After Kei Kishimoto failed to get good grades, her mother stated she was worthless, and shifted all of her attention towards Shiori. This led to Kei's suicide attempt.
Shiori is first seen when she enters her house after a cloned Kei hangs the phone (which was originally intended for Shiori). She is seen later, this time talking to her mother who informs her of her sister's suicide attempt. Having just seeing her sister, Shiori is confused and tells her mother that Kei is in the house, causing the cloned Kei to quickly leave the house.
In the back of Gantz volume 9, she is quoted as saying:
"My sister is the overachiever, so I can just sit back and do nothing. But its hard for her. Our parents focused their entire expectations on her, and it drove her to try suicide. We didn't get along very well before then, but I started to feel sorry for her. Maybe it was all for the good because it helped bring our family together."

Haruka Nemoto was the wife of Tetsuo Nemoto. Sometime ago, she and Tetsuo were married and had a son they named Eikichi. Unfortunately, her breasts couldn't produce milk - meaning she couldn't breastfeed her son. Tetsuo than had to go to the store every night to get milk for his son. Although she can't breastfeed, when Tetsuo comes home from the store one night he somewhat rapes his wife and the next morning it shows her unconscious naked body being suckled on her son. The night her husband dies, she opens her shirt and tries a vain attempt to feed her son she notices a white fluid leaking out her nipple - milk - and is overjoyed.
