Of course they had to show up. The chapter had such a nice atmosphere going--thought a good chapter or two without psychopathic mob presence was coming, like the end of the school festival or the time Mone went to visit Nobuyasu at his house.
Can't have that too easily with a beauty like Mone though, right? Not when there are fetishes to satisfy.
Would be nice. There aren't too many chapters left, so it's got to come sometime soon, right?
