Gun Frontier

Gun Frontier (ガン フロンティア) is a 1972 manga by Leiji Matsumoto. It introduces Tochiro Oyama, best friend to Matsumoto's classic hero, Captain Harlock, who is in turn depicted as a gunslinger in the Old West. In sharp contrast to other Matsumoto's stories, Gun Frontier is a comedy adventure rather than a space opera. Also, unlike other Harlock stories, in Gun Frontier, Harlock is depicted as Tochiro's sidekick.

The manga follows Sea Pirate Captain Harlock and the samurai Tochiro, who arrive in the United States on the Western Frontier, known also as Gun Frontier. Along with a mysterious woman they meet along the way, the two friends challenge sex rings, bandits, and corrupt sheriff. They are searching for a lost clan of Japanese immigrants, and they will tear Gun Frontier from end to end until they find it.

Since the original manga, there has been a novel and a 2002 anime adaption of the series.

Characters
Tochiro Oyama
 * He is the main character. He is one of the survivors of Samurai Creek, a town of Japanese immigrants who were mysteriously all slaughtered, with only a few exceptions. Tochiro's purpose is to find the scattered remains of his people, no matter who or what he has to destroy to find them. Tochiro uses a Shikomizue very skillfully, but has awful aim with his gun, a fact which is often poked fun at throughout the series. Despite wearing glasses, he refers to himself as "not being able to see past the end of a shovel [he is] holding". He is also abnormally short, as well as bowlegged, and while he wears his cloak he can often avoid a fatal gunshot wound as his attacker would likely have no idea how small or awkwardly shaped he actually is. He is also a very heavy drinker.

Franklin Harlock Jr.
 * He is a sea captain turned gunslinger. He owes his life to Tochiro, and therefore takes him to America on his ship. Harlock is a master gunman, a quick draw like no other, and sharp as a tack. He is able to detect that Sinunora is trying to pry him and Tochiro apart for her own unclear reasons. He is very loyal to Tochiro. He is also quite enigmatic and silent, often grumbling and dismissing any mention of the past. Harlock has an x-shaped scar on his cheek, which is later revealed to be from a sword duel he and Tochiro had on Harlock's ship while they were still enemies.

Sinunora
 * She is a woman who joins Tochiro and Harlock at the end of the first episode. Beautiful and capable, she's not the damsel in distress as she is very good at using manipulation to get out of traps and get what she wants (it is revealed later in the series that she is an expert on human behavior). It also comes to Harlocks attention that Sinunora gets close to the pair so that she can spy on them and report back to the mysterious "Organization that guides the world" but in truth, she eventually is warmed by Tochiro's struggle and uses her position as their tracker to protect them instead. Her real name is never mentioned, except by a man named Baron De Noir F. Tat Endale, always referred with his full name and title, who is believed to be her husband. He mentions the first part of her name being "Anrei", but it is cut off and her real name is never mentioned again.

Shizuku
