The New Foe
Ryusui states that it's plausible Why-man would contact again, soon the latter does. Ukyo declares that its a synthetic voice, as Gen wonders how its possible in the Stone World while also wondering on the Why-man wanting to petrify them. Chrome wonders if Why-man is using Senku's voice from the latter petrified Ibara. This raises questions, as Kaseki wonders why the weapon was even on the island. Senku states they need someone who was on the island to know. Soyuz recognizes the symbol but does not know the history.
They soon revive an unknown person who is shown to have the symbol of the Petrification Weapon on his reattached arm. Once revived, the man is revealed to be a warrior named Matsukaze. Through him, they learn that other Petrification Weapons once fell from the sky centuries ago and he served under a man who resembled Ginro. The Kingdom of Science then determined that the Why-man is on the Moon. 
Return to Ishigami Village
In order to combat their foe, they decide they will have to build a space shuttle using materials from around the world.
They proceed to revive all those on the island, save the previous leader who is unable to be revived. They also learn from Matsukaze that their Petrification Weapon is the only one left after the destruction of the others. They celebrate their victory, as the island welcome Soyuz back home. That night, Senku and Kohaku share thoughts about the ordeal and that of Senku's father and his journey of thousand years ago.
They prepare for voyage, while leaving Soyuz to take leadership of the tribe while taking Kirisame and Matsukaze as his replacement. Soyuz reveals he memorized the Revival formula and will depetrify everyone still petrified. The Perseus departs the island after making it a part of the Kingdom of Science and leaving a radio tower there. Senku tells the others that he will need a crew consisting of him, Ryusui, and a powerful warrior. He declares they will return home to revive Tsukasa. 
Reviving the Strongest Primate
The Perseus returns to the Kingdom of Science, where they are greeted by their friends who cheer on the victory.
Senku reveals the Petrification Weapon is almost depleted of power but he will use its remaining power to petrify Tsukasa. The act works and Senku promptly revives him, successfully restoring Tsukasa to full health.
After sharing a moment with his sister, Tsukasa then questions Senku on the situation, as Matsukaze remarks on his forwardness, something the others aren't surprised on. Tsukasa is then shocked by Senku's plan to head for the moon and how they need a warrior. When Ginro remarked on Matsukaze's strength and states he may be more suitable than Tsukasa. Matsukaze observed that Tsukasa is a skilled fighter. Curious about the latter's skill, he challenges Tsukasa to a sparring match but is easily bested by his opponent and in awe at his defeat, he surrenders. After the topic shifts to Senku's scars, Gen rallies everyone into adorning war paint to recreate their scars as a sign of loyalty to Why-man's defeat. Tsukasa himself joins in on the act.
The New Voyage
Knowing that there will be many places in America, they decide to create new cities, starting in America and establishing Corn city. After setting off from Ishigami Village for America, it is revealed that Minami has been allowed to come aboard to document the journey. Suika has also been rewarded after her help during the last time by being allowed to come along. Whilst doing interviews with the rest of the crew Minami; she causes both Kinro and Kirisame to become embarrassed after asking what they think of each other, learning Matsukaze seeks revenge on Why-man, Tsukasa declaring he will defend them, Chrome and Kaseki discussing the ship's functions, and Ginro's fear of the journey.
During the voyage, Senku and Ryusui get into an argument over which route to take, with Ryusui optioning to take the long way round due to the crew's inexperience with sea travel. As a result, the two recreate poker with Gen siding with Ryusui and Kohaku with Senku. In the end, Senku wins the game and his course is chosen.
A party is held after the poker game, Ginro convinces Matsukaze to relay his story of how the Petrification Weapon got to Treasure Island, how his master died, and how he ultimately came to be petrified. He receives a cocktail from Francois, and passes out after one sip. He wakes up and participates in weapons training with the revived Hyoga who agrees to join on the condition that he be allowed to revive other fighters aboard the Perseus. His condition is accepted with the warriors training.
The Perseus then continues with the crew being amazed by the sights of the sea. Very soon, Homura reports that land is in sigh and they are pleasantly amazed to see them reach land.
Arrival in America
When the Perseus arrives in San Francisco, the crew of the Perseus yells that they have finally reached America. They are desperate to get back on solid ground and eat fresh meat. Ukyo remarks that the crew has had very little meat during the voyage. Tsukasa notes that the fighters of the crew have been training hard and crave animal protein, as Kirisame is seen behaving relieved. Homura draws the crew's attention to the petrified people lodged halfway into the cliffs nearby. Senku stews over this, as Gen sadly discusses his hope that the lie he fabricated for the fake Lillian had been true: that America had recovered from the petrification, or beaten it altogether. Taiju and Senku tell the crew that they can revive the people no matter what.
The warrior team follows the exploration crew in the motorboat and mobile lab. Soon alligators attack, though the other warriors defeat them and use the Alligator meat to restock on supplies. The crew are exceptionally pleased with the hamburgers that François made from them. Tsukasa then shows one of the Alligators had swallowed an ear of corn and Senku realized gathering corn might be in grasp.
Attack from the Shadows
After setting up camp, the Kingdom of Science discuss things and Senku notes there must be a corn field nearby. Tsukasa then senses an ominous feeling, before he smells smoke, realizing it came from a gun. Hyoga remarks the new enemy did well in luring them to a trap, after noting on finding corn so easily.
Realizing the danger is imminent, Tsukasa alerts everyone to go inside the boat, as bullets rain down and everyone ducks for cover. As the bullets are fired, Ukyo notes that it came from a machine gun. After the gun stops shooting, Ryusui has the group enter the boats before fleeing the scene. Once they leave, the unidentified shooter notes on their escape, while they are revealed to have petrification scars, signifying they were revived. Once at a safe distance, the Kingdom of Science note on the events, as Ukyo brings up the plausible cause of someone reviving on their own like Senku and Ryusui notes they grew the corn field. Senku states they should be grateful because the person did the grunt work for them. However, he notes if the person is a scientist then that person is finished because he won't lose in his strongest field.
Taking the boats down a river, Senku's group discusses a new threat posed by the culprit behind the machine-gun attack. Senku and the group deduce that the attacker has scientific tools more advanced than the groups.
In the midst of the discussion, an engine sound coming from above and they discovered an airplane flying over them. After a brief argument of what should be done, they increase their descending speed whilst being assaulted by another machine gunfire. Ginro panics as Matsukaze is grazed and Yo desperately tries to shoot the plane above with Hyoga telling him it's pointless and a waste of ammo. Soon after, Senku quickly combines water and calcium carbide to form acetylene gas, which he then gives to Kirisame who throws it at the plane, knocking the engine down and making the plane crash, much to the pilot's amusement. After they come out of the crashed plane, the mysterious attacker explains to the person on the other end of their communication device how the attack was carried out. They conclude that the opposing group has an experienced scientist just like the pilot.
Once things have calmed down, a scared Ginro suggests running away as their foes might bring reinforcements now that their attack has failed, while Senku and Ryusui gleefully disagree and suggest they take the crashed plane before reinforcements arrive. As they drag the stolen plane down the river, Senku and Ryusui celebrate, having captured a part of their enemy's firepower. 
The Kingdom of Science note the enemy would perform a tactical retreat, as Senku announced plans to track the enemy. Gen is worried on who will be selected for this endeavor, before surely enough he is picked along with Kohaku and Chrome, to his dismay. Gen bemoans this, while comrades are eager for exploration of the land before Gen realized the enemy is drawing his group in and feels insulted at being underestimated. A now driven Gen he tells Kohaku and Chrome to stand back while he goes off, but not before leaving a trail behind. Gen is found in forest by the enemy and quickly surrendered when a weapon was pointed at him. The enemy proceeded to check Gen but found no weapons and realizes he is not one of the warriors he saw from before. The soldier questions who Gen before Gen reveals he is magician and has Gen follow him. During the trip, the soldier is revealed to have been following his group, since the Alligator hunt and was planning to snuff out his allies sooner but now wants to interrogate Gen for what his colony is. Leading Gen to the American base, the American fortress is fully development and finds the corn field and landing strip. Gen is led to a factory, where he is put onto something and meets the American scientist Dr. Xeno who introduced the soldier as Stanley Snyder before intently questioning Gen on who he is and where he came from. Gen gives his name and some of his history, though withholds his status as a mentalist. As Xeno is fascinated to hear that the man comes from Japan, Gen realizes what he is placed into resembles a polygraph test and decides to use his mentalist tactics. Gen describes his leader's behavior, Xeno makes a point that the stranger may either be honest to a fault or a very good liar. He doesn't mind however, saying that he is fond of both types and Stanley resolves to eliminate his colony's scientist, to Gen's worry. At the end, Xeno inquires on the leader scientist's name, knowing Senku would be easily eliminated Gen thinks of someone stronger and replies with "Dr. Taiju".
Conflict of Interests
The Perseus then gets another call, it is Dr. Xeno who has located the frequency of the group's communication. Xeno requests to speak with his equal, wanting to negotiate with "Dr. Taiju", something that leaves the crew confused. It doesn't take long for Senku to realize this was because of Gen and Taiju dresses up for the part. Despite the struggling call, Taiju talks with Xeno while being walkthrough by Senku on what to say and successfully fools Xeno, to the amazement of his allies.
Xeno states that his side has a clear technological advantage, revealing he has a factory that can produce mass amounts of ammunition. To everyone's shock, Xeno reveals that his side is lacking manpower because he has no means to depetrify the statues. For that, he makes them an offer to completely surrender and serve him. From these statements and a comment from Magma about not reviving an army, Ryusui realizes the enemy doesn’t have revival fluid. His suspicion is confirmed, as Xeno also mentions that only those who have been aware during all 3,700 years can be revived with nitric acid alone, before questioning Taiju how he revived the statues thereby unintentionally confirming to the group he has no idea about the revival fluid. Ryusui prevents Taiju from letting the enemy know this, as Senku informs him they will simply crush the group once they have the manpower to do so. Senku states that they could have Corn City running with the formula. With this, Taiju rejects Xeno's offer and Xeno promptly ends the call.
The group hear a noise and spot another plane, shocked the enemy had another one. Flying above the Perseus, Stanley has discovered the location of the crew's ship. The Perseus crew ask Senku on what they should do, as Senku states they'll battle the enemy in the sky with their new vessels. Senku announces to the crew that he and Kaseki are building a runway for the Perseus.
Knowing that the enemy will not negotiate with him, Dr. Xeno decides to eliminate Taiju. Co-currently, Senku and Tsukasa decide to send a small squad to capture Xeno in order to bring him down. The group consists of Tsukasa, Hyoga, Ukyo, and Suika. Both groups then sit out to carry out the mission.
In the forest, Stanley leads a squad consisting of a young woman name Luna into a purse suitors Carlos and was Max revealing that he has a purpose for them. As this happens, Tsukasa and his group are struggling to track Xeno. Meanwhile, Luna is tasked by Stanley to infiltrate the enemy and lure out the scientist for him to snipe him. Adopting the persona of a runaway from a tyrant, Luna is helped on the ship by Senku who takes up a charming manner. This proves to be a facade, as Senku is shown with having devious plans for the obvious spy.
Now that Luna is on the Perseus, she started to work out who the Scientist is before noting to herself on what type of man he is, believing that he might be an intelligent hard working man with conviction to match, her exact preference. As she makes her way through to the ship, the crew are skeptical of her. After eliminating a few candidates out, Luna continues to search until Yuzuriha casually says Taiju's name and the latter reveals himself. Although flabbergasted to find Taiju, who is not what she expected of a head scientist. However, she begins to ponder how to lure him for Stanley to eliminate. As she does, she realizes that she didn't feel attracted to him but instead felt attracted to Senku whose nature surprises her. The crew believe he will gradually charm her but are shocked when he makes no qualms of hiding his intentions or intelligence. With help from Ryusui and Francois, Senku uses science to make soft serve ice cream to tempt her. The crew all enjoy the treat, while Luna is surprised and states if Xeno was present he would say the word Elegant. Senku is particularly shocked, asking Luna if Xeno was a NASA scientist and the surprised girl confirms it. The others note on Senku's familiarity, before Ryusui ask who Xeno is to him and Senku reveals that Xeno was his science mentor. 
Story of Scientists
One day at NASA, the scientists receive a strange email from a young Senku Ishigami. While most were hesitant to respond, due to his intentions, Xeno replied and tells Senku what he would need to conduct his experiment. Xeno and Senku continued to correspond about science for a while. Soon Senku is inspired to start inventing. At ten years old, he visited his father at NASA to obtain his credit card to finance his inventions.
Sometime later, Xeno was asked on what he would do if the world was sent back to the Stone Age and he responded that he would serve as a dictator over the less sophisticated. In response, Byakuya laughed at this in good fun. Five years later, Byakuya announced his son Senku would visit and Xeno is shocked to learn the boy he taught was the son of his colleague and will be at NASA. Xeno found Senku while he admired a monument of a ship and approached by silently standing next to him, both obviously knowing each other. When an excited Byakuya greets his son and ask why he seems spaced out, Xeno is seen walking away.
Xeno began investigating the petrified birds and wondered about the cause. At the same time, Senku was experimenting as well. The day of the Petrification, Xeno met with the military unit led by Stanley Snyder at the NASA headquarters for an expo while Senku was conducting his experiments of gasoline. Xeno soon explained his findings before a mysterious light appeared. Xeno along with the rest of the world was petrified for thousands of years. It is shown that most of the future colony maintained consciousness in that time, due to Stanley's orders and their own determination. On April 4, 5739, Xeno was freed while coincidentally Senku was freed of petrification.
After being freed, Xeno and new group of followers decide they must survive in the new primitive world. Using the platinum from Carlos' ring, constructed the fortress in San Francisco. As this occurred, Senku and Taiju began experimenting to create the Revival Fluid. After the story, the crew are amazed by the fact that both scientist revive on the same day but oppose each other. Meanwhile, Luna ponders Senku's past association with Xeno means, Luna notes on her possible attraction to Senku and attempts to eavesdrop on his conversation with the others. However, Taiju's yelling makes her recall her goal of having him assassinated. Senku then tells the group that he has a plan for Xeno. He reveals the Petrification Weapon, stating its technology will fascinate Xeno. Soon Luna tries to signal Stanley but after hesitating for a while she is unable to because of the kindness the crew showed her. Luna then decides to notify her comrades of Senku having a connection to Xeno. Carlos and Max send the info to Xeno while Stanley prepares the shot. However, Xeno stops him, revealing the true scientist.
The crew is thrown into disarray after Ryusui revealed a sniper, while Stanley is annoyed by it making harder to find Senku. Xeno describes Luna is worried that the plan fell through before looking into the direction of Stanley. This enables Stanley to identify Senku when he looks to Stanley's direction. Thinking quick, Senku ducks for cover before Stanley confers with Xeno if he really wanted his pupil dead. Xeno confirms after realizing their methods differs. Stanley takes the shot but Senku creates a bullet proof vest. 
After Senku is wounded from the aftershock of the shot, Luna wonders what she has to do now at the mission have been a success. Luna remarks on a quick thinking of Senku, after he created a bullet proof vest. Luna recalls her time in the medical class and remembers the basics, easily diagnosing Senku. The crew believe that she might be a doctor but Luna states that’s not the case though Taiju begs her to help his friend and she agrees. 
Luna remained on the Perseus where she tended to the wounds of Senku.
Luna continues her work and noted to herself that her impression on Senku was accurate because the scientist was confirmed to be him. After he wakes up, he tells her that he needs to get a transfusion to heal him though some of his methods worry her, she agrees. Luna then states that there is only one condition he has to agree to: being her boyfriend. Chrome's group are able to make a tunnel before they receive a message in Morse code. It is Luna who wanted to tell Carlos of the good news, much to his dismay. Kohaku and the others can already guess Senku's motives while Carlos decides to help the Kingdom of Science by drawing a layout of the castle. Sometime at the bar, Luna is talking to François about her recent relationship and she becomes dismayed when she hears that Senku was briefly married and used it to further his goals. They also speculate that he's doing the same thing with his relationship with her. Yo soon tells them that the enemy is approaching before they all ready for battle. 
Clash of Science
Using their new plane, Senku and Ryusui engage Stanley in an aerial battle, while.
As the the aerial battle continues, Senku has come up with a counterattack against Stanley. Meanwhile, it is revealed Xeno has created a submarine to take the Perseus. The crew come under attack by the warriors of Stanley's unit, who proceed to capture most of the crew. However, Matsukaze, Moz, and Ginro remain free after realizing danger was approaching. They soon move out to face the enemy. 
Moz and Matsukaze arrive at the deck, overpowering most of the warriors with their respective skill. Soon the aerial battle ends after Senku uses the same method to bring down the enemy ship, he used before and the engine stalls. However, Senku and Ryusui's plane is also brought down. Ryusui tells Stanley to come out of the wreckage but it is not Stanley but rather a member of squad.
Back to the Perseus, the enemy announces it is time for their leader to appear. Stanley then makes his entrance, to reach the ship. Stanley uses his pistol and easily overpowers Moz and Matsukaze. Stanley reports the enemy has been defeated. At the castle, Xeno relishes in his victory. However, he gets a transmission from Senku to tell him that he was not the only one who sent his knight. Shocked, Xeno is then confronted by Tsukasa who holds him at swordpoint. 
Soon the rest of the group arrive, Xeno is fascinated they reached the area by tunneling. He takes note of Chrome's amazement with his technology before he is captured. Taking a captive Xeno to the tunnel, Chrome reveals that he anticipated the enemies and brought a bomb to close the tunnel. Chrome reluctantly stays behind to do so but a cave-in occurs. While stuck with Chrome, Xeno offers him the position of commander if he joins with him, since his allies are likely defeated and if they join together they can rule the stone world. Chrome refuses the tempting offer well stating because of Senku, he has learned not to use Science to control people. Chrome then contacts Senku to tell him that he was captured.
On the Perseus, Max helps Luna, Francois, and Kaseki escape to meet up with the others. Afterwards, Senku and Ryusui arrive at the American Colony Castle to meet up with Chrome's group. His appearance and survival leave Xeno shocked and amazed that his former pupil survived. Senku and Xeno share some words with his former apprentice, before Xeno tells to him that he is already lost the battle because of Stanley commandeering the Perseus. Luna's group arrive to join Senku. Knowing the enemy will pursue them, the group steal one Xeno's spare boats. Afterwards the group realize there's someone in the American colony who would most likely not want to see blood shed in contact Dr. Brody. Brody is uninterested in the truce until Senku makes him an offer. To his allies' great shock, Senku reveals the ingredients to the revival formula and how they could get it from corn. Xeno and Brody are speechless by Senku handing over such info.
