Loop Salad

ルプ★さらだ

Nightow, Yasuhiro

Much of the damage attributed to "Vash" is caused by the activities of bounty hunters who are after the 60,000,000,000$$ (sixty billion "double dollars") reward on Vash's head for the destruction of a city called July. Vash does not clearly remember the destruction of July, and only wants "love and peace", as he puts it; though he is a gunfighter of inhuman skill, he uses his weapons only to save lives wherever he can.

As the series progresses, more is gradually learned about Vash's mysterious history and the history of the human civilization on Gunsmoke, the desert planet the series is set on. The series is often humorous in tone, but at the same time it involves very serious character development and especially in later episodes it becomes quite emotionally intense. Vash is occasionally joined by a priest, Nicholas D. Wolfwood, who is almost as good a gunfighter as Vash himself, and later is targeted by a band of assassins known as the Gung-Ho Guns for reasons which are mysterious at first.

Trigun evolves into a very serious discussion of the nature of morality, posing questions such as: What is the nature of morality? Can we judge different moral codes? If a person is forced to betray their moral code, does that betrayal invalidate that moral code, and can the person still try to live up to that moral code? Can the person find redemption from their wrongs, and if so, how?
