Demon Ranking System (鬼の序列 Omi No Jorestsu) is a system used to determine a demon's strength among all demons in the Demon World, or mainly among their peers inside the Babylus Academy. They can do this by proving themselves in tests designed to assess their strength, perform feats or gain accomplishments.


The Demon Ranking System classifies a demon's status in the demon world. Presumably, they start their ranking when they first go to a demon school, increase and/or decrease it through school activities, and even after they graduate, they keep their rank and may be able to increase it quite further.

Usage in School

A ranking owl.

All starting students are unranked, and has specific non-ranking state 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[1]. After, they are then classified by a ranking owl. The ranking owl has a pouch on its stomach that contents the ranking badges, of which each students are required to put their hands in and grab their base respective ranks. Most of the time, first years are categorized into Aleph and Bet rankings.[2]

Notably, 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, such as having narrow details to order then having a huge variations to pick for food. Though, all of the food are free for all students.[3]

Rise or Fall Ranking

A rise in rank can be granted to the students of Barbirus by the principal, Lord Sullivan, or any authorized Babylus 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.

Demons who reach the top rank, Yod, are considered as candidates to become the Demon Lord. Three such candidates currently exist.
