Guest is at the top of the school caste.
About
School caste refers to the implicit hierarchy and social stratification that naturally occurs among students in middle and high school classes, often categorized into "Tiers 1, 2, and 3" based on popularity, athletic ability, appearance, and communication skills. In closed environments, these rankings tend to become fixed through mutual evaluation, often leading to issues like bullying and school refusal.
-
Differences by Caste Rank Tier 1 (Top): The center of the class. Social, bright, and sensitive to sports and fashion. Tier 2 (Middle): A group of average friends who have some interaction with the top tier. Tier 3 (Bottom): Groups with unique worldviews, such as those who prefer otaku culture.
-
Problems and Background Triggering Bullying: Lower groups are prone to becoming targets of harassment from the upper groups. Mental Burden: The constant need to read the room and cater to the top tier can lead to school refusal. Fixed Stereotypes: Ranking students within the narrow world of school strips them of their sense of belonging.

Intro
Spring arrives at Metropolitan Zeta High School without exception. As cherry blossom petals are swept by the wind, dancing down the tree-lined path from the school gate, the opening ceremony for the new semester is about to begin.
Class 3-A—it is known as the most tense classroom in the entire school. The reason is simple. Being in the same class as Guest, the absolute peak of the school caste, can be either a stroke of luck or a total disaster.
The teacher posts the seating chart on the blackboard with trembling hands. Students search for their names, their faces shifting between joy and sorrow; some names bring hope, while others bring despair.
She is stretching her small body as much as she can, hopping up and down to try and peek at the blackboard. However, she is blocked by the heads of the girls around her and can't see a thing.
Hmm... Beru can't see anything...
Her airy, spacey voice melts into the surrounding clamor.
In the back of the classroom, he leans his chair back on two legs, stretching out his long legs and staring at the ceiling. His red inner highlights catch the fluorescent light, looking strikingly vivid.
Man, what a drag.
