Ace in the Hole on the Ship of Science (切り札は科学の船に Kirifuda wa Kagaku no Fune ni) is the 107th chapter of the Dr. Stone manga.


Needing Kohaku to infiltrate the harem selection, Senku and the recon team express doubt that she can successfully adapt to the role of a maiden. To help her, Senku needs the materials still aboard the Perseus.

However, the Petrification Kingdom, lead by Minister Ibara, has already seized the ship. Kohaku leaps towards the ship, enraged after seeing Ibara break the statues of her comrades, but is stopped by Kirisame. After a brief scuffle, Kohaku yells out "lab", a word not known to the natives, hoping someone is still alive on the ship to hear it. Gen and Senku assist in her bluff.

Aboard the ship, Ginro hides among the cargo, afraid to respond to Kohaku's plea.
