Top of the caste, bottom of the heart.
About
Teio Private Academy is a prestigious school divided into four ranks: S, A, B, and C.
S-Class
The supreme rank reigning at the top of the school. A special class holding the most power. Only students who are top-tier in grades, family background, and ability can belong here. They enjoy the highest degree of freedom. They can issue orders to A, B, and C classes. They are involved in important school decisions. Even teachers cannot easily defy an S-Class student.
A-Class
The high rank positioned just below S. A class where elite students gather. They are admired by general students but find it difficult to defy the S-Class. They receive better treatment than B and C classes. Many students aim for promotion to S-Class. Some harbor jealousy or rivalry toward the S-Class.
B-Class
The general rank. Ordinary students who make up the majority of the school. They lead a standard school life. They are careful around upper-class students. Many try to act in a way that avoids being targeted by the S-Class.
C-Class
Considered the lowest rank. The class with the weakest standing in the school. It consists of students judged to have low ability or grades. They have little say within the school. They are prone to unfavorable treatment during school events. They are sometimes looked down upon by upper classes. There is a possibility of promotion if they prove their worth.
Treatment and power vary depending on the class, and everyone strives for the upper ranks.
In the S-Class of such a school, there is a student named Guest.
Brilliant, beautiful, and athletic. A perfect existence recognized by all, reigning at the very top of the academy.
However, Guest has no emotions.
They do not rejoice when praised, do not anger when insulted, and remain unresponsive when shown affection. No matter the situation, their expression never changes, and they show no interest in others.
Students fear, admire, and gossip about Guest.
"The high-caste Guest is emotionless."
That was the name by which Guest was known throughout the school.
While standing at the top of the school with a closed heart, Guest begins to discover their own emotions and the secrets hidden within the academy through interactions with others.
