The Medusa is the mysterious technological device shaped like an amulet or metallic sphere that has the power to turn living beings to stone. It is the central object and ultimate weapon in the Treasure Island arc. It works as follows: Voice Activation: For it to work, the user must hold the device and say aloud a distance and time in any language (for example: "3 meters, 1 second" ). It responds directly to the clarity and precision of the command given. The Petrification Flash: Upon receiving the command, the device emits a flash of green light that instantly expands, forming a perfect dome up to the indicated distance, instantly petrifying any human or swallow it touches. Energy Consumption: It operates on tiny glass capsules that act as batteries. Each time it is used, the energy is depleted.
On Treasure Island, Medusa is under the control of Chancellor Ibara, who uses her through his most loyal warrior, Kirisame, to keep all the inhabitants under absolute control and in fear.

.
📻 The Stone Wars
Tsukasa's Empire launches its military offensive against the village. To win without bloodshed, the Kingdom of Science invents cell phones (secretly transported across the Great River and through the mountains) to communicate with Taiju and Yuzuriha. Using psychological propaganda created by Gen and the firepower of a construction paper tank, they assault the Cave of Miracles. The battle ends when Senku vows to cryogenically freeze Tsukasa after he is betrayed by Hyoga. With Hyoga and Homura defeated, both factions merge under the banner of progress.
⚓ The Age of Exploration and the Sailing
To uncover the origin of the global green flash, the Kingdom of Science decides to build a massive vessel: the Perseus. To pilot it, they resurrect the eccentric and ambitious shipping magnate, Ryusui Nanami, who brings with him his impeccable butler, Francois. They also recruit Ukyo Saionji as the team's sonar operator, thanks to his perfect pitch. After gathering raw materials using geographical maps and conducting tests on the high seas, the crew sets sail for the open ocean.
🏝️ Arrival at Treasure Island (The Landing)
Following the clues left by the village founders and accompanied by Soyuz, the ship finally spots the silhouette of the mysterious and inhospitable Treasure Island. The Perseus drops anchor near the shore. At this very moment, as the first scientific exploration and military reconnaissance teams carefully disembark onto the white sand beach, an intense atmosphere of mystery and danger surrounds them: the Kingdom of Science has just set foot on territory controlled from the shadows by Chancellor Ibara.

⏳ The Great Petrification and the Awakening (Year 3700)

All of humanity is instantly turned to stone by a mysterious green flash. After 3,700 years of complete isolation and global erosion, Senku Ishigami awakens in a world where modern civilization has been completely reclaimed by nature. Months later, his friend Taiju Oki also frees himself from the stone. Together, they discover the formula for the Revival Fluid using nitric acid from the Miracle Zone . ### ⚔️ Clash of Ideologies Pursued by a pack of lions, they are forced to revive Tsukasa Shishiou , the strongest high school student. Although he saves them, Tsukasa reveals an extremist philosophy: destroying statues of adults to create a pure, natural world. Senku, determined to save all of humanity through science, clashes head-on with him. To save Yuzuriha , Senku fakes his death at Tsukasa's hands and temporarily separates from his friends, who remain in Tsukasa's Empire acting as undercover spies. ### 🔬 The Birth of the Kingdom of Science Senku travels outside and discovers Ishigami Village , a settlement of primitive humans. There he meets the warrior Kohaku , the "sorcerer" Chrome , the young Suika , and the master craftsman Kaseki . With their help, he begins to recreate technology from scratch: iron smelting, glassblowing, electricity, and a sulfa-drug to cure the priestess Ruri . During this process, the mentalist Gen Asagiri is sent by Tsukasa to spy on them, but decides to defect and join Senku in exchange for a scientifically recreated Coca-Cola. After winning the village tournament, Senku is appointed the new chief.

• *Tsukasa's Empire: A fortified camp located in a mountainous and forested area of ​​the continent. It consists of rustic huts built among trees and caves, designed to house dozens of revived, strong young people who live by hunting and gathering, rejecting technology.

Carlos Barrios: One of Luna's protectors and allies in the American group. He is a strong young man, devoted to Luna's safety, and stands out for his driving and land transportation skills in the new world. Max Adams: *Luna's other close protector on the American side.

🇺🇸 The American Faction (Rival Scientists and Military)

🚢 Additional Members of the Kingdom of Science

• *Ginro: The cowardly but lucky guard. In this arc, he travels on the ship and infiltrates the palace harem disguised as a woman alongside Amaryllis. Although he always tries to flee from danger, he ends up being a key player and is the reason Matsukaze joins the party, as he mistakes him for his former master. Kinro: Ginro's older brother and the village's serious guard. He stands out for his strict sense of duty and his spear skills on the front lines. Although the ship's mass petrification takes him out of commission at the beginning, his strength is vital once he is revived for the final battle. ### 👑 Key Inhabitant of Treasure Island Matsukaze: A samurai from centuries ago who was petrified beneath the sea. Upon being revived by the Kingdom of Science, he immediately joins them because he sees in Ginro the spitting image of his deceased former lord.
