Dr. Stone Season 3: New World Episode 13 English Dubbed Episode Title: The Medusa's True Face Episode Description: Taiju begins freediving to retrieve the statues. Kaseki is revived and with his help Senku makes the drone propeller by coating feathers in plastic attached to a fidget spinner. Taiju collects all the statues, including an extra statue that has been petrified for years. In the citadel Ginro is chosen to marry the Master. Moz deduces Kohaku is the infiltrator. Terrified of the Masters impending molestation Ginro decides to use a gas bomb Senku made from vinegar, alcohol and sulphuric acid to cause the Master intense mental confusion. Entering the Master’s room Ginro encounters Ibara who insists all girls traditionally must satisfy him first before marrying the Master. Exposed, Kohaku begins fighting Moz. Ginro neutralises Ibara with the gas and discovers the Master was petrified years ago so Ibara could secretly take over. Moz is attracted to Kohaku for her beauty and strength and is irritated she rejects him for lacking honour. Ginro is fatally stabbed by Ibara but manages to tell Kohaku the Master was almost certainly Soyuz’ father. To save his life Kohaku provokes Kirisame into petrifying them both, trusting Senku to find and revive them. As the weapon activates Kohaku sees it clearly for the first time, a complex scientific device she dubs the Medusa, from a story Senku told her of the mythical greek monster.
