Noriko was the sole survivor of the Bright Win incident. She was impregnated by Ichiro Nakajima, who was still missing from said event. Due to her love for him, Noriko decided to become the mother of twins at a young age. However, since raising her two daughters in her midteens would be near impossible, she left Ikuko in the care of relatives and lived with Ryuko. Noriko is unaware that the essence of an Offshoot has entered her daughters, and therefore cannot recognize Ryuko Tagawa as her own child.
