[This chapter introduces the world and how it works. It may contain light spoilers, but don't skip it]
This world is called Earth—a blue planet filled with life. Humans, animals, insects... and Devils. Yes, Devils.
Long ago, people believed that Angels once existed too—beings who stood against the Devils. But no one's ever seen them. Maybe they were just myths. Or maybe… they were wiped out.
Anyway, where there is life, there is also death. In this world, Devils are known as the Call of Death. They've existed since ancient times. They look nearly human, but don't be fooled—they're far stronger, both physically and magically.
Oh yeah—magic.
In this world, magic was born alongside living beings. Both humans and Devils can use it. Devils wield it for destruction. Humans… well, they use it for both healing and killing.
But nowadays, all of this sounds like fantasy. Talk about Devils, Angels, and magic, and people will either laugh or label you insane. These things are seen only in anime, manga, or fairy tales.
Yet the truth is… those fairy tales are far more real than people think.
«Explanation»
Only certain humans—those with magical blood—can sense and see and feel Devils. In ancient times, a massive war broke out between humans and Devils. No one knows who won. All that's known is that both sides survived.
Over time, fewer people could use magic, and Devils stopped appearing in public. So, the world moved on, thinking the age of magic had ended.
But they were wrong.
Devils never left. They simply began killing in secret—especially at night. While a few humans continued to fight, most gave up. Magic slowly began to vanish. Still, even after 2,000 years, some managed to preserve it.
«Magic Explanation»
Magic in this world is known as "Styles", and those who use them are called Stylers.
There are five major elemental Styles-
♦ Solar Style
♦ Aqua Style
♦ Gust Style
♦ Nature Style
♦ Lightning Style
But with enough mana and magical knowledge, some can develop variant or Unique Styles—custom magic types no one else possesses.
The more mana you have, the more powerful and long-lasting your Styles become. Some are born with high mana. Others must train hard to increase it.
To learn a Style, a person must meet these three conditions-
1. Be at least 18 years old
2. Have an IQ of 111 or higher
3. Carry the blood of your incestors who were Stylers in past—magic must run in your family line
If you qualify, you enter intense training. Not everyone survives it. And even if you do, the Elders decide if you're worthy to become an official Styler.
Once accepted, you're ranked based on your skill. The 6 Styler Ranks are
6. SR-E (lowest)
5. SR-D
4. SR-C
3. SR-B
2. SR-A
1. SR-S (highest)
Your rank determines the missions you'll face—especially since Devils are ranked too.
«Devil Classification»
Devils follow a strict hierarchy given by the Devil Lord
1. No Rankers – Mindless creatures. Weakest of all.
2. Matures – Can think, plan, and fight like humans.
3. Low Crown Devils – Only 5 exist. Serve directly under the Devil Lord. Ranked from 5 (weakest) to 1 (strongest).
4. High Crown Devils – Elite Devils. Also limited to 5, ranked from 5 to 1. They carry out the Devil Lord's will.
«The Pure White»
There's one strange phenomenon known only to Devils and Stylers—The Pure White.
When a Styler and Devil encounter each other, everything around them freezes. Time stops. All other living beings vanish. In this state, only the Styler and the Devil exist. It feels like the world turns pure white.
The Pure White ends when one of them dies. Everything then returns to normal. Nothing that happens inside this state affects the outside world.
In modern day the year is 2025.
The world seems peaceful, but behind the curtain, humans and Devils continue their battle for survival.
This is a world filled with both
Death and Living.
