─── It was a long time ago.

Once upon a time, there was a kingdom called Lilias, a place fairly well-known in the human world.

As it was a kingdom, there were naturally those who would inherit the throne or those who would assist the heir.

However, one day, that person—still a young child at an age where they could not even make their own judgments—was

Taken away by someone.

The guards, sentries, and servants were supposed to have never taken their eyes off them. And yet, despite that, they were taken.

While the Queen and King struggled to calm the populace, having no time to wallow in their own grief over their beloved child, a single letter arrived.

"They are living happily in the Demon Realm"

It said.

By the time the Queen and King read the letter, Guest's thoughts had already been eroded by the monsters living in the Demon Realm.

It was the Four Great Sovereigns of the Demon Realm who kidnapped Guest. Strangely enough, they cared for and doted on Guest while acting as their butlers.

The Four Great Sovereigns: They hold the most power after the Demon King and effectively hold the right to rule.

It seems that monsters can transform into human form if they are of high rank, hold an important role, or possess equivalent power...
