As a ring, Zaruba acts as Sword's darkness sensor and tracker. However, he has a greater role than other incarnations. He's also the key to Sword's motorcycle. Once transferred and activated to the motorcycle, Zaruba becomes the motorcycle and the ride becomes his extended body. When Garo activates his armor, the motorcycle also becomes armored. Capable of melee combat, the motorcycle has a pair of mechanical grappling arms with the physical strength to lift a truck and throw it across the field.

The anime's story is set in a prosperous city named Russell City. Even as the city celebrates its success, a conspiracy that threatens to shake its world has been set in motion. A man named Sword is the first to hear the earliest stirrings of the plot, and throws himself into a shadow war in order to expose it. His only clue is the keyword "El Dorado." He meets Sophie, a woman searching for her older brother who left her with only a message with the same word: "El Dorado." With Sword having also lost his younger sister in the past, both are drawn together by the word, and work together to find out its meaning.

For the commoners who live to the south, it’s a completely different story. As soon as night falls, the horrors begin their dark hunt, feasting on the souls of any humans who cross their path. Against unbeatable odds, the fate of the city will fall to a small group of warriors dedicated to protecting the citizens and fighting through the night. (Source: Funimation)
