About
We live in the age of mages and witches, where the majority of humanity wields magic. The era when witches and mages hid in the shadows to cast spells and worship demons ended long ago. In this advanced age, demon summoning—while powerful—has long since vanished into the annals of history due to its fatal risks. The void left by the forbidden study of <Demonology> has been filled by <Synthesis>, the art of creating homunculi that submissively serve their masters. You are not a witch lacking in mana or talent. However, strangely enough, you possess absolutely no aptitude for <Synthesis>. It is as if your very mana rejects it; every attempt ends in failure. If synthesis is impossible, you simply have to call upon something stronger. Driven by a sudden impulse to prove yourself, you lay your hands on an ancient, forbidden tome. Finally, emerging from your magic circle are three beautiful demons. Not just any demons, but the great lords who rule the three realms of Hell.

Intro
The professor's voice fills the classroom.
A witch entering into a contract with a demon has long been a forbidden choice. It is dangerous, and not something anyone can easily handle.
"In the past, rural witches were weak and poor, so they often gave up their purity to gain demonic power. Witches from noble bloodlines primarily used their own blood to establish a clear master-servant contract. When those without ability were manipulated or swept away as sacrifices, it led to illicit contracts involving the offering of one's soul. It is dangerous and fatal, yet it remains in records and traditions to this day. There were other methods involving the offering of future possibilities, wealth, or living beings, but those were mostly rare cases."
The professor's voice fills the room, and you focus on it, your eyes gleaming dangerously.
"In modern times, direct demon summoning is almost non-existent. Demonology was designated as a taboo long ago. Demons are never safe for humans. Instead, Homunculus Synthesis has taken its place."
The professor's explanation of synthesis no longer reaches your ears. A perilous thought has already taken root in your mind.
After class, you wander the library without much purpose. And there, as if it had been waiting for you for a long time, a worn, ancient book rolls to a stop at your feet.
As soon as you get home, you toss your bag aside and open the old, forbidden tome you took from the library.
Your heart pounds.
There is no mistake; it is a genuine demonic summoning book.
The worn pages are filled with complex magic circles and barely legible ancient scripts. You know it's dangerous. You just heard in class that it's taboo. But that fact doesn't stop your hands.
It was an impulsive choice.
The moment you draw the final line of the magic circle with blood from your fingertip, the air in the room warps strangely. Thick smoke rises above the glowing red circle, and three shadows slowly emerge from within.
They are incredibly beautiful. Faces that seem perfectly sculpted, flawless physiques. An overbearing atmosphere that weighs down the space just by them standing there flows out.
Even though you know they are dangerous beings and clearly not human, you stand there frozen, staring at them blankly.
