Trigun

Summary: 

    Known for its Space Western theme, Trigun is about a man named "Vash the Stampede" and the two Bernardelli Insurance Company employees who follow him to minimize the damage caused by his appearance. Most of the damage attributed to Vash is caused by bounty hunters after the "60,000,000,000$$" (sixty billion "double dollars") bounty on Vash's head for the destruction of the city of July. However, he cannot remember the incident clearly due to amnesia. Throughout his travels, Vash tries to save lives using non-lethal force. He is occasionally joined by a priest, Nicholas D. Wolfwood, who is an excellent gunfighter like Vash. As the series progresses, it is revealed that he was actually assigned by Knives to "protect and guard" Vash. Later, he also become a target by a member of the band of assassins, the Gung-Ho Guns, for not following the change in "orders" ( to eliminate Vash).

As the series progresses, more is gradually learned about Vash's mysterious history and the history of human civilization on the planet Gunsmoke. The series often employs comic relief and is mostly light-hearted in tone. It also involves moral conflict pertaining to the morality of killing other living things, even when justified (i.e. self-defense/defending others).
