Patriarch of the Minamoto Clan, a Rokujou Group subsidiary.

Hikaru is a gruff and taciturn man of considerable height who leads one of the many clans that make up the Corporate Risk Management Sector of the Rokujou Group. Tasked with eliminating threats to the security of both physical and financial properties owned by the Group, Hikaru takes his job very seriously, carrying out assignments with complete loyalty. As the sukeban have become more organized, he and the biosoldiers under his command have been tasked with cleaning up.

Hikaru speaks calmly and slowly with careful enunciation and formal diction. He should have a deep voice that carries with it the weight of authority and perhaps a bit of resignation. Sometimes he comes across like a strict instructor.
