I don't know if it's because I've seen the anime so many times, and this volume covers so many of those storylines, but I found this volume hard to keep my interest .
The art is a big problem for me. It's very busy and cluttered, where I prefer cleaner, sparer compositions. Ginji looks like a butch girl. Hevn's breasts are even bigger here than they are in the anime and they practically have their own subplots. Which leads to the next problem. Her huge breasts are constantly being heaved into the readers' faces and everybody plays with them. I'm not fond of the gratuitous female near-nudity and panty shots. I know that this is a convention in much manga, but I really don't like it.
Then there's the brief appearance of Kazuki the Seamstress. I've heard that the last bit might be fixed for the next volume, but on top of everything else it really killed me.
More improbable super-powered hitmen. Less fan service, which is either an improvement or not depending on one's point of view. Decent diversion, but probably not anything I'll reread.
