From Dark Horse:
Somehow, the past has placed a sixty billion double-dollar bounty on Vash's head and the gunslinging pacifist can't seem to get away from money-grubbing, itchy-trigger-finger citizenry. Find out why Vash is worth so much money dead. Feel the clumsy worry of the unfortunate citizens of the pulverous planet. Follow the follies of an unlikely hero in a forbidding world! Join Vash the Stampede with his troubled past and uncanny ability to dodge a gazillion bullets and a cavalcade of unlucky characters on a dusty, desert planet in the distant future.

Changed publishers to Shonen Gahosha and continued serialization in Young King Ours. Due to the original publisher retaining the name Trigun, Nightow had to change the title to Trigun Maximum for the rest of the series. The first 3 volumes were published under the title 'Trigun' and the rest is compiled into 14 volumes of 'Trigun Maximum'. The chapter numbering also restarted.

Note: Won the Best Comic category at the 40th Seiun Awards in 2009.
