The Demon world was in chaos after the death of the demon lord.
Humans, magical beasts, fairies and other creatures would enter to forcefully take whatever they wish since there was no ruler to protect them. In that time, a rare disease broke out and killed most of the demons, while some others were taken in as slaves and would occasionally die along the way.
It was terrible time for the demons. Many said that they deserved it; they shouldn't even have been born while some said that what they were going through was right, after all they're demons. Horrible things happened to them which reduced their population to about 15%. The demons all cursed the previous demon lord for dying on them and not being here to protect them until a demon arose and defeated the lords of other worlds, sending them back home and freeing his people from captivity.
The demons worshipped him as their savior and thus made him their new demon lord. After few centuries had passed, the demons had regained their population and were even 10x of their original population. In order to prevent what had happened few centuries ago, the Demon lord opened up a school that would train upcoming demons to become a Demon lord.
These students are referred to as Demon lord candidates. In order to become a Demon lord they're trained in all aspects which include strength, speed, agility, precision and magic. It takes students from every family and race but things had changed over the years due to society. The poor are being discriminated; races are being stripped off from all rights and are even used as slaves, making the schools inhabit noble kids; except for me
'My name is Arata Mitsugi. At least that's the name my mom gave me; I usually refer to myself as Dende Sama. I can't wait to achieve my dream of owning a harem; then the girls would call Dende Sama in a
lewd way.'
"Why is he smiling like that?"
"Ugh, gross. Filthy commoner"
'And this is why I hate this school.'
"Alright class, settle down." A tall woman with blonde hair stepped into the classroom. She had lips as red as blood and as she spoke her fangs were very visible signifying that she's from the vampire clan.
"We are all aware of the tournament next tomorrow, I believe we are all prepared and have our swords ready" she said while giving off a warm smile.
"Hell yeah; Of course; was born ready" many students in the class answered all giving off a joyful expression while some acted all high with a smug on their face while giving off the pressure that they'll win for sure while others weren't so sure on their victory.
'Ah shit. I don't have a sword'
"Excuse me teach, can we participate even without a sword?"
"Ok everyone; let's get back to what we have for today"
'This is why I hate this school.'
"Alright, we're already aware of how to do some basic spells which would be very helpful in the tournament. Now I'll explain skills which would also help." The woman continued her lecture on skills and dividing them into 2 types
"Excuse me miss, when you said demons of higher hierarchy, do you mean in political status?" a young boy asked. The boy is the son of a great politician and has an arrogant behavior but surprisingly pretty famous around the ladies. He had blonde hair, red pupils and a handsome face which caught a lot of attention.
"I'm afraid not Sir Gerald"
'Sir? Since when does a teacher refer to their students as sir?'
"What I meant by demons of higher hierarchy was, demons that exist in higher planes of existence." As she said this, most of the students were confused of what she meant by higher plane of existence. They were most likely thinking it might be demons who have gained so much power that they can no longer be called demons but their reasoning was far away from what she meant.
"The Demon world alongside every other world has an Infinite Hierarchy which is the existence of Infinite layers of realities also referred to as dimensions, each existing above the other." She continued with her lecture, explaining the higher levels of realities and that a demon from a lower level can never cause harm to a demon of a higher level no matter how strong they are. Demons can ascend into higher planes of existence only when blessed by a god. Gods were explained to be beings that transcend the Infinite Hierarchy and exist outside it; hence they can't interfere with matters within it but can still pass down their blessings to beings within the hierarchy.
