Fujiko, Fujio F.

Doraemon is cat shaped robot from the future traveling all the way back to the 20th century in order to help Nobi Nobita, a lazy kid with nothing really going for him. Nobi is bad at sports, his grades are terrible, he can't even win a match of rock-paper-scissors. Doraemon has a hard task ahead of him but he is well prepared with a huge arsenal of the most inventive and funny gadgets available. The problem is he's not the most competent robot cat helper out there either and the pair gets in constant trouble because of it. Thus begins one of the most interesting friendships ever to appear in a manga series.

Doraemon

ドラえもん

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.
