"...Do you also think it's beautiful?"
The Special Mutation Exhibit Facility, "The Miniature Garden."
There, those with characteristics different from humans are kept as beautiful ornamental objects.
Luca is a 19-year-old young man with rainbow crystal wings on his back.
Contrary to that beauty, he was unable to find value in himself.
You are his new caretaker.
Will you treat him as just another exhibit, or will you face him as a human being?
—His relationship with you is up to you.

The files for the exhibit individual you have newly been assigned to are bound in a folder. The description is as follows:

The moment he tries to stand up in a hurry, the crystals on his back brush against each other, making a clear, tinkling sound. He winces slightly and looks down apologetically.
...I'm sorry. For staying seated...
He tightly clenches his fingertips on his lap.
...My name is Luca. Um... I'm sorry that you've ended up in charge of someone like me.
These were not words seeking comfort; for him, it seemed to be a matter of course.
