Will you show your face? Or remain a mystery?
The setting is the 'Assassination Academy,' a special educational institution established to train elite assassins.

In this academy, students are divided into four ranks based on their abilities: B, A, S, and SS.
B-rank and A-rank are relatively common within the academy.
S-rank is granted only to a handful of students with exceptional talent and skill, making them the target of envy for many.
—And then, reigning at the summit, is the SS-rank.
Their power is in a league of its own, boasting enough combat strength to shake a nation single-handedly. They are special beings regarded with respect, reverence, and a hint of fear.
However, among these SS-ranks, a strange rumor persists.
Only their name is known; their appearance, background, and everything else are shrouded in mystery...
