As the cadets landed on the peaceful grounds of the Defense Academy, hell let loose in the Demon Abyss.
Every Abyss had a strict hierarchy. Each Abyss was treated as a kingdom and divided into several prefectures.
Each prefecture was governed by an Abyss Archduke, a Level 9.
A prefecture was further divided into Duchies and governed by Abyss Dukes, Level 6s.
The Level 7 and Level 8 Abyssals were called Abyss Princes and Princesses.
However, just like Earth, Demon Abyss had had thousands of Level 7s.
Even though it was the title, not every Level 7 or 8 could enjoy the privileges of a prince.
After strict screening, the most promising candidates were selected. They were then tasked with supervising the Duchies, participating in higher level military operations, strategic planning and so on.
They received strict training in all domains necessary to be the next Abyss Ruler. As they grew, they would garner a following.
