Following the valiant deeds of Éclair and Lumière in the first installment of Kiddy Grade, wherein they thwarted a threatening catastrophe looming over the galaxy, the Galactic Trade Organization (GTO) arose to maintain order in the universe by opposing unlawful conduct. GTO established a specialized ES unit, much like the one managed earlier by the vanquished Galactic Organization of Trade and Tariffs (GOTT), that now welcomes trainees aspiring to join the ranks of acknowledged ES agents. This show details the endeavors of two such trainees, Ascoeur and Q-feuille, as they strive to earn their stripes as ES personnel.
