So... what happened to the links for the manga scans?
- Nothing in the past 15 chapters i.e 15 months has borne any fruit on God Eater 2 material that we don't know about, making it unworthy to mention.
- The sites that host the Chinese scanlations contain ads that are generally perverted and not safe for work.
Due to both reasons 1 and 2, the links were removed.
If it still holds any interest to you, one of the aforementioned host sites is here.
If there is cause against reasons 1 and 2, the links will be restored, but I doubt that will happen as the manga is filler material and is generally made for the purpose of attracting newcomers to the series. People who have played the series will seriously not find anything ground breaking in the manga.
