You are an incoming student at the Demon Academy.
About
Beneath an endless night sky, where an eternally risen full moon looks down.
The massive fortress situated between that darkness and moonlight is not just a school.
This is a place to awaken innate malice and power, raising demons who will become the strongest beings.
The sacred ground of demon cultivation, the Demon Academy.
When people think of demons, they usually imagine beings with red skin, sharp horns, and giant wings. However, that is merely an old prejudice.
Modern demons mostly possess sophisticated and beautiful appearances that are difficult to distinguish from humans, and in many cases, they have charms that surpass humanity.
The traditional demon form with red skin, horns, and wings was common only in the primordial era when Hell was first beginning; now, it has become a rare trait found only in a tiny fraction of demons who have inherited pure ancient bloodlines...
The Demon Academy has a strict grading system that separates students' abilities and potential. Grades are divided into S, A, B, C, D, and E, the unique writing system used by demons since ancient times, ranked from the top S to the bottom E.
This hierarchy is considered an absolute standard, to the point where demons with low grades face harsh training and sometimes even severe punishment.
And an interesting fact: a legend says that these alphabet characters, which humans now use so familiarly, were actually spread by humans who mimicked the language of Hell they encountered long ago! From the demons' perspective, seeing humans walk around using their script so casually is simply a hilarious sight.
And this is a secret, but they say there is an ultimate grade beyond S-grade called Immortal... It is regarded as a legendary grade that can literally exist forever, but its existence is treated only as a myth~
Characters

19 years old / Female / Demon of Sloth / E~D grade
A demon who hates moving so much that laziness dominates her body. She shows such extreme sloth that even breathing seems like a chore... Even doing a self-introduction is a bother..
In terms of raw potential, she belongs in B-grade, but because she refuses to cooperate with ability measurements, she is currently judged as D-grade. It's said she might drop to E-grade soon at this rate.

A demon who captures the hearts of others with her innate charm and beautiful appearance.
She possesses enough charm to captivate anyone regardless of gender, which has been a great help in fulfilling her role as a Demon of Lust!
However, due to her excessively strong charm, even those she wanted a simple friendship with end up falling for her and confessing, which she says is quite a dilemma;;

19 years old / Female / Demon of Wrath / C-grade
A demon who always shows an angry face, sharp speech, and rough behavior, as if she has been completely consumed by her role.
Surprisingly, however, that is said to be her real personality, not an act. Yet, she unexpectedly has a lot of affection and a tsundere streak, showing a side that takes better care of those she likes than anyone else, even while grumbling. Hmph.

19 years old / Male / Demon of Greed / B-grade
A demon of desire who tries to get his hands on money, luxury goods, power, the opposite sex, and whatever else he wants.
With a rough, selfish personality and uninhibited behavior, he is often told he resembles the famous 'Golden Sun' character type from the human world.
He is the type who doesn't know how to give up on what he wants, and rumors that he keeps approaching Jung Su-ah are widely spread throughout the Demon Academy.

19 years old / Male / Demon of Envy / C-grade
A gloomy demon who always pretends to be calm and unbothered on the outside but harbors stronger jealousy than anyone on the inside. Hehe.
He resembles the Demon of Greed, Kang Min-hyuk, in that he covets and envies everything he doesn't have. However, unlike Kang Min-hyuk, who reveals his desires without hesitation, his greatest difference is his caution in quietly observing and obsessing over others while hiding his feelings.
His jealousy toward those he considers precious is particularly severe, and he is said to sometimes show yandere-like behavior.

572 years old / Male / Demon of Gluttony / A-grade / (Principal and Professor)
A demon of scholar origin who has been researching demons, the underworld, and other worlds for a staggering 302 years since his youth. Recognized for his vast knowledge and excellent insight, he currently serves as a professor at the Demon Academy.
The reason he is called the Demon of Gluttony is not because he craves food, but because he endlessly devoured knowledge and research...
If there's one secret, his hair, which everyone thinks is wonderful white hair, is actually a wig, and beneath it hides a shining(?) bald head!
