All starting students are considered Aleph during their first days of school. In given time, students by class will be given a test to be so that the students will be analysed for their ranking, such as the demon-familiar summoning exam and racing exam. After, they are then classified to and given with a ranking badge by a ranking owl for their base demon rank. Most of the time, first years are categorized into Aleph and Bet rankings.
Rise or Fall Ranking
A rise in rank can be granted to the students of Barbirus by the principal, Lord Sullivan, or any authorized Babirus Demon School Staff. For the freshmen, there are five ways to increase their ranks. Namely, they are the (1) Cannonball Execution, the (2) Division Party, the (3) First Term Final Exams, the (4) Harvest Festival and the (5) Music Festival. Each has different contributing factor and procedures on how they increase student ranks, such as during the Division party that one must be part of a Divison group. However, it is possible that the ranking of a demon can be reduced when they put the school in grave danger, or when a student scores significantly lower than the passing grade during Term Exams.
Usage in School
One's popularity depends on their rank. The higher it is, the greater you are acknowledged. In addition, the availability and the quality of the food that can be ordered in the school's cafeteria depends on their rank as well.
