Івакура Ясуо

Passionate about computers and electronic communication, he is shown as working with Eiri Masami at Tachibana Labs. He subtly pushes Lain, his daughter, toward the Wired and monitors her development until she becomes aware of her condition.

He leaves her telling her that he did not enjoy playing a family, but did love her. He seems eager to lure her into the Wired, but warns her not to get overly involved in it.
