Known in online circles as "Dragonfly", Yoshiyuki Kojima (小島 良由起 Kojima Yoshiyuki?) is an ego-driven custom persocom-builder and a man willing to overlook scruples to learn more about building better persocoms. Unlike Minoru Kokubunji, he is more obsessed with persocoms and even kidnaps Chi during the course of the story. He attempts 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, he is seen assisting Minoru to help solve the mystery of Chi and the Chobits. He mentions that Chi "is too interesting a safe not to try and crack!"
