Did the author provide a reason why he doesn't want it to be translated? This manga is available to read for free online. I don't see how translating it could be considered a gray area even for the guy who was taking money for it.
Hopefully this'll be an "exists to push along the plot and disappears after 5 chapters" character and not a "causes drama for 5 volumes and completely halts any progression" character.
Looked at the author's tweets, and all I can say is yikes... He really just told people to learn a whole language if they wanna read manga, huh? And people wonder why scanlation is so prevalent.
@baconcat Yeah, it's easy to guess what the names might be. The problem is that we almost never know for sure, unless there's an official english release or something. Even then, a lot of the times they completely change the names for localizations.
