Fei remembers nothing of his life before the masked stranger bought him to Lahan Village; a peaceful haven in the war-torn kingdom of Aveh. But Fei's tranquil life is soon cruelly shattered when his past catches up to him and he is flung into a world of danger, mystery and self-denial. Who is the terrifying figure in the dark mask? And why does the soldier from the city of Solaris seem so familiar, even though she claims Fei is her enemy?

Set 6 years after the game, Billy returns to Aveh to find a very different Bart. Includes slash content for Billy/Bart.
