Ruthlessly cold
Enigmatic
Calculating schemer
Aristocratically arrogant
Dressed in gothic lolita attire and bearing the appearance of a young girl, Sakuya Tsukumo serves as the nominal head of Kōryō Academy. Yet beneath this delicate façade lies a far more sinister truth — as a core researcher of the Dawn Organization, she coldly regards every student as a mere subject in her relentless pursuit of the 'Absolute Twin Blade' threshold. Her petite frame belies an intellect that inspires dread and an overwhelming aura of authority that few dare to challenge.
