the Power Team. She is usually the one who disciplines Magma and Yō in line if they do something short-sighted. ; : :Yō is a former police officer who was revived by Tsukasa and one of the Empire of Might members who quickly joined Senku's new Kingdom of Science as a member of the Power Team where he occasionally comes into conflict with Magma. His most noticeable feature is a massive piece of stone covering his right eye which he later removed and gave it one of Tsukasa's men when faking his death upon Chrome's escape (though the stone eyepatch reappeared on him in later appearances). Then he worked with Yuzuriha to rebuild the petrified humans that Tsukasa shattered. As a former police officer, he can use both
tonfa and an expert marksman, thus being granted by Senku a gun. ; : :Francois is the butler and chef of Ryusui who is unsure what gender Francois is. During the "Age of Exploration" arc, Francois is revived by Senku and Ryusui to work for them after suspecting Minami was hiding some leftover revival fluid. Francois sought to cook and save provisions for the sailing crew of
Perseus. Francois did the first task in culinaring bread. ; : :Mirai is the younger sister of Tsukasa. Prior to the Petrification, she was brain-dead following a car accident. During the "Communications" arc, Mirai was restored by Senku and the formula also healed Mirai. She was sad to see her brother go into cryosleep. During the "New America" arc, Mirai found that everybody lost their scars and used the Petrification Device to heal Tsukasa. ; : :The prodigal oldest son of Nanami Conglomerate's owner was revived by his younger brother in the "Europe" arc. Despite being an expert on video game IT who can crack
algorithm codes, he ran away from his family company and fled to a university in India due to seeing Ryusui being too annoying to him before the day of the first full-scale worldwide petrification. In contrast to Ryusui, Sai is a timid and more self-conscious person. He brushes off his talent for quick mental math as nothing special. He became prone to panicking when reuniting with his brother and a world without computers. While bonding with Ryusui in a game of chess, Sai is brought to tears when the computer is finally re-crafted and agrees to tutor the two rookie scientists, Chrome and Suika, to build a two-way rocket plan.
Ishigami Village inhabitants The inhabitants of are descended from the surviving astronauts of the
International Space Station who were off-world at the time when the petrification light caused all humans to be petrified. It became the headquarters of the Kingdom of Science. A
village chief is chosen from whoever makes it to the final part of the Grand Bout games and wins. When a person becomes the village chief, that person is entitled to a lot of resources from Ishigami Village.

During the "Vs. Hyoga" arc, Kokuyo assisted in defending Ishigami Village from the Empire of Might fighters led by Hyoga. ; : :One of Ishigami Village's
guardsmen, a stern young man with a strong commitment to the rules eventually joined Senku's group as part of the Power Team.

In addition, he also became part of the Power Team during the merging of the Kingdom of Science and the Tsukasa Empire. He loved his little brother, when he learned in both sadness and anger that Ibara had his unwitting servant Kirisame petrified Ginro and Kohaku. ; : :Kinro's younger brother and fellow guardsman is a frivolous young man with a tendency to panic and an overriding sense of self-interest. He rallied all his courage to assist Senku and Chrome in sampling a dose of , the embodiment of the
sulfuric acid required to make antibiotics for Ruri. Ginro becomes part of the Power Team. ; : :Kohaku's older sister and Ishigami Village's
high priestess tasked with preserving the for posterity. She suffers from a debilitating illness that will likely kill her before adulthood and finding a cure becomes the first goal of Senku's "Kingdom of Science." Senku's team spent most of the first arc obtaining magnets and sulfuric acid to make an antibiotic to cure Ruri. Ruri and Senku had a short-lived marriage when he grabbed the alcohol needed for medicine. Once she is cured of what turned out to be
pneumonia, she reveals to everyone including Senku that the latter is a legend amongst the village's community, all comes from the influences from one of the villagers' ancestors, who happens to be Senku's late adoptive father, Byakuya. ; : :An elderly but ripped
artisan from Ishigami Village, he becomes a staunch ally and eventually a close friend of Senku and Chrome because their quest for science resonates with his passion for crafting. While having designed and built much of Ishigami Village, Kaseki used his artisan abilities to create Kohaku's shield and items from Senku's diagrams with little practice like glass, engines, and vacuum tubes. Kaseki is made unofficially to join the Craftsmanship and Development Team. ; : :An inhabitant of Ishigami Village who is a stickler for rules. During the "Village Games" arc, Jasper served as a match referee for the Grand Bout. He serves as a guard for the village's priestess. ; : :An inhabitant of Ishigami Village.

Her worries diminished once Senku's team started cultivating wheat. ; : :An inhabitant of Ishigami Village who is the most aggressive of its inhabitants and helps to defend it from attacks, having intended to take over the village before accepting Senku as their leader. As a member of the Power Team following the merging of the Kingdom of Science and the Tsukasa Empire, he takes a liking to Taiju due to his unlimited stamina as seen when Magma watched him tend to the fields where he did not tire out. Magma later learns he is talented in the Mathlympics. ; : :An inhabitant of Ishigami Village with
dwarfism who idolizes Magma and does his dirty work. ; : :A bald-headed inhabitant of Ishigami Village with great photographic memory and a member of the Power Team. He is often shown shirtless, has an X-scar on top of his head, and is always barefoot. As a baby, Soyuz was originally from an island that Senku named "Treasure Island" before he was cast off, presumably sometime after surviving a hostile takeover caused by Ibara. Soyuz is the son of the leader of his birth kingdom whom Ibara petrified.

Petrification Kingdom The is a kingdom that is located on Treasure Island. Its inhabitants are the descendants of the International Space Station crew. Soyuz came from this island as he was the son of the unnamed leader. ; : :Ibara is the sociopathic, selfish, perverted and paranoid Minister of the Petrification Kingdom until he usurped the unnamed ruler who was Soyuz's father and used the Petrification Device to petrify him and punish eyewitnesses or outsiders that would put his treachery at risk. When Senku arrived on the island, Ibara became determined to kill or petrify him and his friends due to being threatened by their advancements and being outside his control and authority, with Senku and Ryusui getting into a tug-of-war with Ibara. Thanks to a trick that Ryusui planned out, Senku used the voice com to frighten Ibara and use the Petrification Device on him. This enabled Soyuz to become the new ruler of the Petrification Kingdom. Ibara is the only villain Senku is not willing to pardon, leaving him left to be petrified by those he deceived and oppressed. ; : :Amaryllis is the most beautiful inhabitant of the Petrification Kingdom. She is skilled in gathering ingredients for food and cosmetics. Five years ago, she and some kids tried to leave the island but were stopped by Moz and Kirisame. Amaryllis sides with Senku regarding his plans to overthrow Ibara only for Ibara to use the Petrification Device on everyone. Upon being restored after Senku defeated Ibara, Amaryllis assists Soyuz in restoring the people of the Petrification Kingdom. ; : :Kirisame is a female chief of the Petrification Kingdom who is one of the two strongest warriors. In her first appearance, she was responsible for the petrification of the
Perseus crew. Kirisame is the first to suspect something off about Ibara's intentions of petrifying the whole island and is outraged when the truth comes to light. After Senku defeated Ibara, Kirisame was among those who restored and recognized Soyuz as Treasure Island's new ruler. Kirisame later joins up with the Kingdom of Science. ; : :Matsukaze is a samurai of the Petrification Kingdom who petrified himself centuries ago in the event in which many Petrification Weapons fell from the sky. At some point, his petrified body ended up in the sea and was collected by Taiju. Matsukaze was left petrified from missing an arm. When his arm was salvaged and reattached, Matsukaze is restored and saw that Ginro resembled his late master. He joins the Kingdom of Science where he becomes Ginro's bodyguard. ; : :Oarashi is a muscular man of the Petrification Kingdom who sports a
jackal headdress. While he is strong enough to throw Magma and Kinro, he is no match for Taiju. ; : :Moz is an inhabitant of the Petrification Kingdom and is one of the two strongest warriors. Because of this, he believed himself to be naturally talented at fighting, so he preferred to slack around rather than hone his skills. He has a soft side for girls he finds beautiful or strong like Amaryllis and Kohaku. Moz briefly comes to terms with Senku's allies. Following Ibara's defeat, Moz is restored by Senku at Hyoga's behest and he joins up with the Kingdom of Science.
