These are a bunch of Gungravey links. Sites linked by banners come before sites I linked by text.
This is a Gungrave Fanlisting. I like the look of their layout.
Here's another fanlisting but this time, just to Brandon. To Protect is not only a fanlisting to Brandon but a shrine to him is in the works.
This is the official Japanese website. It covers all the games as well as the anime. Not in depth though, but enough for advertising sake. Check out their merchandise. They've got replicas of Grave's gun.
Grave x Brandon is a Japanese fan art site. This artist not only has Gungrave art on their site but Digimon, Final Fantasy 7, and others. They even have their own original artwork up. Check them out.
Skeletons in the Closet is a Japanese fan art site revolving around... Vincent Valentine. What's that have to do with Gungrave, you ask? Well the artist applies Gungrave-like themes to her fan art. And since it fuses Vincent and Gungrave, it fits.
Official English DVD Site
Here's the English site. That is where I jacked the bullets for me buttons. It's in Flash so it'll take a second to load, even if you have a fast connection.
Cerebrus Overdose
This is the first ENGLISH Gungrave Fansite.
