Geez, so many of these chapters end with another girl coming in to save the day -- only to get immediately raped in the very next chapter before she even has the chance to do anything. I mean, couldn't the writer have them at least to put up SOMEWHAT of a fight beforehand? Because this is just making them look incompetent.

Also, who put the "original" tag? Because this isn't original, it's a cross-over of two other works.
