If you can't see a manga in Manga Rock, it is mostly because of licensing issue. Local publishers contact us to remove their copyrighted content.
If you can't see a manga in other languages beside English, please note that the Play Store version of Manga Rock now only contains one English source. This is because we were previously removed from the Play Store due to objectionable content appearing in our app coming from other sources in other languages. After a long time appealing with the Play Store review board, we were able to get the app back on store, but we are forced to only use one source so we can reduce the risk of the app being removed from the store.
However, we have the official Definitive version hosted on our website, which will give you access to all these manga, in multiple languages.
