Ok WTF these new characters. Ok the TL notes of these new character sums up my feelings as well. I actually DID read that other manga and I didn't bother trying to unravel that clusterfuck.
@ieatass69 It technically is, in that by the end of Mahou Shoujo Site's 15th Volume it introduced characters from Mahou Shoujo of the End, who will presumably have a role in the story in the future. It also seems that the final antagonists of both stories are the same character.
The Japanese version of Chapter 133 in digital is taking longer to come out than expected. Even though I'm not associated with Kanami-chan/Kanami-chan's group, I'm pretty sure this means the translation of that chapter will take longer than expected.
