He was supposed to die: this was a fact that Gabriel knew well. But then suddenly he was trapped in an unwilling vessel. An experiment of the Galra combining angel and soul, Gabriel and Lance must find a way to survive the arena until they find out how to escape. That's easier said than done when they're miles from Earth and spend most days with their minds combined into one.

When Gabriel encounters a little boy that can see him despite of him being invisible, he doesn't think too much of it. But when he follows the boy home out of curiosity, he unveils some secrets that weren't meant to be revealed.
