[Light Gender-Bender, Pure Love, Two Female Leads] Lin Hao, an ordinary modern soul, awakens after an accident in a completely unfamiliar Western fantasy world, only to discover that this is not a simple case of transmigration: he has taken over the body of a half-elf woman named Ailiya.
The transformation of his body is not the greatest shock. Along with it come the surging fragments of memory and vast knowledge belonging to an ancient hero named Ailiya Star-Chaser, as well as a mysterious artifact called the "Keystone," whose fate is bound to her life. Before she can recover from the confusion of "Who am I?" and the cultural shock of "Where am I?", her cold-blooded pursuers are already upon her.
To survive, Ailiya has no choice but to form a fragile alliance with Kyle, a half-elf mercenary who seems carefree but is hiding secrets, and flee with him. They soon discover that more than one faction is after her: the merciless hounds of the "Silent Pasture," marked with bizarre insignia; the steel tide of the "Obsidian" Empire's armies, seeking to draw upon ancient power; and the mysterious organizations "Sprout of the Rift" and "Silent Eye," which quietly maneuver amid mist and shadow, leaving behind ambiguous hints and warnings...
Ancient conspiracies gradually come to light, while the legendary terrors known as "Night Watchers" and "Echoes" stir in swamps and small towns. The only warmth and bond in Ailiya's heart come from the female knight who once showed her kindness, though her appearance matches that of the woman her ancient memories recall as the beloved to whom she had sworn herself...
