Saeko Misaki

A widow, Saeko works as a researcher at the Toto Bio-Medical Laboratory and a part time biology professor at a university. Her full name is Saeko Nishiwaki Misaki. After her daughter, Hitomi, dies from cancer, Saeko becomes obsessed with her loss to the point that she cultivates Hitomi's cancerous cells into a biological mutant creature named Wasted 13 in the Toto Bio-Medical Laboratory. Saeko commits suicide after seeing the monster she considers to be her daughter killed by Flamethrower-wielding JGSDF soldiers of the Chemical Weapons Division. Hata grabs her hand to try to save her from falling to her death but he loses his grip due to the rain.
