Senku demands a truce from Tsukasa in return for reviving his sister, Mirai, who Tsukasa comes to know is alive, but a new problem shows up when Hyoga shows his true self.

The Kingdom of Science is victorious, however it is not over for Senku. Senku must use all of his knowledge to cure Tsukasa who is severly injured.

Tsukasa and Hyoga are coming to capture the miracle cave. The Kingdom of Science must buy Senku and Chrome some time to turn the tide, or it is all over.

The Final Battle for the miracle cave starts as Senku and the Kingdom of Science conduct a frontal assault on the cave.

While Senku's diversion buys Gen and others some time, soon Homura realizes something is not right.

Senku decides to use the Steam-Gorilla to capture The Miracle Cave. Using Lillian's recording, Senku gains the trust of more of Tsukasa's men. Ukyo reveals he saw Yuzuriha's secret mission to reassemble the fragments of statues Tsukasa destroyed.

Chrome must use all of his scientific knowledge to escape from his prison and save Senku and others.

Taiju and Yuzuriha are on the verge of tears after they hear Senku's voice, and Senku informs them of his plan to win the war without any bloodshed.

Chrome and Magma struggle with Ukyo, while Senku, gets his hands busy with building up an invention; a new hope.

The final touches to the automobile are made and it is used to transport the science supplies to a fortified cliffside that's close to the Tsukasa empire. From there the automobile is upgraded into a tank, but unbeknownst to the rescue group preparations by the empire have been made to counter any vehicular attack.

Senku continues in trying to advance the Stone World, this time he makes "space food", it is in actuality cup noodles. After Senku finishes his project, Gen has an epiphany and devises a plan to take down Tsukasa's army without violence.
