Kotoko originally belonged to Yoshiyuki, but following Chi's kidnapping, Hideki and Shinbo forced Kojima to transfer ownership of Kotoko and her registration to Hideki so that her memories of Yoshiyuki kidnapping Chi cannot be erased.
Kotoko comes across as an emotionless character, but she can actually have a short temper and becomes very outspoken. She and Sumomo even each other out with Kotoko's calmness and Sumomo's craziness.
Kotoko is far more serious than Sumomo, and thinks that everyone in the Motosuwa household is crazy, with Sumomo in particular. Kotoko's specialty 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 often cynical, except when researching something, to the point of being tsundere or cold. Despite her personality she does eventually grow to care for her new owner and even Sumomo.
She is inquisitive due to her programing and her speciality is research, which twice drives the story forward.
Kotoko is 16 centimeters tall with long dark hair tied in two pony tails tied with two large-bells containing her pluggin ties. She has fair skin and deep-purple eyes. She also as a bob-like hair style with blunt-bangs. Kotoko wears a white kimono with a large red obi-bow in the front.
Role in the Series
Kotoko originally belonged to Yoshiyuki and her speciality is research.
After meeting Chii, Kotoko came to the conclusion that she was insane and clueless. She showed her inteligence by plugging herself into the computer and revealing her name, also revealing her master "kidnapped" Chii, much to Yoshiyuki's dismay because Kotoko cannot tell a lie because of her programming, even if it is unfavorable to her master. As a result, Kojima was forced to relinquish ownership of her to Hideki to avoid him erasing incriminating evidence in her.
Each time Chii came under the influence of Freya, Kotoko, like other persocoms, claim they can hear a "familiar voice" speaking to them. It was never clear who this was, but it is implied to be either Freya or Ichiro. These instances reveal her observations and fascination with Chii.
At the end of the series Kotoko remained in Hideki's ownership.
