Cyber Guerilla (CYBER (サイバー) GUERRILLA (グリラ) Saibā Gurira) is the one hundred and eighty-seventh chapter of the Dr. Stone manga.


The chapter begins with Senku stating that its the final battle against Stanley, and that they have the upper hand. However, Gen tells him that Kohaku has run off to confront Stanley's team. No one stops her though, because Senku says delaying them with a little guerrilla warfare will give them time to make a functioning petrification device. Kohaku rushes through the jungle, using her eyesight and knowledge of their bearing to safely approach them without being seen. She scans the group for any weaknesses. However, as Stanley's men are well trained, there is nothing she can use; their formation has nothing to exploit. Tsukasa and Hyoga then appear at her flanks, giving their respective assessments of the situation. While triggering them, they inform her of the record traps Chrome made to trick the enemy into thinking they are being shot at.

In a flashback, we see the making of the record traps. They record the sound of a gunshot, but Ukyo notes that despite it being genuine gunfire, it sounds fake. Senku asks if smacking around a plastic container would work and Ukyo says it would after slowing it down and layering the sound.

The broadcast is heard by the Americans, who return fire; Stanley signals to Maya and two others to break off and flank. It's a mutual distraction. In the meantime, the trio discuss their own strategy. Hyoga and Tsukasa explain that the battle will be over if they manage to destroy Stanley's transceiver. It will leave him unable to contact the American Colony base to retaliate on the Kingdom of Science hostages should anything go sour with Xeno. Hyoga then sadistically suggests they slowly cut off Xeno's fingers and toes until Stanley surrenders, disturbing Tsukasa and Kohaku. Kohaku then says it would never work since Stanley has 4 of their own hostages, to which Hyoga replies that they may need to be abandoned. Tsukasa agrees, but hopes they won't have to.

Soon after they agree to destroy the transceiver (possibly at the cost of their lives), Maya stops her group. Maya notes her instincts are rousing before she spots the science group. Maya shows her eagerness for battle, forcing the trios to go into battle.

Chapter Notes[]

  • Kohaku runs off to save Suika and the other hostages.
    • Tsukasa and Hyoga follow her.
    • Senku doesn't stop her as their fight could buy them more time to work on the petrification device.
  • Kohaku finds the group, only to see no way of exploiting their formation.
  • Tsukasa and Hyoga activate Chrome's record traps, mimicking the sound of gunfire.
    • The gunfire sound is in fact slightly altered plastic container noises.
  • The Americans react accordingly, returning gunfire as Maya and two other flank the source of the noise.
  • Kohaku, Tsukasa and Hyoga decide their goal is to destroy the transceiver on Leonard's back.
  • Maya spots them in the trees and moves to attack.
  • Maya is the former American Women's MMA (Mixed Martial Arts) Champion.


  • The chapter title is misspelled as "guerilla" when it should be "guerrilla".
  • The bandages from Chapter 184 that Tsukasa and Hyoga were wearing seem to have disappeared, and there is no visible injury.
  • Kohaku shows remarkable growth as a tactician; originally only being a very direct "attack first, ask questions later" person.
  • Hyoga is still sadistic, having suggested the "mutilating hostage until enemy complies" tactic, much to Kohaku and Tsukasa's horror.
