Dr. Stone Wiki

Ray of Despair, Ray of Hope (絶望と希望の光 Zetsubō to Kibō no Hikari) is the forty-second episode of the Dr. Stone anime, and the seventh episode of the third season.

Summary[]

Senku and the Perseus crew finally arrived at Treasure Island. To quietly find the sleeping platinum on its grounds, the crew deploys the recon team with Soyuz, who is revealed to be one of the island's natives. They make use of their scientific investigation to figure out who among the islanders should be their first contact and ally. Meanwhile, Ukyo who finds something beneath the reader, becomes shocked with doubt after discovering what lies beneath the island's waters. This is said when Ryusui already senses somebody who has already noticed their stealthy approach.

Plot Details[]

The crew sends Senku, Soyuz, Kohaku, and Gen to find the islanders. Ryusui finds Suika stowed away on the ship. Ukyo and Ginro find statues underwater and realize they couldn't be from the petrification event 3700 years ago since the island was uninhabited before the astronauts arrived, so these statues were petrified much later. Losing radio contact, Soyuz and Gen find everyone on board petrified into statues, except for Suika, whom Ryusui saved by throwing her overboard. The shock causes Soyuz to remember that he and his parents left the island to escape something. Finding evidence of foraging, Senku and Gen used forensics and psychological profiling to determine it was a young girl of average height with dark hair who lived by the mountains. They soon spot the girl, Amaryllis, and determine from her conversation that she is engaged to marry an anonymous Master who uses petrification. Senku openly approaches Amaryllis, who is amazed to see other people. A sudden commotion takes them to Amaryllis village, where a mob plans to rebel against the Master. For their own safety, Senku incapacitates them with chloroacetone, aka World War I tear gas. Seeing Senku's "sorcery," Amaryllis begs them to defeat the Master in exchange for the secret of petrification.
