Gozo Aida (相田郷造) was an active industrial spy, but rode on the chance of the catastrophic earthquake and entered the salvager business, setting up K2 Corporation, a Salvaging operation. He is Rion's father. He prefers to hold onto the old ways (cheapest price for the best service) and principles of doing business, which does little good to the business. His past with Aika goes far back.
