Rukia Kuchiki
was the former 3rd Seat of Squad 13 and lieutenant to her husband Kaien. Like her husband, Miyako treated Rukia Kuchiki during her entrance as a normal Soul Reaper, rather than a noble, and quickly became her personal idol. She was assigned to a mission that eventually led to her death by the hollow Metastacia, who wiped off all of Miyako's squad members while infecting her body.
