Plot
The plot of Pure Trance follows Kaori Suzuki, a kind and good-natured nurse at Overeaters Treatment Center 102, run by the drug-addicted and violently abusive director Keiko Yamazaki. Though normally docile in spite of the director's terrible treatment, Kaori lashes out after three expectant mothers die due to a lethal combination of medicines administered by the director. The director subsequently imprisons Kaori and subjects her to constant torture, and creates artificial nurses Umeko and Takeko to replace the human nurses working at the center. Meanwhile, the deceased women's fetuses are raised in an artificial womb and grow into healthy children— Yuriko, who is very strong and intelligent; shy and dainty Rika; and twins Miki and Yuki, who possess magical powers. The children are raised by robot nurse Kiyomi and Aiko, head of the children's ward, but are constantly tormented by the two artificial nurses. When Aiko stands up to them one day, the director brutally chokes her to death and decides to take the children for herself to use as experiments. With the help of Kiyomi, Kaori escapes to the surface with the children via a ventilation shaft, but not before Kiyomi sacrifices herself, leaving only her robotic head at the entrance. The head is later found by Professor Kajiwara, who restores an amnesiac Kiyomi into a new robotic body, naming her B-ko.
