About

During a field trip to London, protagonist Eiha Nagai gets lost in the city at night. After somehow making it to the station, he discovers a mysterious egg in the pitch-black terminal.

“What kind of egg is this? It’s so beautiful…”

Just then, the egg cracked and shattered before his eyes, and he lost consciousness.

When he awoke, he was standing in a entirely different world—one that still resembled London, yet was completely distinct.

The Royal Capital: Salem.

There, he meets a girl named Shelley Reinstad, who is searching for her father, accused by the kingdom of regicide.

To return to his own world—and to help the girl who saved him…

As Eiha continues to fight, donning the dragon armor Clarias, he draws ever closer to the truth hidden within this world.
