During Yakuza 4, Daigo holds an emergency meeting with the Ueno Seiwa Clan following Ihara's death. Isao Katsuragi, the head of the Ueno Seiwa, demanded from Daigo that, to make up for Ihara's murder, the life of Arai or control of the business Majima runs, but Daigo refused. He was then asked by Katsuragi to use Majima instead since he is the "only one to measure up Ihara's murder."
