Brief episode recap

In the opening moments of Dr. Stone season 3 episode 21, Senku once again calls upon his allies for help in achieving the seemingly impossible task of reaching the moon. He reiterates his unwavering determination for the Kingdom of Science to accomplish this feat, stressing that it will require patience and a step-by-step approach. Despite skepticism from others, Senku remains resolute, stating that they will need to embark on a global journey to gather all the necessary materials for their lunar mission.

Meanwhile, he and the rest of the group worked diligently to save all the petrified individuals on Treasure Island. The villagers were amazed by the Revival Fluid, leading to the realization that Ibara's Medusa Device, now in the possession of the Kingdom of Science, was the final one on the island.

In Dr. Stone season 3 episode 21, Soyuz went to visit his father and expressed regret for not being able to rescue him. Ryusui Nanami then began reviving the enemy soldiers, reassuring Ginro and others that everything would be okay. The soldiers, under the leadership of Kirisame and Oarashi, pledged their loyalty to Soyuz and acknowledged him as the Master's child.

The following day, Senku gathered everyone to announce their final mission before departing: to establish Treasure Island as an ally of the Kingdom of Science. Senku's aim was to gain the support of the islanders to assist in crafting the necessary items for their upcoming world tour. He made it clear that they were not seeking to rule over the islanders, but rather to give them the freedom to choose for themselves. However, he hinted at Gen's ability to use his mentalist skills to ensure the islanders' cooperation.

In Dr. Stone season 3 episode 21, Soyuz stepped up to handle a crucial aspect of the mission and convinced others to help. A montage showed the islanders and Kingdom of Science working together. Later, Chrome found Senku working with zeolite and learned that he was setting up a backup plan. Gen, Francois, and Suika began preparing for this possibility as the episode jumped to the test of what the islanders had built the next day.

In this episode, it was revealed that Treasure Island houses a long-range radio tower, which is crucial for establishing communication between the island and Ishigami Village and the Kingdom of Science. Later that night, Francois and the others treated the islanders to a meal in an effort to further persuade them to collaborate with the Kingdom of Science.

Soyuz informed Senku that he intended to remain on Treasure Island to assist its people with starting over and continued development. Senku agreed, noting their shared goal, and Soyuz mentioned that he remembered how to make the Revival Fluid, allowing Senku and the others to depart without delay.

In Dr. Stone season 3 episode 21, Senku asked Kirisame to accompany him as a strong and cunning warrior, while Ginro convinced Matsukaze to join him as a guard. As the lights on the beach went out, Chrome began a fireworks display to entertain the islanders and persuade them to join the Kingdom of Science.

The villagers gazed in wonder at the fireworks, while the members of the Kingdom of Science from the 21st century reflected on their previous lives. Senku recalled watching fireworks with Byakuya when he was a young child, eagerly dissecting the science behind the fireworks despite his tender age.

In Dr. Stone season 3 episode 21, Senku and Kohaku visit the site of Byakuya and his team's spaceship. They discuss the importance of passing down their will to future generations and Senku agrees. The Kingdom of Science leaves Treasure Island, but they are united by radio and science. On the Perseus, Senku explains that they will travel the world gathering people and resources for their moon mission. He confirms that the rocket will only fit three people - a pilot, a scientist, and a fighter. Senku reveals that they already have a fighter chosen and the episode ends with the reveal that the Perseus has returned to Ishigami Village. Senku declares that it's time to wake up and heal Shishio Tsukasa.

Editor's P/S

As an enthusiastic fan of Dr. Stone, I am thrilled about the latest episode of season 3. The return of Tsukasa, hinted at in the title, has me eagerly anticipating what's to come. Tsukasa is one of the most powerful and intriguing characters in the series, and his revival promises to bring new dynamics and challenges to the story. The prospect of an astrological voyage further adds to the excitement, as it opens up endless possibilities for exploration and adventure.

The episode also showcases Senku's unwavering determination and leadership skills. Despite the skepticism of others, he remains steadfast in his vision of reaching the moon and embarks on a global journey to gather the necessary resources. His ability to inspire and unite people from different backgrounds is truly remarkable, and I can't wait to see how he overcomes the obstacles that lie ahead.
