Medusa vs. Science (MEDUSA (メデューサ) VS (バーサス) SCIENCE (サイエンス) Medeyūsa Bāsasu Saiensu) is the 136th chapter of the Dr. Stone manga.


After Ibara is hit by the lab, Senku reaches for the Petrification Weapon but Ibara stabs him in the shoulder when he reaches for the Petrification Weapon. Desiring to finish Senku, he challenges him but the latter runs.

Disgusted by the supposed cowardice, Ibara pursues him but soon realized that Senku is luring him through the forest where he can't use the device and compliments his strategy. Ibara shatters a jar that Senku tossed at him, complimenting him for laying out traps.

Ibara then corners Senku after calling his bluff, he asks Senku for his name and the latter tells him while Ibara wishes him farewell. However, he hears a noise and drone comes up with Ryusui on it (having been revived when Ibara unknowingly shattered the formula on him) and he takes the weapon.

Chapter Notes

  • Senku engages Ibara in a battle of wits.
  • Ryusui is revived, thanks to Ibara unknowingly shattering the formula on him.
