Episode 56

**"Treasure Island"** (『宝島』, *"Takarajima"*) is the fifty-sixth episode of the *Dr. Stone* anime, and the twenty-first episode of the third season.

## Summary

Restoration to Treasure Island goes underway while Senku and the Kingdom of Science gained information from Matsukaze, an islander who was petrified for centuries. Upon learning the Petrification Weapon descended from the skies in "more" ways than one and after pinpointing the repeated mysterious transmissions, Senku calculates that the Why-man is on the moon! Announcing his next project to fly to the moon, Senku and his friends prepare to depart back to Japan, but Soyuz, on the other hand...

## Plot Details

Senku’s plan involves collecting skilled people and materials from all over the world, so they plan to leave after freeing everyone Ibara petrified. Soyuz decides to stay as the new master, becoming the island's intermediary with the islanders so that they become allies of the Kingdom of Science on their free course. Kirisame and Matsukaze agree to accompany Senku to other countries. Surprisingly, Matsukaze swears loyalty to Ginro, who bears such a close resemblance to his master from before being petrified he must have been Ginro’s direct ancestor. Senku puts on a special show by reinventing fireworks, which were always Byakuya’s favorite. Senku feels unexpected nostalgia, realizing Byakuya stood on the same beach thousands of years ago and paved the way for Senku to survive and one day reach outer space. As they depart on the Perseus, Senku reasons going to space will require Ryusui as pilot, himself as scientist, and their strongest warrior. Returning to Ishigami village with Medusa, everyone rejoices as Senku can now petrify and revive the fatally-injured Tsukasa, still safely preserved in the freezer where Senku placed him.
