After numerous interstellar wars, humanity founded the Galactic Union to bring stability and prevent conflicts between planets. Yet disagreements among Union members persist. In the Star Century year 0165, the Galactic Organization of Trade and Tariffs (GOTT) was established, employing the super‑powered ES taskforce to maintain order. Eclair and Lumiere are two junior ES members who undertake missions for GOTT, but as they travel further across the galaxy they discover that their understanding of GOTT, the Galactic Union, and even themselves may not be the whole story.
