Lucky★Star, Vol. 7

I've been following the Lucky Star series from volume 1. After reading volume 7 it felt like the jokes were either not there or too obscure to understand or notice. I probably won't be buying volume 8.For anyone paying attention to the story the original characters have now graduated. So a fair amount of the panels use a lot of the now large (and still growing) cast of supporting characters.I also want to moan about the number of adverts in the back has increased to 10 pages (compared to 0 in volume 1)! Several times I seriously considered putting a bookmark on the translation notes page to make it easier to find.
