Perseus, Ship of Science ( () (がく) (せん) ペルセウス Kagakusen Peruseusu) is the 102nd chapter of the Dr. Stone manga.


Learning that Treasure Island is inhabited from Soyuz, the crew of the Perseus speculate as to the origins of the inhabitants and their potential relationship to Ishigami Village. Chrome questions this, as he thought all of humanity except the astronauts were petrified. After contacting Ruri, who reveals one of the stories says to head for the home of Byakuya; Japan. Senku and Ryusui soon realize the two groups branch off when one group reached the shore.

Chrome suddenly realizes that those who made it to Japan were the ancestors of those in Ishigami village. Senku confirms that and deduced the ones who stayed behind realized they needed to stay, just in case it failed so humanity could thrive. Soyuz realizes that those who stayed are his people. After everyone clears this matter up, Chrome makes a startling speculation on the Why-man being a member of the newly revealed tribe. This garners worry is everyone realizes that this is a possibility as Kokuyo questions Soyuz on not telling everyone his story sooner. However, he soon sees how hard it was for the young man to admit this.

Senku, Gen, and Kohaku also note that wanting to know more is what brought the Kingdom of science together and declares Soyuz is one of them, to his relief. Kohaku then asked how long until they reach Treasure island, to which Ryusui casually says it will be a few hours. The crew were very surprised to hear this while Chrome and Soyuz are excited they will not take long.

After Yuzuriha expresses in interest in the creation of the Perseus, Senku, Ryusui, and Kaseki explain its inner workings. Nikki and Kohaku tell Yuzuriha that she is doomed with their stories but she reveals how she sat through Senku giving a five hour lecture on rockets. The pair are surprised to hear that she is a very harden veteran with lectures.

A storm suddenly arrives. Ryusui calms the crew, but Senku determines there's no better time to approach the island undetected. Treasure Island is within sight!
