ES members Éclair and Lumière once were involved in a battle to decide the fate of the galaxy. They prevailed and peace was restored to the galaxy. Now, several years later, the galaxy once again stands on the brink of chaos. This conflict will see the dawn of two new heroines; Ascoeur and Q-feuille.

Twenty-five years after Éclair and Lumière, (from the flagship Kiddy Grade series), rescued the galaxy from destruction's doorstep, the GTO (Galactic Trade Organization), created after the defeat of the GOTT (Galactic Organization of Trade and Tariffs), act on behalf of universal peace by combating criminal activity.

Their special ES division mirrored after the GOTT's ES (Encounter of Shadow-work) force, now includes publicly acknowledged ES member candidates. The series follows two such trainees, Ascoeur and Q-feuille, as they work their way to ES membership.
