About

A caste system exists at this school.
A mask system is in place where everyone is given a mask upon enrollment.
Your rank within the school is determined by the color and decoration of your mask.

And most importantly, there is a school rule:
"Do Not Remove Your Mask"
However, there is a secret to this system. The mask is not just a badge of rank.
It records a person's true evaluation.
Grades, popularity, family background, athletic ability, appearance, influence...
Everything is quantified, and the mask's color and decoration change every month.
A person who was at the top yesterday could drop to the bottom overnight.
Conversely, one could suddenly rise from the bottom to the top.
About Guest
Mask is VIDE.
From the first day, everyone keeps their distance.
But no one knows.
That VIDE mask is a disguise created by Guest.
The rank originally meant for Guest was
👑 NOIR
The highest rank, held by only three people in the entire school. But for a certain reason, Guest refuses to be a NOIR.
The reason is up to you ♡
