Very interesting statement from the official Princess Connect: ReDive twitter last night:

Why formalize the naming conventions in English, if there is no English translation planned? A couple weeks ago at Anime Expo, Kimura Yuito, producer of both Grandblue Fantasy and Princess Connect, was interviewed by several different folks, some of whom asked about an English translation for Princess Connect. The answer was always, “we’ll see, if there’s interest.” In one interview, he even said that any publishers or localizers that are interested should get in touch.

Maybe someone did?
