In this episode, the Kingdom of Science prepares for the upcoming confrontation with the Petrification Kingdom. The episode begins with the revival of Yuzuriha and Chrome, who immediately put their skills to use in building a drone, a central element of their strategy.

Ukyo also joins the team, whose expertise proves invaluable. Amaryllis, who has infiltrated the enemy ranks, provides crucial information about the Medusa device, which operates on scientific principles. This knowledge allows Senku and his team to devise a plan to take possession of it.

Moz, a feared warrior on the enemy side, poses a significant threat. Gen, the mentalist, manages to negotiate with Moz, creating the conditions for a temporary alliance. However, the Kingdom of Science remains wary of Moz's true intentions.

In this episode, various scientific tools and weapons are crafted. Kaseki and the team work on creating a rapid-fire pistol, applying their knowledge of chemistry and ballistics. Although the weapon is effective, it is a key component of their non-lethal strategy.

Yo, a former police officer, is entrusted with operating the weapon, though the team has reservations due to his overzealous nature. Meanwhile, the team produces camouflage cloaks and carbon wires to prepare for battle.

As the episode progresses, the Kingdom of Science further builds its arsenal. A three-way battle ensues between the Kingdom of Science, the Petrification Kingdom, and Moz.
