Manga 3415 Kure-nai

Although I was quite hesitant to start it, But I'm really glad I did as the story is pretty decent, also liked the whole Murakami arc (which is also animated in Anime). As it is an Action manga, so u may find the ML to be edgy somewhere (found it it only once)

~Minor Spoiler warning:
The backstory of the ML is same as of classic shounen manga, Like the trauma of losing his parents in early age, and he get supported by a outside family which adopted him and also by his childhood friend (Ginko) which acts as a informer for him for various disputes he ... takes. The other characters includes Tamaki (A playful senior which teases the MC often and is ridiculously strong), Yamie (a laidback women who likes to rest), Kirihiko (A blonde, belongs to a assassin family) who just want to make friends.
The manga is about how the MC helps all these characters and also how grows with them

Overall, I like the story and the 2 ova's are adapted is same art style as of manga so it's a must watch for the peeps who enjoyed the manga.
Recommended: 7/10

tl;dr: A manga that gives strong arcs to a lot of characters, though is very lacking in relationship development beyond the setups. 

This is a manga that’s an adaptation of a light novel, and though I haven’t read the manga, I think the manga stands up pretty well in and of itself. It's a very character focused manga, but at the same time it’s kind of strange in that almost all the major relationships are established before chapter 1 even begins. There are flashbacks that help provide background, and most characters have arcs that help flesh them and that relationship out some more. However, with the ... exception of Kirihiko who is introduced during the course of the plot, the state of essentially every relationship is the exact same during the final chapter as it was in chapter one. The ending seems to try to do a finale that focuses around this, but the ending isn’t very final, nor does it have much impact, but I suppose it is a nice and happy enough note to end on. Still, even with this issue, the majority of the manga is quite interesting. Strangely enough, while relationships don’t develop, most every main character has a pretty strong arc. Murasaki, Shinkurou, and Kirihiko have the most time spent on them and definitely come out with the strongest development. The other major characters, Ginko and Yuuka had character arcs, though they weren’t as strong, though they both still remain quite likable. There are various other side characters as well as villains that all manage to get some development, though not much, and many that felt that they should have gotten more. This is where it most feels like the manga doesn’t adapt everything, and that plot threads and conflicts remain that need to be resolved. Still, it does feel like the manga manages to get through a substantial amount of story and do at least somewhat well by a large number of the cast, which was somewhat surprising to me as the anime essentially only focused on Murasaki. The art style was pretty good, though quality was only decent. I definitely like the tone, atmosphere, and style quite a bit more so than the anime though. 

It started with "What the hell is going on?!", in the midst will make you shout "What will happen next?!", and at the end will make you shout and cry "I WANT MORE!"

Note: This is not a manga aimed for lolicons ^^

Kure-nai started wobbly. If that's how the author intends it to be is something I wouldn't be able to figure out completely. Characters and terminologies pops out one by one without warning until it makes you say "No more, I want to drop this." But hey, hold your horses, because after a few chapters, a long flashback shall be introduced.

Kurenai Shinkurou is a dispute ... mediator. At the beginning, the series will throw you various random missions for Shinkurou that has nothing to do with the overall plot. Then a magical flashback will commence explaining things to you what the heck was going on. After those flashbacks, I tell you, you'll want more of what's to come.

The story is not that violent. Kidnappings, mass murders, suicides - they are at least mentioned in some small corners of the series, but it is not that dark as oppose to other "secret-agent" feel some series have. In fact, this series is funny at times. And when the harem time comes, it feels like your typical rom-com-harem moments.

Character-wise, Kure-nai introduces a lot of interesting casts. While the main cast overshadows the minor cast tremendously, the harem members of Shinkurou are lovable to the extent you wouldn't mind that it is a harem. If you are not fan of the cliche harem scenarios, treat this thing differently. It doesn't force the romance vibe this series have down to your throat. Actually, I would love to see more of this harem moments if possible.

Most of the characters were fleshed out and extremely enticing. You'll get attached to them so fast. And if you are annoyed in seeing whinny and weak protagonists, good news for you, Shinkurou may not be the strongest guy out there, but he is certainly not the guy you want to punch because of his annoying complaints and misfortunes. And don't forget the other characters too, not all of them are combatants, but everyone has their fair share of showcasing their strengths throughout the series.

The art style was pleasing to they eyes; it wouldn't strain you. Some manga has so much clutter especially on these type of stories, but this one diverts from the norm. It may not be worth praising, but it is definitely something you'll love for a while.

The story arcs were all interesting and gives more value not just to Shinkurou, but also to the rest of the cast. Unlike some series wherein they just add story arcs to prolong the story, each story arc here has its own value and may change the whole outcome of the story if not included. There were also some mini filler arcs, but you wouldn't even notice them as something unimportant.

Overall, Kure-nai was an enjoyable ride. It may not be a page-turner, but it is still worth your while during your vacant times.
