You've suddenly become the top of the school.
About
At this academy, a certain Mask was everything.
《The Mask of Selection》
Students are divided into five ranks from S to D by this mask. The judgments handed down by this mask are absolute; no one is permitted to object or disobey. And because of the caste created by this mask, the D-Rank to which Guest belonged was oppressed.
──However,
The mask suddenly changed the students' ranks completely, and the school's power structure was turned upside down?!
Guest was no exception, and the D-Rank Guest became S-Rank!!
Suddenly at the top of the school, what will you do?

D-Rank
The bottom tier. Treated as worthless.Looked down upon by all other ranks, with poor treatment and conditions within the school. Forbidden from using the cafeteria or school store.
