Due to the fact that Manga Rock was previously removed from the Play Store because of objectionable content. In order to reduce the risk of the app being removed again, we have to take down these following genres: Adult, Mature, Yaoi and Yuri.
You may also not able to read some manga because they are "not available in your region". This is because they have been licensed and taken down as requested by the original publishers.
However, we have the official Definitive version hosted on our website, which will give you access to all these manga, in multiple languages.
Step 1: Go to your device settings > Security > Turn ON "Install from unknown source"

Step 3: Install the app
Step 4: Restore your data from backup on Manga Rock Cloud
