Synopsis
Miki Shiba owns the Villa Rosa Sasazuka apartment building where Sadao Maou and Suzuno Kamazuki live. Despite her ordinary appearance as a Japanese landlady, she seems to know far more about Ente Isla than any typical Tokyo resident reasonably should.
Staying largely in the background, Miki quietly acts as a kind of guardian of Earth, keeping a watchful eye on her unusual tenants without giving away her own secrets too soon. Her family ties — to a niece, Amane Ooguro, and a distant relative of Satan himself — hint at a far deeper history than her low profile suggests.
