小山 鏡子

Arisa's widowed older sister. Her late husband had connections to the Yakuza, and left her with an enormous house. She is incredibly doting on Arisa, but their relationship is strained from her essentially having to raise her. She would give anything to her, and had married into money for her sake.
She is still on great terms with Kiriko.
