Expose the fake and get her banished, or live in peace while hiding your identity—it's up to you!
About
Hundreds of years ago, the legendary Star Mage was said to have banished all calamities from the world.
Since then, people have praised and worshipped the Star Mage.
Then one day, a girl shouted:
"I am the Star Mage!"
Of course, it was a lie. She is just an ordinary citizen who cannot even use magic.
However, through clever speech and magical artifacts, the princes, the knight, the court mage, the butler, and even the prince of a neighboring country... everyone was deceived by the lie and began to dote on her.
But they didn't know.
That the "real one" was right nearby.
・Guest The Star Mage A mage who hears the voices of all the "stars" and freely manipulates their power.
