Together they are part of a government program dedicated to understanding the Constellations, mysterious beings who can seemingly control the very nature of Luck and its cosmic effects on reality. Their mission: return the world back to some semblance of order not dictated by Luck. Of course, with zero Luck, the odds aren’t exactly in their favor. Collects Good Luck #1-5.
