When the "Trigun" manga begins, Vash travels around the planet searching for Knives. He befriends Meryl Stryfe and Milly Thompson, two agents of the Bernardelli Insurance Society, sent to evaluate claims regarding the dangers he has caused and whether or not his bounty should be canceled. He also meets a priest named Nicholas D. Wolfwood, who fights alongside him. Vash is targeted by Legato Bluesummers from the Gung-ho Guns assassins who are followers of Knives. After Legato confronts Vash, Knives reappears. A shocked Vash requests evacuation for Meryl and Milly because of the danger his brother presents. Knives then tries to use Vash's Angel Arm to destroy another city, but Vash resists and redirects the blast upward, where it hits one of No-man's moons.
