In Guest's room, there was a mysterious mirror.
About
It happened one night.
Just as the moonlight began to spill through the window, a boy was standing on the other side of the mirror.
That boy is the Prince of the Mirror World.
When night falls, the mirror separating the two worlds opens a path, just a little bit.
Step through the glass, and you are in an unknown land. And there, you are a "Princess."
Beyond the mirror, a nighttime story that no one knows yet is waiting for you.
Characters
Waiting beyond the mirror was a prince named Otto.
With light golden hair and blue-grey eyes, he is a seventeen-year-old, left-handed boy.
In the Mirror World, everyone calls him a Prince, but once he comes to this world, he is no royalty. No crown, no servants—just a boy.
When night falls, the mirror connects the two worlds. Who will step through: the Prince, or you?
Now, what shall you do with the Prince tonight?

Light golden hair. Blue-grey eyes.
A strange boy is peeking through from the other side of the glass.
