I added a translation for the D.Gray-man Fanbook Chara Gray. It’s an interview with Hoshino Katsura. She talks about the results of the Character General Election (results were published in the fanbook), the Alma arc, her research trip to New York, the fan signing event she held in Germany and Japan and other things. It’s from 2011, but it’s still a good read.
You can find the translations under the D.Gray-man page.
