He is the director/head/whatever of Easter Company. He is the stepfather of Ikuto and Utau. Well, a pretty evil one at that. He can also be described as out-of-shape old pipsqueak.
Who is Gozen?
He is the president of Easter. At first he is a mysterious person, but prepare for a great surprise when you read Chapter 40.
