Aoyama, Goushou

Hailed as the savior of the Japanese Police Department, high school detective Shinichi Kudou uses a combination of observational skills, critical thinking, and all-around knowledge to solve cases that leave the police stumped.

One day, while at an outing with childhood friend Ran Mouri, Shinichi bears witness to a suspicious transaction between two men and is caught. As a result, he is forced to ingest a poison that is supposed to kill him, but unexpectedly shrinks his body to the size of a grade-schooler instead. Now believed to be dead, Shinichi takes up the alias of Conan Edogawa (a compound of the names of the famous mystery authors Arthur Conan Doyle and Ranpo Edogawa) in order to hide his identity and begins his new life as a seven-year-old living with Ran and her private detective father.

Meitantei Conan follows Conan as he continues to solve murder cases, all while slowly working toward exposing the men who shrunk him and eventually restoring his body.

Kaito Kuroba, a normal teenage student whose father is often absent. When his father dies under mysterious circumstances, he is made aware of his father's secret identity; a famous international criminal known as International Criminal 1412: the Phantom Thief, and that he was murdered by a mysterious organization for refusing to aid them in retrieving the "Pandora Gem"; a mystical stone said to shed a "tear" during the passing of a particular comet (often called the 'Volley Comet'), the consumption of which bestows immortality. He vows to prevent the organization from gaining immortality, and assumes his father's identity as he begins his quest for the gem. His only clues as to the gem's location are that it glows red under the full moon and that it is a doublet: a gem hidden within a larger gem. Thus, it would have to be a relatively large one with a bizarre history, and always stored in a place that never receives moonlight. He thus researches and steals famous priceless gems with odd histories from incredibly well-defended areas, and always returns them after the very next full moon.

Shaman King

シャーマンキング

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?
