The Treasure Island Arc is the ninth arc of Dr. Stone as well as the second arc of the Source of the Petrification Saga.


This arc focuses on the crew of the Perseus heading to the island where the International Space Station landed on after the Petrification in order to locate the platinum that is needed to revive the petrified people whilst also dealing with the inhabitants that have remained behind and oppose them going to the mainland.

Plot outline

Upon setting sail for South America, many believe that they will be just travelling there non stop. However, Senku reveals that is not the case, as their first destination is Treasure Island, the ancestral homeland of Ishigami Village. On the way to the island, a member of the power team who was identified as being nameless beforehand reveals that he is actually from treasure island and not from Ishigami Village. He is called Soyuz, named after the shuttle that Byakuya traveled in to earth from the space station. He reveals that he moved there as a baby and kept it to himself out of fear of the inhabitants of Ishigami Village. Using Soyuz photographic memory and the power of the Perseus, it only takes a few hours to reach Treasure Island. Chrome and Kohaku are amazed at how strong the Perseus is, upon hearing Yuzuriha's request to find out the ins and outs of the ship, Ryusui takes her on a guided tour of the shop. As the crew are about to dock at treasure island, Ryusui declares that some will go on ahead as a recon squad. Upon hearing this, Suika reveals to have snuck aboard, begging to come along and be useful. However, Ryusui berates and demands that she be returned to the mainland. While this upsets Suika, Francois reveals that Ryusui acted this way because he fears for Suika safety. Cheering her up, Taiju reveals that there are plenty of other tasks for her to be involved with. As Gen, Senku, Soyuz and Kohaku all land on the island and start scouting around a mysterious force approaches the ship. Ryusui demands to know who they are, only for them to respond by petrifying everyone on board.

Kohaku's Gamble

As Kohaku and Kirisame battle, Kohaku believes someone may have survived and shouts the word "lab". Soyuz realized she is trying to see if someone from the Kingdom of Science survived, since they would know the word. Surely enough, Ginro is revealed to be on board hiding, having avoided the process due to being in the water at the time. Ginro is spotted by his allies who are annoyed that its him but resolve to settle. Soon it is revealed Suika also survived, due to Ryusui kicking her overboard to save her and Ginro having avoided the process due to being in the water at the time. [1] [2]

Working together, they are able to clean the mobile lab sneaking right past the enemy who mistake it for an animal.

Infiltrating the enemy

With supplies from the lab, Amaryllis gives Kohaku a makeover, successfully giving her a beautiful appearance.

Believing that one female wouldn’t be enough to infiltrate the harem, Amaryllis proceeds to give the males in the group a makeover, starting with Senku, Soyuz, and Gen makeovers but none of them have the right appearance. However, Ginro is shown to have the right appearance and aids the girls.

Finding the team

Knowing that they need their allies, Senku's group proceed to hatch a rescue plan. They first revive Ryusui and after creating scuba gear, they put the plan action.

The group soon revive Taiju who is able to find all their friends in one go (without breathing equipment).

Unexpected Ally

Running through the Peresus, Senku decides to use his last play and revives Hyoga out to aid him in fighting Mozu and Ibara. Ibara is shocked to see someone revived and falls back because of his fear that the Head can be revived while Mozu is confused by Hyoga's position in this. Seeing that he is strong, Hyoga deduces Mozu is why he was freed. Hyoga weighs his options to either destroy or side with Senku. Mozu attempts to get him on his side, planning to kill him later, but Hyoga chooses to side with the Kingdom of Science instead. [3]

Mozu goes on to fight Hyoga, after failing sway him into allying with him. In the fight, Mozu noted Hyoga was the first warrior to get him to struggle. In the end, Hyoga defeated Mozu when he used the Kan Style with Kinro's spear.

Ibara's final move

Chapter 134

Ibara engulfs the island while Senku survives

Ibara has the island engulfed in the beam, with Ukyo shouting that the weapon can be voice commanded. Meanwhile, Mozu and Hyoga's battle ends in Hyoga's victory, as the pair note on the end before promising if they’d be freed then they would spar again. [4]

Ibara believes he is victorious until he discovers the petrified statues leading to the mobile lab. [5] While there Senku still alive after he tries to use the Petrification weapon. It is revealed Senku poured the revival formula on himself.

Battle of Leaders

The old minister then challenges young scientist to battle only for Senku to escape him. However, this was a ploy when Senku uses a series of devices against him.

Senku then has a tug of war with Ibara, as Ryusui uses a drone to help Senku. It is revealed he was revived, due to Ibara shattering the formula on his statue when Senku threw at him. [6]

Ibara then uses the device while in the middle of a fierce tug-of-war. As a result, Ryusui tries to stop Ibara and Ryusui ended up petrified and breaks into pieces. However, he finds that Ryusui placed a voice com on the weapon. Recalling what it could do, he panics when Senku gloats on this event and activates the device. Ibara then ends up petrified. Following the end of the battle, Senku believes he is alone again. However, he snaps out of it when the Kingdom of science contacts him to ask what is going on.[7]

Kingdom Liberated

Using the revival formula, Senku revives Chrome and the pair work together in reviving all of their petrified allies. Senku then revives Kirisame and tells her and the rest of the Petrification Kingdom the truth about how the minister manipulated them. Senku soon questions her on the location of Kohaku and Ginro, who are revived as well. [8]

Ominous Call

During the celebration between the two kingdoms, Whyman contacts them and attempts to use the Petrification Device on them but fails. This act causes them to realize that the Whyman is an enemy who seeks to petrify them all, due to his specific range order. Ukyo also states Whyman uses Senku's voice, as the others are shocked but the latter is excited.[8]
