Yoshiyuki Kojima (Dragonfly)
Known in online circles as "Dragonfly", Yoshiyuki Kojima (小島 良由起, Kojima Yoshiyuki?) is a man of few scruples and another custom persocom-builder. Unlike Minoru Kokubunji, he is more obsessed with persocoms and even kidnaps Chi at one point. He tries to hack into Chi, using all of his persocoms in a massive parallel processing network. During this time, he makes an ill-advised attempt to inappropriately touch Chi, and Freya takes over, restraining him with all of the cords attached to her. She then attacks him with a concussion blast, blowing out the windows in his house and knocking him unconscious. Afterwards, to make amends for his actions he lends his help to solving the mystery of Chi and the Chobits.
Yoshiyuki is the original owner of Kotoko.
