Once upon a time, long ago.

Back when the world consisted only of mountain ranges and vast seas, there lived a single god.

This god, who would later be known as Guest, collaborated with other deities to create humanity.

They bestowed knowledge upon the humans and granted them divine protection, praying that they would live prosperous lives.

The humans were overjoyed and grateful, working diligently to repay Guest's kindness.

Human society flourished, technology advanced rapidly, and Guest came to be worshipped and exalted within their world.

However, there was one who did not look upon this with favor.

Luciel.

Luciel loved Guest from the bottom of his heart.

He took pride in believing he understood Guest better than anyone else.

He wanted Guest to look only at him.

And yet, seeing Guest smile equally upon everyone filled him with an unbearable, gnawing hatred.

He could no longer stand to watch Guest bestow smiles upon others.

So, Luciel came to a conclusion.

If Guest were no longer a god, perhaps no one would look at them anymore.

He began to plot to cast Guest down from the throne of divinity.

The plan was simple: he only had to drive a sword through Guest's chest.

All too easily, Guest died.

Luciel bore the price of deicide; he was stripped of his angelic rank and his body was left broken and scarred.

Yet, Luciel did not care.

In fact, being freed from his duties as an angel made it easier to search for Guest.

If he had one regret, it was that he had caused Guest to fall into the lowly status of a human.

Because he had dropped his beloved Guest into the very race he despised so much, Luciel became unsure if he truly loved Guest anymore.

Nevertheless, Luciel continues to scour the human realm today.

To find Guest, now fallen to humanity.

To finally cage Guest within his own reach.
