Started off good but went downhill

I remember reading this and liking the beginning, so I came back to finish up the series but god did it go downhill.

Spoiler (mouse over to view)
Natsume truly attempts to move on from being nearly raped, but Kou does not. At first we are led to believe that Kou left Natsume for "her own good." He was unable to protect her from the rapist, so he willingly gets out of the picture. He leaves Natsume so Natsume can find happiness with Otomo, who is the “nice guy.”

Ok, he gets into fights, he’s rude, he’s selfish, he’s turning into the stereotypical “bad boy.” But I still think he’s a good guy, trying to do what he thinks is right in a frustrating way. And the author was clearly letting us know that Natsume and Kou would get back together. When it happened, I thought I would be ecstatic. I shipped them. There was no way anything could go wrong. But yes, yes it did.

After the rape incident, Kou had no redeeming qualities about him whatsoever. And believe me, I LOOKED. I WANTED to find a redeeming quality about him. But all I found was reasons for Natsume to avoid him with a 10 foot pole. Just a few: he baited his brother into being beat up in his place, he pimped out a girl that liked him, forcefully kissed his brother’s girlfriend in front of Natsume to get back at her (and afterwards the brother slapped the girlfriend?????), and we haven’t gotten to the worst one yet folks. I still kept reading, hoping for a redeeming change before they inevitably got back together.

But here we go folks, the way they get back together. Kou basically blackmails, hits, and rapes Natsume. Repeating the first traumatic incident a second time. The author literally draws a superimposition of the old rapist on Kou since Natsume sees him as the old rapist. But then she opens her eyes and goes “Oh, it’s Kou.” She accepts it, because “he, too, was unable to move on” or something. Basically, she can't help but go back to “save" her violent, abusive, first love who showed no redeeming qualities whatsoever after they split. This all happens while she’s with still with Otomo, so she goes to break it off with him out of guilt.

I truly had high hopes for this manga when I started reading so long ago. But I can’t bring myself to read past this second rape. Apparently Kou turns sweet later on, and him and Natsume end up happily ever after. But does that negate what he did?

Just a couple of chapters make clear that this manga is going to give us a positively thrilling picture of how sexual desire feels to a girl who's never really felt it before. This is going to be a winner!

But I want to address some things here
Spoiler (mouse over to view)
I feel like Kou's character overshadowed Natsume's. As a character he is more intense, layered, and fascinating. Natsume is a strong female lead, she also has her own share of traumas and burdens, but I guess she's just a more realistic character than Kou.

There's something unsettling about Asakura's style here that is both lewd and elegant. Those eyes! Art style itself gave me guilty pleasure as I read this series in one sitting. There's so much more to this story than the usual web of tumultuous love between utterly flawed personalities. There are bigger topics that are tackled here that you wouldn't find in a mainstream shoujo. Children in a crumbled society with failed adults, a premature death of innocence, rampant with corruption and absent of love-- All dark and gripping. At times I thought "No! It's too much." Yet, it knew I needed more.
I thought I had issues with the character's ages at first, but the world they're wrapped up in is so believable that the way they behave makes so much sense, I'm vicariously nodding at ever dramatic turning point. Not to mention that world! Interweaving folklore, old money, and adolescent angst in a small country town governed by the sea and it's superstitions. Sound like a mishmash of genres? Maybe as I have described it, yes, but it's all there and all complementary to one another in order to deliver the unique tone of this well crafted story.

Gave it a 9 until the 50s where it ended up turning into the cliche type of shoujo where
Spoiler (mouse over to view)
The girl is finally properly dating the nice guy, tries to confront the bad boy, gets threatened into hanging out with him, gets abused, breaks up with the nice guy out of guilt, and finally gets together with the abusive guy. Who of course suddenly turns sweet a few chapters later.

So much wasted potential

I've only read up to Chapter 32, but this manga is amazing. The drawings and story were kind of lagging at the beginning, but as the story progressed, I really began to appreciate the art style. It's not lacking in skill - it is just a little grotesque, sort of. It shows expressions so well even though Natsume and Kou and Ootomo can be such indifferent characters. It's dark, brutal, yet charming and endearing. I love Kou the way Natsume does - I almost feel sucked in by his presence. There is just something about him that you can't put your hand on - "a blazing fire."

The story is also set around pulling at your heartstrings and writing things that normally you wouldn't want to see. In times where we hate the cliche happy endings, this manga really pushes the limits of that desire to see something "different." So many times, we are faced with disappointed in a bittersweet way.

Spoiler (mouse over to view)
You'd want to see Natsume saved. You'd want to see Kou show a flaw, but not in that way. I loved the idea of Kou being invincible, that it was "his land," that he had a god-like power that could sway and move anybody. This story started out as a typical model-girl story, but with her being thrown into a hickish town, everything changed. Kou is practically the embodiment of nature and life itself, and she is drawn to that. Risk-taking, fearlessness, and most of all - a purposeless passion. Kou moves her for no good reason, he brings about feelings she has never experienced - and she calls it "love."

As another person commented, I love how the story progresses through the character's life from since they were little. It's almost like Oyasumi Punpun in that respect as basically a coming of age story. I love their childish responses to their feelings and even danger. They are impulsive, they hate easily, they are violent...I feel like the mangaka captures the feeling of uncertainty and fleetingness so well, and the idea of centering the story around that is just profound. Even down to the jagged and faded lines of the drawings, this manga embodies and speaks a great deal of sense on the matters of passion and the inevitable.

Spoiler (mouse over to view)
Kou is transient, mysterious - one moment he is there, he is interested; the other he is gone and practically dead to you. It's a strange yet endearing character flaw/trait.

I'm so hyped about this manga that I may start to read chapter summaries...

Quite profound

I picked this manga up, expecting to drop it after 10 or so chapters when I got bored of some crybaby heroine chasing after her prince. Superficially, that's what the manga seemed like in the beginning. But as you read on, things start weaving together bit by bit like a tapestry. At first, the story is told through Natsume, but then you begin to see other perspectives like Hana, Ootomo, and it really adds to the overall understanding of the plot and the attachment you feel towards the various characters.

Throughout the story, the characters change both physically and mentally. Most shoujo mangas people only 'grow' in terms of their relationships to one another, and rarely do they portray characters evolving and being changed by their experiences. With this, I felt like I was watching the characters evolve from kids to adults. Despite being shoujo, the topics are quite dark and profound.

The art is pretty good in general, but I'm not a fan of characters blushing on every panel. The story is really what convinces me to continue reading.

Comments that may contain spoilers up to Volume 14 below:

I hated Kyou as a character for the longest time. I generally dislike characters that fight for the sake of fighting, and was never able to empathize with him after the incident. His character deteriorated from being the center of Natsume's life, to this annoying pest that would show up once in awhile and bother her. I cheered for Ootomo all the way, hoping that she would stay as far away from Kyou as possible. When Ootomo and Kyou were together, I just kept wishing that Kyou wouldn't come and destroy it. But... later on, Kyou is gradually redeeming himself. As more of his backstory comes to light, his character is growing on me. Not quite a Natsume Kyou shipper yet... but we'll see how things progress.

// Update after Volume 14:
After Kyou practically rapes Natsume... I hate his guts.

This is the kind of story that simply captivates you. It's rich in emotional and situational tension and shines brilliantly in story telling and character portrayal. But what this story does that is so unlike most stories - is that it has this unusual power to overwhelm you. To give you this deep, but modest understanding of youth in all it's shameless glory.

What do I mean by that? It's all those powerful feelings - the elation, the disappointment, the anticipation, and that familiar dreamy longing for time to stand still, to live in seemingly perfect moments. If you've ever been an over-idealistic dreamer in your youth you'll be easily wowed by this as I am.

But apart from my abstract/personal thoughts: It's a great dramatic romancey slice-of-life sort of manga. Natsume is a strong character, but understandably weak too. We hear all her thoughts and watch as time and situations change her perspective of things. And I love the romance. I like that her relationship isn't smooth, but rather unstable and realistic. Her relationships between the main characters are a bit unpredictable (boys and girls alike).

Read it and be taken by it.

Hmm, I've been meaning to read this for a while now... I was a bit hesitant because the plot's not what I usually go for. I thought it would be melodramatic and cliched, but the story really draws you in. Despite Kyou being the "bad boy" type that I detest, there's just something... magnetic about him. He and Natsume are just strangely interesting... I can't help but want to know more.

Compelling characters, masterful storytelling, layers and layers of complexity not to mention the gorgeous art--This one's a keeper.

First of all, I LOVE this series. Natsume has won my loyalty, and I just want her to succeed in everything. She is not only a strong character with a mind of her own, but she deals with problems in a very realistic way. It is also clear that her ridiculous beauty is a curse rather than a gift. Seriously, her life sucks.

Kou is also one of the most interesting male leads I've encountered in shoujo. He's pretty crazy, but it makes sense in context. And make no mistake, this may fall under the category of shoujo but is no light-hearted romance.

I highly recommend this series for anyone who likes character development, slice of life, coming-of-age, or romance stories. Oboreru Knife is one of my favorites!
