The phrase refers to the action of acquiring a specific application package file, optimized for the Android operating system, which provides access to digital comic books originating from Japan. This process typically involves obtaining the installation file from sources other than the official Google Play Store.
The significance of this action lies in the potential ability to access a wide range of Japanese comics, sometimes offering titles not readily available through conventional channels. Benefits can include offline reading capabilities and the potential for a user-friendly interface tailored for manga consumption. Historically, such acquisition methods have arisen from desires for expanded content access, region-specific content restrictions, or alternative distribution models.
