Kotoko

Height: 16 cm

Kotoko is another laptop persocom, like Sumomo, but she was custom-built by Yoshiyuki and has much higher specifications than Sumomo.

Kotoko is far more serious than Sumomo, and thinks that everyone in the Motosuwa household is crazy, especially Sumomo, although she herself occasionally exhibits a sarcastic wit. Kotoko is programmed to always tell the truth, no matter what, even when it works to Yoshiyuki's disadvantage.
