The landlady, voiced by Yukina Fujimori in the online versions and Akane Sanada (using the alias Ruka Momochi) in the DVD releases.

The title "Dokidoki Little Ooyasan" translates roughly to "Heart-pounding Little Landlady," hinting at the central dynamic of the story.

The titular "Little Ooyasan" is Miyuri Asou . Despite her youthful, petite appearance, she is canonically older than Tanaka.

The core hook of the series is Miyuri's unique approach to property management. As a "reward" for tenants who pay their rent on time and in full, she provides intimate, personal services.
