Opinion & Informal

Art: 5/10
The art was about average. The fills and space use were average too. The extras and environments were also sort of basic. The anatomy and proportions checked out. There weren't too many impressive impact shots or art showcases; neither were there any environmental or panoramics. There were maybe one or two cases where the art looked pretty good; the first death is the first thing that comes to mind. However, many of the later deaths sort of had really bland and tame art. This manga is a forced killing game so one might expect some gruesome artwork, but I really felt that this manga was a bit underwhelming in that department. It felt like a PG-13 sort of thing.

Panel Progression: 5/10
This area too was average. The panel layout and progression were about average. Pacing overall felt a bit too fast. It would have been nice to go into more detail or character development. The quick pacing detracted a lot from the intricacies of the sleuthing, the atmosphere building, and character development. As a result, mysteries were boring, there was no sense of anxiety or dread in the air, and many of the characters never left any impact meaning it was hard to sympathize with any of their death throes. The use of panel cutting wasn't used too much but it was nice to even have it in. Overall, the panel progression was very average.

Characters: 6/10
Like I mentioned earlier, the fast pace of the development detracted a lot from the characters. Before I could even start to think about liking the characters they were already dead. There wasn't enough time spent developing the characters to a point where I could feel anything at all when they died. The character designs weren't anything special too. None of the characters had any design points that made them memorable; none of them felt like that had any flair or substance to their personalities. The characters were also plainly written. I saw it from a mile away (chapter 2) that the nice dude who was helping out the MC was one of the wolves. The two things that this manga did well though were how they ended up developing the MC at the very end as well as how it was able to show how isolated the yankee dude was the day before his death.

Plot: 5/10
An average forced killing game that didn't really add anything to keep it interesting. I don't know why the killers were labeled as "werewolves" when no mention or point was made supporting the name. Why not just have them as regular wolves? Why are the villagers being attacked specifically by werewolves and not just wolves when all of the imagery used in the manga clearly showed wolves and not werewovles. I'm assuming werewolves are the mythical beast of a person transforming into a wolf...so why not go further and support that plot point? All the illustrations referencing wolves and the way dialogue is worded honestly makes it feel like just the regular old wolf, not he mythical type. I don't know, I feel like the author was very mistaken on the differences between the two and the nature of how the folklore actually plays out and decided to use the word werewolf because it sounded cool.

Development: 6/10
Again, pacing was too fast to develop anything meaningful in terms of plot complexity, atmosphere, and character development. Things sort of just happened and the dread and horror were kind of just happening to the cast; this manga didn't really immerse me into the how the characters may have been feeling. I wasn't "a part" of the story, it was more just me as an observer which is a minus to me. The one good part about the development in this manga that I liked was the twist at the very end. I actually did not foresee that possibly happening so I thought it was a nice touch. I'm just waiting for the sequel to get finished before I pick it up.

Conclusion: 7/10
The twist conclusion was good. If anything, that's the only "good" part about this manga. Everything else about it is really underwhelming. The conclusion was good enough to get me interested in reading the sequel.

Overall: 6/10
An average killing game where there were only two highlights in my opinion. The one impact shot showing how isolated and desperate the yankee was towards the end was very well done in my opinion. I felt it really captured a glimpse of what he was feeling; a thing that this manga should have been doing for every character. The other highlight is the twist conclusion. I could see myself recommending this because of how short it is and how interesting the conclusion was to be able to setup momentum for the sequel.
