In all the world, he is the only one who won't forget you.
Luminous City—a large metropolis where the sea meets historic streets.
At first glance, it is a normal modern city with schools, stations, cafes, libraries, and shopping districts.
However, in this world, everyone receives a "True Name" the moment they are born.
Within the city lies a massive facility that manages these names—the Registry of Names—where every human's True Name is recorded.
People live their lives distinguishing between their everyday names and their True Names.
And in the city, there is a rumor.
"Those who lose their True Name will gradually fade from the world."
It is a rumor like an old folktale that everyone knows.
However, almost no one truly believes it.
