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?

Trigun

トライガン

Adachi, Mitsuru

The story is set in a place very similar in appearance to Earth in the Edo period. However, Adachi (the mangaka) regularly reminds the reader all throughout the series that the setting is another planet in the distant future which just happens to look like Earth.

After the death of his mother, Shichimi sets out to join his step-brothers and -sister who live together in Karakuri Tenement, a place provided by the father they have never met. He finds out that each of them had different mothers (all of whom have died), but were fathered by the same man. Not long after Shichimi's arrival, the siblings decide to journey to visit the graves of each of their mothers. On this journey, they encounter many dangers.

Fifteen years ago, those living in Outer Space went to war with people still on Earth. During the battles of the 7th Space War, it was found that certain human beings had mysterious arcane abilities, powers of the mind to control and forsee. These gifted people were called Newtypes. They were valuable to both sides of the war; the Earth Federation designed the Flash System which allowed a Newtype pilot to control a horde of unmanned MS, called Bit-Mobile Suits.This was an effective weapon, but sacrificed the lives of many Newtypes. 

Space fought back for principal, believing the effect of living in Space heightened every human ability and eventually created the prized power of a Newtype, who was not something to use as a tool for war. But in the end, mankind was its own downfall. During the final battle, the Space Revolution Army (SRA) crashed numerous colonies into the planet Earth, with a devastating effect. 

Millions died as a result of the colony drop. Those that were fortunate enough to find refuge in a Shelter were both blessed and cursed; they wouldn't see the sun again for four years. The rest that made it through had to endure and suffer with living on a ruined planet, plagued by an endless winter and an ever-changing, chaotic atmosphere. With that, the war had ended. For now. But everyone who continued to live on was possessed by that tragic war, and the word "Newtype"... 

The year is After War 0015, and life on Earth is finally on its way to creating a more perfect world, except for the ruthless mercenaries who use mobile suits to make a living raiding; called Vultures, some of these people are merely chasing money, while others are running from the past. Enter 15 year old Garrod Ran, an orphan of the war. He is a lively and friendly boy who is trying to survive in the wake of the war, living off his daring-do's and knowledge of MS. Because of this, Garrod is hired to rescue a kidnapped girl from a Vulture ship, called the Freeden, and its stoic captain, Jamil Neate. 

But Garrod soon finds out that this job is entirely not what it seems; that the girl, Tiffa Adill, is actually a powerful Newtype, able to dream the future. And when Tiffa shows Garrod the Gundam X, Garrod can do nothing but bear witness to the suddenly changing times. He may learn that people's true intentions run far deeper, and that the Vultures and Captain Jamil Neate are their only hope for surviving the coming age, and the birth of the New Earth Federation. 

Must mankind repeat the tragic mistake of the past?
