I felt like this volume highlighted problems this genre inherently have. Too many girls and the MC need to somehow be nice to them all to get them to fall for him, but by doing that, it make the characters felt more 2 dimensional. The drama also felt unnecessary at times.
Invaders Of The Rokujouma vol 12: staring from this volume the structure of the story is changing, and that's a good thing. This volume was longer than others and it contained a lot of action scenes and a lot of progress between characters relationships it was very good 9/10
