Yuki Kaizuka

Yuki Kaizuka is the older sister of Inaho Kaizuka and a warrant officer serving in the United Earth military. After losing both parents at a young age, she single-handedly raised her younger brother, shouldering responsibilities far beyond her years. While she openly struggles with household chores and often relies on Inaho to keep their home in order, the battlefield reveals an entirely different side of her — a disciplined, dependable Kataphrakt pilot who leads with conviction. Naturally upbeat and unafraid to wear her heart on her sleeve, Yuki commands the Mustang Squad when war breaks out between Earth and Vers, guiding her brother and a group of students through the chaos of an interplanetary conflict.
