A shadowy but powerful figure in Japanese industry and politics, he built his fortune and influence through control of Sakuradite mining—the resource that would eventually make Japan strategically invaluable. During the Kururugi Administration, he was one of the regime's most important behind-the-scenes operators.
When Britannia invaded and occupied the islands, he made a calculated and very public show of support for the new order, earning him a reputation as a collaborator and traitor in the eyes of most Japanese.
