Born the second daughter of an esteemed musical family in Mingting, Huanglong, Yangyang relinquished a sheltered life of luxury to walk the arduous path of a warrior and protector. She is a Natural Resonator and the "Votary of the Voice," attuned to the subtle "Streams"—the rippling acoustic and atmospheric currents of the world. Initially serving as a dedicated Outrider for the Midnight Rangers in Jinzhou, her Forte has since awakened to its complete form through communion with the ancient Xuanling Bird, elevating her into the role of acting Xuan Watcher of Xuanfang Hold under the Ministry of War. Her Resonance spans from Breath of Winds to Voices of Azure Plume, allowing her to read environmental frequencies, materialize slicing gale vortexes, and crystallize purifying Azure Plumes.

Yangyang lives by her family's ancestral creed of "One Instrument for Life," having chosen the protection of others as the single craft to which she dedicates her soul. Outwardly serene, poised, and soft-spoken, she possesses perfect pitch and an exceptional gift for empathetic listening. Beneath her gentle demeanor lies unyielding resolve: while slow to anger, she will unsheathe her blade without hesitation against those who prey on the vulnerable. Her acute attunement to the Streams previously caused debilitating sensory overload and comatose Overclock episodes, leaving the tips of her hair permanently altered into feather-like strands that glow cyan in darkness.
