Dr. Stone Wiki
Dr. Stone Wiki

Full Assault (全軍出撃 Sengun Shutsugeki) is the twenty-eighth episode of the Dr. Stone anime, and the fourth episode of the second season.


Chrome gets himself caught by Ukyo of the Tsukasa Empire. From there, Tsukasa interrogates him and due to his loquacious nature, puts himself in a predicament. Back at the Ishigami Village, plans to create a car are announced and for the first plan of action is to create a steam engine to act as a motor.

Plot Details[]

Through the Cell Phone, Nikki didactically informs Senku and Gen that their Lillian impersonation is at best 55% accurate. However, with her on their side, she can help them perfect it, but she still worries about Tsukasa and his followers. The two of whom they should keep their eyes on the most are Hyoga and Ukyo Saionji.

Missed shots

A brief explanation of Ukyo's capabilities are given by Nikki and his backstory is elaborated on by Gen as a submarine sonar operator. Meanwhile, Chrome and Magma continue to try and evade Ukyo's arrows being fired at them. Magma, figuring that he's already pin-pointing Ukyo's location, rushes off to where he believes Ukyo is located and is put on a wild goose-chase. On the other hand, Chrome realizes that all of the arrows shot at them are from varied locations, which is a tactic to make use of the smokescreen the two tried to use again on Ukyo. Thinking scientifically, Chrome tries to figure out Ukyo's angle by firing off random arrows from different positions and concludes that his motive is to capture and interrogate them. Therefore, Chrome raises a white flag and surrenders himself to Ukyo, who then leads him back to the Empire to meet with Tsukasa. Once there, Chrome is questioned by Tsukasa, mainly about his relationship to Senku.

Senku mobilizes the army

Magma rushes back to the Village and informs them all of Chrome's capture. In light of this, Kohaku tries to run off and rescue Chrome; however, Senku stops her with a megaphone. With the Kingdom of Science flag in his arm, Senku proclaims that all of the soldiers will mobilize and go after Chrome. Gathering and consolidating all of the kingdom's supplies in the center, Senku reveals that they're going to build a car. The first step to creating the car is by melting beeswax in order to carve the shape of the parts for the car (also using a basic lathe), so molds can be made from them and the parts made of metal using the molds. Next, a stove is fitted with a boiler and a steam engine. Senku explains that it works like a pump in reverse. Although Kohaku is worried about Chrome, Senku is not worried about him, so long as he doesn't talk. Kohaku then rebuts that Senku's last comment is contrary to Chrome's personality, making Senku and everyone around him realize how doomed they may be.

Chrome messes up

Meanwhile, back at the Tsukasa Empire, Chrome messes up and a spear over a cliff by a waterfall holds him. Hyoga holds the spear and presents Chrome with two choices, speak or die. Tsukasa also tries to reason with Chrome, claiming science tainted and corrupted the old world, and offers him a chance to join his empire. Despite sounding interested in the offer, Chrome still declines it and is dropped down the ravine below. At this moment, Tsukasa signals Ukyo to shoot an arrow that pins chrome to a nearby tree log, stopping the fall. Tsukasa then launches another log by hand, which lands near where Chrome is hanging in order to make a route to retrieve him. Tsukasa then asks Ukyo where he originally found Chrome, but he lies that Chrome was found when he was investigating the Cave of Miracles. This leaves Chrome astounded by Ukyo's motives.

Returning to the village, the villagers complete a functioning steam-powered vehicle.
