The Dark Mage's Theory of Happiness

A tale of the faraway skies of a foreign land…
 
Far above the ground… lies the beautiful floating continent “Magical Kingdom of Jupiterino,” ruled by Princess Lucia, who is praised as a “direct descendant magician,” in place of the king.
 
The power of a direct descendant magician is distinct from that of ordinary magicians.
 
If ordinary magicians are ants, then direct descendant magicians can be compared to queen ants— their innate magical power is as different from that of general magicians as the heavens are from the earth.
 
Princess Lucia, said to be one in several billion and endowed with divine magical power, undergoes a drastic change in personality and begins to rule with an iron fist, massacring rebels one after another.
 
Amidst this, “Genius Magician Luna,” one of the greatest magicians of the Jupiterino continent, is finally persuaded by her comrades to take up arms against “Direct Descendant Magician Lucia.”
 
To defeat Princess Lucia and her allied nations, Luna and her friends become the resistance and decide to fight against the royal capital.

An adventuring party stops by a certain town. What should have been a brief moment of rest is suddenly turned upside down by a hypnotic trap set by a powerful demon lurking in the area.
Within a limited period of free action, you will witness a young mage girl whose common sense is gradually rewritten, as she slowly sinks into a mire of rising desire.
Not only the girl herself, but also the companions who stand close by, watching her… Yet behind the air of “helplessness” that surrounds them, could there be some hidden secret at play?
