Dr. Stone Wiki

The Trump Card Aboard the Science Vessel (切り札は科学の船に Kirifuda wa Kagaku no Fune ni) is the forty-third episode of the Dr. Stone anime, and the eighth episode of the third season.


Senku and his friends have Amaryllis, a beautiful girl on the island. Ever since Amaryllis saw the two top strikers, Moz and Kirisame, who serve as the head of the island, use petrification weapons five years ago, she's secretly been eyeing the chance to seize them. When Senku hears about it, he immediately begins an infiltration operation to investigate the area around the head!

However, the scientific labs needed for the project are inside the occupied Perseus. "I hear the state of the ship from afar, but..."

Plot Details[]

Five years previously, Amaryllis attempted to leave the island with her friends, but they were caught by guards Moz and Kirisame, who petrified them and threw them into the ocean. Amaryllis avoided the weapon's light by inches. Amaryllis has been plotting all these years to marry the Master and steal the weapon. Senku is glad to confirm it is a weapon and not magic since weapons follow scientific principles and can be defeated. As the Master only marries the cutest girl, Kohaku volunteers as she stands the best chance of stealing the weapon. Amaryllis donates a dress, but to make makeup, Senku requires the mobile lab from the ship, which has now been captured by the Master's Minister, Ibara. Seeing Ibara smashing the crew statues, Kohaku flies into a rage and fights Kirisame while shouting for the mobile lab. Kirisame has never heard of a lab so Gen convinces her Senku is her boyfriend, Lab, embarrassing Kirisame into leaving. Miraculously, both Ginro and Suika had survived due to Ukyo shooting the weapon slightly off target. Ginro is unanimously written off as useless by everyone, but Suika, having heard Kohaku shouting, is determined to get the lab off the ship to Senku.
