The Perseus arrives at the treasure island. A recon squad consisting of Senku, Soyuz, Kohaku, and Gen set off to locate the platinum and make contact with the islanders. Ukyo later discovers something on the seafloor and send Ginro to investigate.
When Earth was showered by the 
petrification beam, this island was uninhabited.
.عندما غطّى شعاع التحجير الأرض، كانت هذه الجزيرة مهجورة
Zur Zeit der Versteinerung
war diese Insel unbewohnt.
Cuando cayó el rayo petrificador,
Cuando cayó el rayo petrificador,
Lorsque l’humanité a été pétrifiée,
cette île était déserte.
La luce pietrificante è piovuta dal cielo,
Quando a terra foi atingida pelo raio de 
petrificação, a ilha era desabitada.
Когда окаменяющий свет прошёлся
по Земле, этот остров был необитаем.
