Senku and the kingdom are going to need rations to be well during their attack on Tsukasa’s empire. There’s a science for that.

The kingdom of science moves to Tsukasa’s scout, Homura, so that they can deploy their newly built cell phone in their base.

With Homura captured, the kingdom of science finally succeeds in setting up a hotline with their spies in Tsukasa’s empire. Meanwhile, Chrome runs into some trouble.

Nikki becomes the first member of the Tsukasa Empire to convert to the kingdom of science. Meanwhile, with Chrome in mortal danger, Senku and the kingdom begin plotting a way to bring him back to safety.

The kingdom of science builds a steam engine. They use it to set up base closer to Tsukasa’s empire.

Chrome tries to use his knowledge of science to escape from his prison, but he just doesn’t have the tools. Yo, a former cop who had been revived into Tsukasa’s army, tries to work up the ranks.

Chrome makes it back to the kingdom of science’s base, where he bears witness to the Steam Gorilla for the first time. Meanwhile, with the help of the others and with his fake Lilian voice, Gen manages to convert even more people away from the Tsukasa Empire.

The kingdom of science begins its siege on Tsukasa’s empire. They’ll have less than twenty seconds from the beginning of the war to scare the empire into submission, or risk casualties.

Several of the kingdom’s strongest fighters are locked in battle with Hyoga and Tsukasa. Meanwhile, Senku, Gen and Chrome make it to the miracle cave. They’ll have very little time to put together a weapon to end the war.

A truce is called between the kingdom of science and Tsukasa Empire. All appears to be well, but some of the kingdom’s dynamite is missing.

Tsukasa and Senku defeat Hyoga, but Tsukasa is mortally wounded. The options for treating sepsis and a punctured lung are limited, painful and uncertain.
