|Title||Student / Housewife|
|Voiced by||Naomi Horikawa|
Noriko was the sole survivor of the Bright Win incident. She was impregnated by her boyfriend Ichiro Nakajima at the age of 14.
Ichiro was gone 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 2 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 (Mother's avatar) has entered her daughters, and therefore cannot recognize Ryuko Tagawa as her own child.
Both her surname (Kifune 木船 - Wooden Boat) and Ichiro Nakajima's surname (Nakajima 中島 - Central Island) are puns for Yamijima Island and the Bright Wing Ferry respectively.
