The moment Senku stops explaining science like a textbook and starts weaponizing it, the show becomes genuinely unhinged in the best way. Every invention feels earned because you watched the resource scarcity before the breakthrough, then watched both sides immediately pivot to war applications. It's a show that makes you root for a teenager grinding sulfur into gunpowder because the alternative is letting an immortal cult dictate humanity's future.

Senku is set on bringing back two million years of human progress and reviving everyone turned to stone. Tsukasa Shishiou stands against him, convinced that only the strongest of the petrified deserve to return, and his empire moves to stop science from advancing. As spring arrives, Senku, Chrome and the villagers of Ishigami Village finish preparing to strike. Their plan hinges on a rebuilt cell phone meant to win over Tsukasa's soldiers from within, but every day spent refining it lets the empire grow larger. Reuniting with old friends and gaining new allies, the Kingdom of Science races to stop Tsukasa's forces as both sides pursue their own vision of the world, blending action, adventure, comedy and science fiction.
