I grabbed this manga because the summary attracted me and it sounded like a good psychological manga, well it sort of is and not. To be clearer I really enjoyed the first two chapters, because they built up to great suspense. But that was it, for me those chapters were the best and made me expect even more or at least the same level of suspense further. It didn't happen, the manga levelled off from there on. There really isn't one main character, but most of the manga revolves around the two hitmen. The events in the manga happened too fast without much insight into the characters' psyche. The manga would've been better if it focused on the feelings of the hitmen, especially Shiki, how he felt after each job or Kuzumi's past. A psychological element, instead of a supernatural one (yes there is one, it really did shock me) would improve this manga. I guess because of the inclusion of 'murder', this manga is designated seinen, but it hardly even passes for shounen.
Story 6- it is interesting, but could've been made more suspenseful. More mysteries are introduced but hardly addressed again, like the 'corrdinator' or the organisation that hires the hitmen. The targets (for the hitmen) r supposed to be evil, so that they won't stain on their consicous after killing them. But hardly two or three lines r said about targets' evilness, I wished more focus should've been shown on their crimes/activities. Some gore should've been added, so at least the 'evil doers' would've seemed evil.
Art 9- I rated it high because it's almost bishoujo, really pretty characters. But there are not enough details in the background.
Characters 6-As a reader I would like to feel somewhat empathetic to the characters. Since there wasn't much focus on their background, except for Shiki's and his reason to kill (very unoriginal btw- sister in hosipital with cancer). I felt there wasn't any depth to the character, the manga barely scraps their surface. There were also too many characters interoduced too fast, that they were hard to remember .
Enjoyment 6- I did enjoy reading it, but it didn't really make me think while reading it. I didn't really need to use my brain much (like a shoujo manga). I'd probably keep reading it to see how it ends or gets any better, but I definitly won't be re reading it.
Overall 6- The premise is promising, but the manga doesn't build on it enough. If it were to become more gory or darker I'd raise its rating.
Well that's all I can say about it, it's my first review and I tried to follow others' review template, so I hope it's helpful to future readers.
