Jewel made entirely by hand by the Italian craftsman Gianmarco Fontana. 
This ring made of 925 Silver depicting a tribute to Trigun is part of the "Otaku" collection.

Nightow's work is an impactful comic that manages to mix a very particular character with a western-science fiction theme, Vash The Stampede called "the Humanoid Typhoon", a blond gunslinger with a bright red coat and pointed hair, the first human being to be defined as a natural disaster. The protagonist is not a normal man, but a plant, a special form of life that humans use to survive on the planet Gunsmoke where they were forced to move after the inevitable death of the Earth: he therefore has only the fame; yes, he is a skilled and very fast gunslinger, but also a convinced pacifist who loves a peaceful life who always trusts in the goodness of soul of his neighbor. Gunsmoke is almost unlivable for humans, formed entirely by deserts and illuminated by two suns, and human settlers must every day struggle for survival in a far west climate, where technology seems to have undergone a disarming involution and where the only forms of sustenance seem to come from plants.
Yasuhiro Nightow outlines Vash's mission from the first volumes: after having avoided in "Trigun" (first series) that his brother Knives destroys the Earth for a deep hatred towards the human race dictated by the exploitation of his similar plants, in the second series (the Maximum) Knives' right arm, Legato Bluesummer, unleashes the gang of Gung-Ho Guns at the ribs of the blond gunman, twelve assassins who do everything to ensure the necessary time for Knives regeneration and thus prevent Vash from stopping him from new one.
