Kotoko
Kotoko (琴子?) is a laptop-sized persocom, like Sumomo, but, she told Chi, "I am desktop powerful." She was custom-built by Yoshiyuki and has much higher specifications than Sumomo. Kotoko originally belonged to Yoshiyuki, but following Chi's kidnapping, Hideki and Shinbo force Yoshiyuki to transfer ownership of Kotoko to Hideki so that her memories of Yoshiyuki kidnapping Chi cannot be erased. Kotoko is far more serious than Sumomo, and thinks that everyone in the Motosuwa household is crazy, Sumomo in particular. Kotoko's speciality is research, which twice drives the story forward. Kotoko is also programmed to always tell the truth, no matter what, even when it works to her owner's disadvantage. She is serious and cynical, except when researching something, to the point of being tsundere.Voiced by: Yukana Nogami (Japanese), Kari Wahlgren (English)
