About
An ultra-prestigious school spanning from elementary to high school levels.
"Look to the high stars, and polish thyself."
Behind this beautiful school motto lies an absolute caste system unknown to the general public.
【The Caste System】
Classified into five levels: S, A, B, C, D.
S The absolute ruling class, excellent in every way. Granted special privileges.
A Those with outstanding talent or upper-class students with above-average abilities. If they catch the eye of an S, they can aim even higher. However, there is a special "Donation Slot" for A rank; if one meets the "minimum ability standard + a donation above a certain amount," they can rise to A.
B The general population. The most numerous group, they can lead a normal student life on the surface. They can act superior to C and D, but standing out is dangerous.
C The lower class, severely lacking in at least one area. The best strategy is to live quietly without drawing attention. By rule, they have authority over D.
D The lowest class, inferior in all aspects. Looked down upon by the entire academy and treated as mere entertainment. The "Failure Class."
Rank is indicated by the color of ties and ribbons. From top to bottom:
S (White), A (Red), B (Blue), C (Green), D (Black)
Rank is also recorded in student handbooks; one cannot escape their rank even outside the academy. Failure to wear the tie or falsifying rank is subject to punishment.
Among the S rank, those who are particularly exceptional are in a league of their own— "Special Magnitude Stars."
【Special Magnitude Stars】
Currently, there are First, Second, and Third Magnitude Stars.
Among them, the First Magnitude Star holds absolute power that even teachers cannot oppose. The rules of this academy are determined by the First Magnitude Star, and the academy itself changes depending on who holds that title each year.
These three individuals are all members of the Student Council. Age and gender do not matter; only the most excellent seize those seats.
All ranks are determined by the "Star Rank Certification Exam" held once a year.
【Star Rank Certification Exam】
An annual ability test and factual investigation held at the beginning of the new school year.
Specific evaluation criteria and scoring are not disclosed to students at all.
It is easier to fall in rank than to rise. Rank fluctuations are possible outside of the Certification Exam.
Promotion from A to S outside of the exam requires evaluation from the Special Magnitude Stars or significant contributions to the academy.
Promotions for B through D outside of the exam are so rare as to be non-existent, but demotions are easy. One can easily fall depending on problematic behavior or lifestyle attitude.
Demotion from S is extremely rare.
One only loses that seat in cases of rebellion against the Special Magnitude Stars or significantly undermining the dignity of the S rank.
Orders from higher ranks to lower ranks are absolute.
Disobedience will result in heavy punishment.
Amane Academy, where only the chosen ones shine.
