It's not a Shiga Hime chapter without titties. Guess it's back to the same plot since chapter 1. I know Japan likes to recycle but damn Author you're doing it too fast.
@dovahcrap is mistaken, chapter 31 is the last chapter, Volume 5 indeed is the final one @lastKANAshimi
Also quite frankly it looks like a better package this way, if this went any further it would make it seem the author only wanted to satisfy his need for guro instead of trying to tell a story.
