Shiho, mother of Miho and Maho Nishizumi, is a cold but very talented senshado representative. Her high ranking position in the Japan Senshado foundation makes Shiho quite wealthy as well. Her main focus is victory and honour in senshado, even if it means disowning her own child. She is usually proud of Maho Nishizumi, but she disowned Miho Nishizumi. Miho Nishizumi is her youngest daughter, and Maho is the older daughter. She left her husband Tsuneo because he tried helping Miho.
