| Ryusui and Senku argue over which route to take to America. Ryusui desires to use the easier rhumb line that'll take 70 days, while Senku desires to take the more dangerous Great Circle Route that'll take 40 days. Senku wants to arrive in America in time to harvest corn to make revival fluid, knowing if they arrive in winter, they'd have to wait another year. To settle the dispute, Senku and Ryusui decide to play a game of poker where the winner will decide which route to take. Gen joins Ryusui's side, filling Senku with suspicion that they'll cheat, causing Kohaku to join Senku's side and use her sight to keep an eye on Gen. While Kohaku catches Gen numerous times, she and Senku become distracted for a split second, allowing Gen to change Ryusui's hand. Senku counters this and wins with a royal straight flush due to marking his cards with urushiol, which he is allergic to. To improve conditions for the crew, Ryusui sets up a casino so that everyone can join in on the fun while Senku creates beer as a last component for the morale boost. |||||||

Matsukaze shares his story about his late master to a drunken Ginro. Senku revives Hyoga who agrees to train Matsukaze in modern fighting techniques at Tsukasa's request on the condition that he have the right to revive two people, and as a result, Moz and Homura are revived by Senku and reluctantly join the crew. Inspired by the story of the Vikings who sailed across the sea all the way to America, Chrome creates a sunstone with a piece of calcite that they can use to pinpoint the location of the sun in any type of weather condition. After days of sailing across the Pacific Ocean, the science crew finally arrives in America. |||||||

| The science crew drops anchor in the San Francisco Bay. To find their corn, Ryusui splits the crew into 2 teams, one to gather resources on the ship and the other to find corn nearby. Tsukasa and the other fighters are assigned to escort the corn scouting and protect them from dangerous wildlife. While traveling up the Sacramento River, the team is suddenly ambushed by a large horde of crocodiles, but are easily disposed of by the battle team who provide the group with fresh meat for burgers. After finding corn in the croc's stomach, the group continue their journey upstream where Kohaku discovers more corn floating down the river, which fills Senku with suspicion. After contacting the team on the boat to look for corn in the Bay, Senku gathers a horde of bugs with a light trap and finds moths that eat corn, indicating that there is a large supply of corn nearby. However, Tsukasa senses a hostile presence and realizes that they've been lured into a trap as an unknown assailant starts attacking them with a machine gun, causing the group to flee. Ukyo deduces that someone revived on their own just like Senku and created their own settlement with corn fields nearby. This leads Senku to realize that they are dealing with another scientist with hostile intentions, raising his determination. |||||||
| 61 | 4 | "Dr. X" | Kayona Yamada | Kurasumi Sunayama | Chie Nishizawa | January 30, 2025 (2025-1-30) |
| As the scouting team return to the ship, they are suddenly attacked by the unknown assailant who is flying a plane. Taking matters into his own hands, Senku creates an acetylene gas grenade and gives it to Kirisame to throw at the plane, disabling its engines in the process. Following that, the unknown assailant crashes nearby, but manages to escape. The scouting team finds the crashed plane, and Senku and Ryusui decide to commandeer it for themselves, thinking that it will give them a tactical advantage in their favor. While examining the plane, they discover corn kernels, indicating that the assailants are using a cornfield runway. Senku sends Gen, Chrome, and Kohaku to scout the area and find the cornfield. While following the assailants' footprints, Gen believes that the enemy is luring them into a trap, so he decides to continue on ahead and leaves flower petals for the others to follow. He is soon confronted by the unknown assailant named Stanley Snider who takes Gen to see his leader. Upon arrival, Gen meets Dr. Xeno, the leader of the American colony and one of the smartest scientists in the world. Xeno begins interrogating Gen for information, including the name of his scientist leader, but Gen, wanting to protect Senku, lies to him and says that Taiju is their leader. |||||||
| 62 | 5 | "Doctor vs. Doctor" | Chako Sato | Kazuto Kaneda | Daiki Koyama | February 6, 2025 (2025-2-6) |
| Chrome and Kohaku scout the enemy's base of operations from afar and realize Gen has infiltrated it. They contact the science crew to inform them of what they found, but Senku, not wanting to risk the enemy eavesdropping on their conversation, quickly ends the call. However, having found their radio frequency, they are contacted by Dr. Xeno who asks for Taiju's presence, believing he's their scientist. Using this deception to their advantage, Taiju calls out Xeno for putting everyone in danger with machine guns, but Xeno reveals that he had a Haber-Bosch plant built to mass produce limitless gunpowder. When asked for information on revival fluid, Taiju refuses to tell Xeno their secret, even at the risk of war, causing Xeno to end the call. They soon hear another plane flying nearby, flown by Stanley, indicating that Xeno knows their location. Knowing that they won't risk flying low following the river chase, Senku plans to turn the Perseus into an aircraft carrier, and that they deploy the plane that they commandeered. Simultaneously, the science crew form a plan to take control of the factory and their cornfield by deducing Chrome and Kohaku's location from the timing of their radio signal with the understanding that Xeno's base is nearby. At the suggestion of Hyoga, a battle team consisting of himself, Tsukasa, Ukyo, and Suika are deployed into the field in order to find Chrome and Kohaku and capture Xeno as well. |||||||
| 63 | 6 | "Science Is Elegant" | Osamu Nabeshima [ja] | Kurasumi Sunayama | Osamu Nabeshima | February 13, 2025 (2025-2-13) |
| As part of Xeno's plan to eliminate the Kingdom of Science's leader, Stanley sends a young woman named Luna to infiltrate the science crew and find Taiju so that he can kill him once she lures him out in the open. Ryusui becomes suspicious of her, believing that she's a spy. Senku on the other hand secretly plans to extract as much information from Luna as possible about Xeno and his crew, that way, he’ll transmit the encrypted message to Tsukasa's special squad. Luna begins searching for Taiju, until she eventually finds him, but before she can attempt to give Stanley the signal, Senku appears and begins to charm her in an attempt to extract information from her about Xeno. He is suddenly interrupted by Ryusui and Francois as the former puts in a request to give her something desirable. Senku and Francois end up recreating ice cream for her to enjoy, much to her delight. In a surprising turn of events, Senku begins to realize who Dr. Xeno truly is and reveals that he is a former NASA scientist, as well as his old science mentor from his childhood who helped kickstart his passion of building advanced rockets for starters. |||||||
| 64 | 7 | "The Two Scientists" Transliteration: "Futari no Kagaku-sha" (Japanese: 二人の科学者) | Shunji Yoshida | Kazuto Kaneda | Satoshi Shimizu | February 20, 2025 (2025-2-20) |
| As Senku realizes who Dr. Xeno is, he flashes back to when he was a child still attempting to build his first rocket with Taiju. A failed attempt had him reach out to NASA for assistance, where most of the scientists agreed to not give a child that kind of information. However, a 20 year old Xeno responds with instructions and materials he can use, allowing Senku to borrow his father Byakuya's government-supplied credit card to gather what he needs. At the same time, however, Xeno's own projects keep getting rejected at NASA, leaving him bitter. When approached with a hypothetical stone world scenario by Byakuya at NASA, Xeno says he would rule with an iron fist, destroying any who opposed him. On the eve of humanity's petrification, both Xeno and Senku analyze the petrified swallows, with Xeno realizing they're still alive and can maintain consciousness. As the petrification wave hits the planet, Xeno orders Stanley, Luna, and the others to remain conscious at all costs. Knowing they'd both need corn for their respective plans, Xeno and Senku strategize an eventual trip to California when they both suddenly break free of petrification. |||||||
| 65 | 8 | "Lock On" | Chako Sato | Kurasumi Sunayama | Satoshi Shimizu | February 27, 2025 (2025-2-27) |
| Xeno breaks free from petrification and locates a nearby cave, deducing his freedom came because of bat manure-filled nitric acid. Using this compound, he awakens Stanley and the rest of his team, relocates to northern California, and establishes his Haber-Bosch base in order to set himself up for world dominance. Back in the present, aboard the Perseus, Luna feels conflicted about pointing out Taiju to Stanley nearby for him to snipe, so she mouths the name "Senku" into the nearby trees for Stanley and his team to relay to Xeno. Ryusui witnesses this, raising his suspicions even more, and as Stanley's team contacts Xeno, the radio signals aboard the ship show signs of scrambling, indicating a sniping team is nearby. As Ryusui announces this warning, Stanley is able to deduce who Senku truly is due to Xeno realizing that Senku is the true scientist upon calculating his height from an archive of voice recordings. With limited time, Senku takes cover and quickly combines starch and water in a bag to make a viscous bulletproof vest. Even while hiding, Senku's position on the Perseus is calculated by Stanley, allowing him to fire, striking Senku as he holds his bag. |||||||
| 66 | 9 | "Light of Science" Transliteration: "Kagaku no Akari" (Japanese: 科学の灯) | Tomomi Ikeda | Kazuto Kaneda | Daiki Koyama | March 6, 2025 (2025-3-6) |
| While his bulletproof bag softened the blow, Senku is badly wounded from the sniper shot and is now bedridden. As a former med student from the old world, Luna offers to help treat Senku's wounds after Taiju begs her to do so. Meanwhile, Chrome and Kohaku continue to scout the American's base from afar as Tsukasa, Hyoga, Ukyo, and Suika arrive, having followed Gen's flower trail. In order to infiltrate their base undetected, Tsukasa and Hyoga suggest digging their way in from beneath the base using an invention Senku could create. However, the team soon receives a Uesugi cipher message informing them of what happened to Senku. To buy themselves time to build their machine, Ukyo shoots an arrow with the Medusa to Xeno's base for him to analyze, as well as intimidate him about the true nature of the device itself. In his base, Xeno plans for a new weapon to be ready in two weeks, while Chrome, remembering everything Senku taught him, begins his roadmap to create the tunneling drill. |||||||
| 67 | 10 | "Dirty Roads" Transliteration: "Tsuchi Mamire no Michi o" (Japanese: 土まみれの道を) | Kayona Yamada | Kurasumi Sunayama | Kayona Yamada | March 13, 2025 (2025-3-13) |
| In need of parts to construct the drill, Taiju drives the mobile lab with equipment to Chrome's team. Along the way, he picks up Carlos, one of Xeno's two spies keeping an eye on the Perseus, knowing they'd tail him if he didn't. With parts in hand, Chrome's team puts the drill together and successfully test it. On the ship, Senku continues to give instructions to convert the boat into an aircraft carrier, causing Luna to fall in love with him for his leadership through duress. She sends Chrome's team an encrypted message, claiming Senku as her boyfriend, which causes Carlos to align with the Kingdom of Science since he's always "Team Luna" and draws them a map of the layout of Xeno's base. Having been wearing the radio earring the whole time, Gen breaks the number code for his understanding while Xeno's team finishes their new weapon. As Stanley flies his plane toward the Perseus as a sign of war, Ryusui and a mending Senku board their commandeered plane and launch it into the sky from the carrier to begin the dogfight. |||||||
