With the petrification device in the Kingdom's hands, it's time to revive Tsukasa. But there's just one problem: the device is out of batteries.

To the moon! That's the plan, at least. Senku and the Kingdom of Science need to devise a means with which to go to the moon and deal with Why-Man. The first step is allying with the people of Treasure Island and enlisting their help with some new crafts.

Senku stands victorious. He then works on reviving the others and fixing their communications device, but while they are talking with Ruri they encounter a strong interference with the signal.

Much to Ibara's shock and dismay, Senku devised a plan and managed to escape petrification. Now the two enter into a head-to-head battle for control of the Medusa device.

Yo and the Kingdom of Science capture the petrification device, but Ibara isn't going down without a fight.

The Kingdom of Science members launch an attack on the islanders aboard the Perseus, but Moz isn't far behind and Senku and the others are forced to retreat inside the vessel. Ibara has them cornered, but Senku unleashes his Joker card.

The Kingdom of Science attacks and tries to execute their plan to steal the petrification device. Moz convinces Kirisame to use the device, but Ryusui's instincts tell him something is off about the situation.

Moz and the Kingdom of Science form a tenuous, temporary alliance against Ibara. How long it will last is a question they can't afford to concern themselves with just yet.

More of the Kingdom of Science is brought back from petrification, but they are discovered in the cave by Moz.

The team revives Kaseki to work on the drone. Meanwhile, Ginro is called to see the Master.

Kohaku is forced to destroy Ryusui's statue to prove that she isn't a spy.

Kohaku has located the treasure left behind by Byakuya and the others, but it's encased in concrete. Senku has to devise a plan to quietly get at the contents inside, so as to not alert the guards.

Amaryllis, Ginro and Kohaku are chosen to join the inner palace. The science team will need a way to communicate with them in secret, and, eventually, a way for them with the science team.

Suika and Ginro strive to rescue the mobile lab from the Perseus.

Amaryllis explains how she avoided being petrified and how she decided to sneak into the palace.

The Perseus arrives at the Treasure Island.

The ship Perseus is completed, then the Perseus sets sail to the Treasure Island with a select Ishigami crew on board. Dr. Stone and the others goal is a island where the ISS space station crew landed years in the past.

Kaseki's efforts to build the Perseus hits a roadblock.

The Kingdom of Science creates radar and sonar to determine the source of the morse code.

Senku looks for the Sagara oil fields.

The Kingdom of Science needs rations for the planned voyage of discovery.

Ishigami village takes up agriculture.

Determined to go to the other side of the world to determine the cause of the petrification, Senku endeavours to put Tsukasa's men to work to build a ship. For that, he needs a captain that can navigate the ship with sails, and he hears of a guy called Ryuusui which peaks his interest.
