Takako  

Humanoid 2, 孝子

A gynoid named Taki was an artificial intelligence created by Dr. Ashino. When she got separated from him, she encountered Chihaya who helped her escape the guards sent by Dr. Ashino to bring her back to his lab. Although Taki is worried about Takis well-being since she doesn't know what happened after their escape, it seems that Chihaya knows where he is.
