Seeing the groups that both released chapter 1 working together to put out a joint release is definetely one of the most wholesome things I've seen lately.
@Dragons33 The "official" translation to "灰かぶりの魔女" is "Cindery Witch" (see cover as well), so despite the great resemblance, it doesn't seem to have any connection. "Ashen Witch" is also correct as a translation, nonetheless.
@YuuyaYTB This isn't because of the numbering. It is because the other group didn't add the volume number when they uploaded the chapters. Still, that is a Mangadex issue, anyway.
