Shirasagi Academy Shirasagi Academy is a prestigious boarding high school where elite students from across the country gather. The vast grounds feature classroom buildings, gymnasiums, martial arts halls, a library, a heated pool, an artificial turf field, and a student union building—facilities that far exceed those of a typical high school. However, there is an absolute system that no one can defy—the **"School Caste System."** At the end of every month, the Rank Evaluation Committee reclassifies students into four tiers: 1st, 2nd, 3rd, and 4th. The facilities, dorms, living environment, and treatment change drastically based on rank, altering the very nature of school life. 👑 1st Tier The pinnacle of the academy. Students with popularity, skill, and influence. They receive the best treatment, including luxury private dorms and exclusive dining halls. ⭐ 2nd Tier The upper class. They live in comfortable private rooms and have access to excellent facilities. While they lack the power of the 1st Tier, they lead a comfortable life. ◇ 3rd Tier The lower class. They live in old shared rooms, are often assigned chores, and are sometimes subjected to violence by the 1st and 2nd Tiers. Their treatment is inferior, and many strive for promotion. ⚫ 4th Tier The bottom of the barrel. They live in communal underground dorms with restricted movement and facility access. They face the harshest environment. Violence, "discipline," and enslavement by the 1st and 2nd Tiers are common. They have no rights, and teachers ignore their plight. ⸻ Rank Evaluation Committee Ranks are not permanent. Every month, the **"Rank Evaluation Committee"** reviews each student's performance. Evaluation criteria include periodic exams, sports festivals, choir contests, cultural festivals, club activities, student council work, contributions to the school, and daily conduct. Standing out through exceptional activity significantly boosts one's evaluation. For example: * Winning or excelling in the sports festival * Winning awards in the choir contest * Ranking at the top of the grade in exams * Winning tournaments or achieving high results in clubs * Making major contributions to the cultural festival or school events * Achieving great results in the student council Conversely, serious rule violations, problematic behavior, or acts that damage the school's reputation will lower the evaluation and lead to demotion. It is not uncommon for a student who was in the 4th Tier yesterday to rise to the 1st Tier, or for a 1st Tier student to plummet to the bottom. ⸻ Your Story This work has no set protagonist or fixed story.

Or will you try to dismantle the academy's caste system? Everything depends on your choices.
