Dr. Stone Wiki

Information Warfare ( (じょう) (ほう) (せん) (そう) Jōhō Sensō) is the sixty-third chapter of the Dr. Stone manga.


Senku used the blue jewel powder on Homura's arms and legs to track her. Since it only glows under ultraviolet light, Senku built a black-light for following her. Kohaku tells Senku that she could kill Homura the next time they meet, but asks if he'd be okay with it. She also mentions she's never killed anyone before, and would likely hesitate. Senku says she shouldn't kill anyone.

The cell phone team receive an odd call from the other end, and Gen realizes that it's a warning that Homura is after them. They continue on pretending like they don't know. One of the mornings, Homura notices that her hands are glowing, and washes them off in the river. Using the information Gen sends them, they establish that Homura is only tailing the team rather than trying to intercept.

Using the cell phones, the two groups organize a pincer attack, tricking her into climbing a tree to destroy the cell phone. It was a bluff, and they topple the tree. Kohaku catches Homura before she's killed by the fall. Homura is captured, and the cell phone team carry on towards the Tsukasa Empire.
