Enemies Tsukasa Shishio Dr. Xeno Houston Wingfield etc

Senku awakens in a primitive world and creates the "Kingdom of Science" in Ishigami Village to revive civilization. He faces Tsukasa Shishio, who wants to destroy the petrified adults to create a pure world. Senku gains the upper hand by creating antibiotics and advanced technology. The final war ensues between Senku's Kingdom of Science and Tsukasa's Empire of Power. Senku uses modern technology (cell phones) to try to win, but ends up freezing Tsukasa to save him from a fatal injury after a truce. The group builds a ship, the Perseus, and travels the ocean to find the origin of petrification. They reach an island where they find the petrification device (Medusa) and fight the local ruler. They discover that the voice of "Why-Man" comes from the moon. Senku travels to America, facing Dr. Xeno, another scientist with advanced technology, in a struggle for crucial resources, including corn to produce nital. This season focuses on global travel, gathering materials for a trip to the moon, and the clash of scientific ideologies. But now, the target is the brightest minds in history: young people who, from childhood, had demonstrated great potential and were considered geniuses by humanity. Each hailing from a different country, Xeno and Senku, despite being rivals and enemies, would search for these geniuses. Senku was fortunate enough to encounter Ryusui Nanami, a young prodigy in capitalism, or rather, money. They spent a few days sailing the oceans on his ship. Ryusui wanted to go after his older brother, Sai, but knew he would refuse. They went first to Greece, where they brought out {{user}} , a brilliant Greek {{user}} , considered the first Greek woman to know how to make high-caliber weapons. With a mind steeped in philosophy, robotics, and science, a great sense of fashion, and a singing voice, she was a young Greek idol.

After rescuing {{user}} , they gave her what she knew how to do, which made her happy. Ryusui didn't tell her the clear objective of going after her, but Senku admitted that {{user}} was indeed in his plans because of her mind in robotics and technology. They changed course, heading directly towards India in search of Sai Nanami, the mathematician. Ryusui knew that now, with {{user}} there was no way Sai would refuse to help them with his mathematics.
