- One day Heita Fukai (Sato Takeru) finds a girl sleeping in the science lab. When Heita touches the girl, she suddenly wakes up and opens her eyes. The girl (Maeda Atsuko) was actually brought to the lab by school principal Jiro Kishimoto (Ono Takeshiko).
The next morning the principal notices that the girl doesn't breath at all and he asks for help from teacher Tatsune Ogawa (Yuji Tanaka). Tatsune Ogawa recommends that they should remove her from science lab. When they get there, they find Doctor of Engineering Kuriko Yanagi (Hiroko Yakushimaru) is in the lab. Kuriko notices that the girl is actually a robot with human looks.
A secret does exist within her....
