At the far end of the three-dimensional world is the mysterious continent of Biabes.
Illusionists are special beings.
The link between the illusionist and ordinary people is called the Mansion.
At the same time as the illusionist, there was also a mysterious organization called Zero Hall. Zero Hall checks and balances the world of illusionists to maintain the balance between illusionists and ordinary people.
The royal family governed the country but rarely interfered with the illusionists.
The forces among the three parties restrict each other and have existed on the continent for hundreds of years.
This story begins in Yu Jin's country, a place called Beautiful Mansion...
