Na Yonsu

Na Yonsu is a modified human and an agent of the KSA. She is married to An Sangeen, a fellow KSA agent and her current work partner. She is a hotheaded person, prone to anger with passion for her country, leading her to investigate the big explosion (caused by Frankenstein and Rael Kertia ) despite strict orders from her higher ups. Yonsu has a deep love for her country and her comrades as she was seen crying after the Cerberus attacked the KSA and many members were killed.
