Far in the future, humanity has moved into the skies and colonized numerous planets across the universe. To maintain order, an agency called the Galactic Organization of Trade and Tariffs (GOTT) has been established. Inside GOTT, a covert team of enhanced humans—the ES Unit—executes secret missions to halt major galactic crimes. Two such agents are the lowly C-ranked Éclair and Lumière. Although they sit at the bottom of the hierarchy, the pair possess formidable abilities: Éclair has superhuman strength and a lipstick whip, while Lumière can take control of any computer. Together, they are capable of handling any mission GOTT assigns them. However, as they complete more missions, the duo starts to uncover a massive conspiracy that causes them to question everything they know about themselves and the entire galaxy.
