Ep. 6: Chrome escapes prison using chemical tricks and a mysterious battery aid
Tsukasa revives Yo, a former police officer known for his strength. A flashback of Yo's previous life is shown where he was fired for killing a fleeing criminal. Chrome manages to go outside by using the need to excrete as an excuse, where he collects materials. Chrome mulls over the need of a battery in order to escape. Later that night someone sneaks a battery into his cell. Chrome tries to use the battery to blow up the bamboo-gate. However, Yo quickly stops it. Chrome exercises to use his sweat and make "sodium hydroxide" to melt the rope holding the bamboo together, consequently Chrome avoids the anti-vehicle traps and escapes. Yo corners Chrome. However, Chrome fakes pneumonia and strikes Yo who was taken-aback, escaping to Senku's hideout.
