D-room Books is a free eBook service exclusively for residents of D-room rental properties who are members of the "my D-room" tenant-only website. This service allows users to choose from a wide range of genres, including manga, magazines, and picture books, and read eBooks for up to 120 minutes per day at no cost. Please note that the daily reading time is limited to 120 minutes for health reasons.

The viewer's features include the ability to read both horizontally and vertically, making it easy to navigate through the pages. When reading comics in vertical mode, the text can be enlarged by rotating the screen horizontally. Additionally, users can slide vertically while in horizontal mode, allowing for a smooth and comfortable reading experience. The page navigation is also seamless, allowing users to quickly search for specific scenes, similar to flipping through the pages of a physical manga.

D-room Books is a convenient and user-friendly eBook service that provides D-room residents with access to a wide variety of digital reading materials.
