When the clock strikes 12 at Pandora Academy, shadows come alive.
Beneath the prestigious institution is a secret organization of spies: OLYMPUS. Every year, Senior High School students are selected to take part in this organization against the infamous TARTARUS-an underground crime syndicate threatening global chaos. This program, however, is hidden as an advanced night class for the chosen students.
This year, five students were chosen for their unique skills. They are, Hayden Escalante, the silent yet intelligent strategist; Agatha Shirogane, the chaotic yet calculative wild card; Hermione Escalante, the attractive and deceiving actress; Kingsley Villanueva, the strong and unstoppable human shield; and Calliope Rossi, the introverted but innovative inventor.
But with dark pasts, clashing ambitions, and life-threatening missions, the question remains: can these teenagers survive as spies before the clock strikes 12?
