The narrative centers on two young agents, Éclair and Lumiere, who are part of GOTT's ES (Encounter of Shadow-work) division, tasked with handling covert operations and maintaining galactic stability.

Éclair is a confident and skilled operative with a strong sense of justice, while Lumiere is more reserved and analytical, often providing the technical expertise needed for their missions.

The series also introduces key figures within GOTT, including their superiors and fellow agents, who play significant roles in shaping their development.

Themes of loyalty, duty, and the ethical dilemmas of enforcing justice in a vast and diverse galaxy are woven throughout the narrative. The dynamic between Éclair and Lumiere is central to the story, emphasizing their growth as individuals and as a team.
