Ming Chao's grandfather has passed, so now she decides to travel through the the wild west to Hollywood to become a star. Not without her trusty Eto Gun of course! But wait! The Eto Gun is actually a gun that shoots bullets related to the zodiac animal it got the essence of! And the notorious bandit group, the Syndicate, want it! Along the way, she is joined by Baskerville, Benkate, Fino, Yaghi, and Alternate.A manga created by Tow Nakazaki and distributed in America by Tokyopop. It spanned 9 volumes.
Fantastic Racism: When Fino is introduced, it's established she has an immense hatred of white people. This is because the first white man she befriended (Blush) killed her parents. She gets better, though.
The Fool: Mingchao. She always manages to get out of life-threatening situations with barely a scrape. Benkate even lampshades this at one point.
Funny Background Event: In an early chapter you can see Baskerville getting an Accidental Kiss from the woman whose house he and Mingchao are staying at after the shock from a window breaking behind them knocks them into each other.
Hollywood Tone-Deaf: Unfortunately for Ming-Chao who wants to be a singer, her singing sounds like a dying cat. She didn't know this for a while though, since she had only sung in front of her grandfather.
Kind of subverted in that while it does do a HELL of a lot damage as the strongest gun in the West, it can never actually kill anyone (at least the way Mingchao uses it, it's mentioned a few times that a headshot, especially at close range, could do some major damage, and Benkate says at one point that Yaghi wouldn't survive if hit with it). It still hurts though.
Logical Weakness: The Eto Gun and Zodiac use "essence" to form their bullets, and thus are unable to fire without the proper essences. If caught without any usable essence, their users are sitting ducks.
The Pisces bullet is based off of a fish, and thus is only effective underwater. Unless that fish is a flying fish.
Lolicon: Baskerville gets teased several times about how he might be this towards Ming Chao based on how much affection he shows towards her.
Love Makes You Evil: Baskerville/Razy's love for his sister drove him to do some terrible things searching for rare guns in exchange for the narcotic the Syndicate told him was medicine.
The Bigger Bad of the series turns out to be Mingchao's father, who had his Start of Darkness after racist doctors refused to treat his sick wife, leading to her death.
May-December Romance: A hinted one with Ming Chao and Baskerville. No one's ages in this series are exact but Mingchao is at least 10 and at best about 12, and Baskerville could easily be in his mid-twenties.
Yaghi has a one-sided crush on Benkate. A bonus material states he actually would like for her to be his wife!
Minor Crime Reveals Major Plot: To sum it up, the heroes foiling Alternate's repeated attempts to steal the Eto Gun eventually leads to them uncovering a massive underground drug operation.
The Reveal: Baskerville's real name is Razy and is a former member of the Syndicate.
Start of Darkness: After his wife — Mingchao's mother — died because racist doctors refused to bother treating her, her husband — Mingchao's father — swore revenge against the U.S. by becoming its kingpin of crime.
Stern Chase: For most of the series. Who is chasing who and for what reason changes, depending on the current situation.
What Happened to the Mouse?: Subverted. Blush, the only major antagonist still unaccounted for by the end, is revealed in the Bonus Material omake after the main story, to already secretly have been killed during the Final Battle by the huge energy ball created by combined final attack of the Zodiac and Eto guns. However, no one else is aware of this at all, as Blush was in hiding from the protagonists when he was incinerated.
