The story takes place in the fictional country of Merya.
It is an era of booming industrial development.
Electricity is widespread, factory assembly lines roar around the clock.
Stock codes scroll ceaselessly on towering billboards, and city center streets are packed with cars...
Yet no one notices that the glass-clad skyscrapers cast shadows large enough to engulf the entire city.
Grey is an ordinary young man living in a rural town.
At the invitation of a fellow townsman, he traveled to the capital, Rivera, to participate in a months-long study exchange program.
However, on his very first night in Rivera, he had a strange dream.
In the dream, a group of people wearing eerie masks seemed to be plotting an assassination attempt on the king...
– The next day, news broke that the king was indeed attacked.
Should Grey use the information he had to help those who were innocently harmed?
Or should he stay out of trouble and keep his distance?
And most importantly—was what he saw that night truly just a dream?
