Beet is gonna beat the odds, and bust those violent Vandels! 
The New Dark Age 
It's the Century of Darkness where monsters known as Vandels rule the world, and the Vandel Busters are the only ones who can fight them. When a group of Busters are killed in battle, they pass on their magic Saiga weapons to Beet, making him the strongest Buster ever. But Beet won't just fight the Vandels--he wants to destroy them and finally end the Century of Darkness. 
New Friends, New Enemies 
Still in the Black Horizon, Grineed's evil domain, Beet and Poala encounter Milfa, a Broad Buster, who arrests criminal Vandel Busters. Milfa recognizes Beet as Zenon's brother and becomes very friendly with him--much to Poala's dismay! 
But there's no time romance in the Black Horizon. Beet must face off with Frausky, the living gun. Frausky's accusations wound as much as his bullets--he tells Beet that his friend Kissu is really working for Grineed. But when they fight the Vandel, Rozzgoat, Kissu offers to sacrifice himself for Beet... 
Who will survive the Black Horizon? And who can Beet really trust?
