This is still an enjoyable book, but as a whole, Kemono Jihen is starting to suffer a little from not having a central villain. You could argue that Inari fills that role, but she's usually just off in the background, doing her own thing. Lacking a core antagonist isn't immediately a bad thing, as it can be done well, even in a shonen/seinen series--just look at Dorohedoro. For a sizable chunk of that story, there really is no one you could point to and say with authority, "that person is the villain." The difference between that series and this one, however, is that even when the story took a detour here and there, there was were strong main goals driving not only the heroes, but a lot of secondary characters as well. Kemono Jihen sort of has that. But...
The thing is, we're quickly burning through those character motivations. In general, our heroes all want to reconnect with, or learn more about family members they've lost...and in the span of a few volumes, we've more or less met those goals for Shiki, and now Akira. Kabane still hasn't reconciled things with his parents yet, but his is really the last remaining goal of the group. That leaves the rest of the story feeling a bit directionless--not quite "enemy of the week" or anything, but it does feel like the characters just kind of coast along until a case or coincidence happens to bring them to their goals. With the (rather disturbing) way this volume ends, maybe Akira's extended family/clan is going to become a major threat, but we'll have to wait and see.
On the upside, the art is still great, the characters are still likable and genuine, the action's solid, and the world Aimoto is building is an interesting one. But the directionless nature of the overall story could really benefit from something to give it a better sense of focus sooner, rather than later.
