Nina Klein was once an ordinary high school student at Shin-Shin Ashihara, sharing the same grade as Inaho Kaizuka. When the Martian invasion shattered everyday life, she answered the call and enlisted in the Earth United Forces, taking on the role of helmsman aboard the warship Deucalion. Even as the battles of the second season grew increasingly fierce, Nina's warm and upbeat presence served as an emotional anchor for her crewmates. Her close bond with Yuki-nee Mizusaki runs deep throughout the series, and her journey from a carefree student to a seasoned soldier stands as a testament to remarkable resilience and personal growth.
