So, my biggest complaint with the last volume was the lack of Gen. He is definitely one of my favorite characters. And wouldn't you know it, this volume didn't feature him either! Well... it did, but only barely and it wasn't anything new.
With that being said, this was actually a very awesome volume. For the first time in the entire series, Usagi is in one place from start to end (minus some additional content at the end). The entire volume is about Usagi helping Inspector Ishida solve a series of crimes in his city. There are some other recurring characters like Kitsune, Nezumi (who is kinda new), and Inspector Nii. But no Gen :(
It really was good though. It read more like a mystery novel and the intrigue and drama were quite compelling. Lots of really great stories and really different than anything seen thus far in the series.
So, Gen did have a brief appearance. The end of this volume is made up of all of the Usagi/TMNT crossovers. It was really cool, but the problem was, that most of it was stuff already featured in other volumes. It was just gathered together here. Good stuff, like Usagi, Gen, and the turtles taking on the Neko ninja, just very little new material.
