Lock On is the 159th chapter of the Dr. Stone manga.


Dr. Xeno reiterates that Taiju is not the enemy scientist, but Senku is. Stanley asks Xeno to identify Senku. Xeno rushes to retrieve a recording of the Perseus’ transmissions while reminiscing about his past with Senku. Stanley complains that he can’t hear their voices, but Xeno says that he’ll use Senku’s voice to calculate his height. Xeno estimates his height to be about 5’8” and his age to be 19. Stanley (using Luna as benchmark) narrows his targets down to three.

Ryusui alerts the crew about the sniper, causing them to scatter. Luna, shocked that they had figured out the plan, instinctively looks at Stanley for guidance. Stanley curses her for giving away his position, but realizes that this could work to his advantage, as their inexperience will cause the scientist to look at him. Surely enough, Senku looks in Stanley’s direction, validating the guess. Stanley notes that Senku is using geometric principles to get out of Stanley’s line of sight quickly, but Stanley uses that information to predict where Senku will hide.

Before taking the shot, Stanley asks Xeno whether or not he’s sure he wants Senku dead, which Xeno confirms, believing that Senku would never agree with Xeno’s ambitions. Stanley takes the shot, as Senku mixes an unknown starch and water, creating dilatant fluid, which he remembers was tested for use in bulletproof vests. He gets the bag in front of himself just in time for the bullet to pierce the wall and fragment, hitting the bag in multiple places.


Chapter Notes

  • Believing Senku would not agree with him, Dr. Xeno orders for his death.
  • With help from Xeno, Stanley is able to identify Senku.
