Well.. I give it a 10 without thinking twice!
I've read the manga and watched the anime, both good, but nothing compares to the original (manga).
Each character's showing a different moral aspect of the story.
I especially like Chidori-san, coz she plays well the role of "reality-check". She represents what most people in society think and say out loud about incest.
I find Nanoka a bit stupid at times. Don't confuse that with her innocence, being innocent is okay with me. I'm talking about stupidity. I think that there's a small contradiction in her character: she apparently has less shameful feelings than her brother about their relationship and she even says to Chidori "why can't siblings get married!?" and on the other hand she is keeping their relationship a secret from their parents and even from her best friend, Futaba. In my opinion the mangaka could have put some more effort into Nanoka's character's behavior. Besides that, the manga is so heart-wrenching and is delivered very well, emotionally. Not too fast nor too slow, and I like that.
I've read it for about 8 times I think in the last 6 years, since I've first read it and watched the anime version of it for like gazillion times.
I believe that a story is considered good only if you know that you'll never be able to get it out of your head.
I totally recommend it to anyone who hasn't read it yet.

I really liked this one overall. The story itself, despite being a little drawn out, was done really well. It was so romantic and yet so sad on a few occasions I was almost moved to tears. The only gripe I had regarding the story was that it was a little confusing at times, perhaps because of the translations. This could have easily been a 10 in my book but because of the mediocre art and poor plot/translations I will have to settle in at an 8. Still though, this was a really good incest manga and well worth the read.

This may be a fault of the translation but there were a few chapters in the end where I had no idea what decision the main character had made. (around the cafe part and onwards for a few chapters)
The first few chapters seemed like it was jumping between plot points rather than showing them developing. It's not made clear enough that their original encounter had such a large impact on the male main character. His and his sister's feelings are conveyed but the development isn't.
This improves during the series, but not by much. Again, some of this may be a fault of translation, but some of it clearly is purely on the mangaka.
The female main character's best friend is also poorly written, having no character. I also wish those thoughts of her's that we read last were clearer. What precisely was she talking about? How much did that planner reveal?

I'll still give this a good rating because it did evoke some melancholy and such in me and because it's a romance. And the romance genre has very VERY few manga that don't suck.

But there are other romances I would recommend more. ("Tokyo's Casanova", "Girl Friends", "Sasameki Koto", "Kimi ni Todoke", "Haru,yo Koi!" and so on..)

Of course, there also the possibility that my opinion will drastically change over time, having just come out of reading it a few minutes ago
Oh, and perhaps I should mention that I was kinda sleep-deprived while reading this. But, anyways, from what I've read (EDIT: as in, on wikipedia. I was trying to find out what I had just read, due to the lack of clarity), it seems the anime has a lot more clarity. Though it changes things, they seem to be good condensations.

Surprisingly moving and sad. I imagine this is what it was like for some homophobic readers coming across "taboo" material back then and even perhaps now. And in spite of my own )confused_ feelings/views, I found this to be touching. So... I've concluded that consensual incest is none of my business.

As an avid shoujo reader that has yet to grown out of silly shoujo mangas, this manga is totally the type I would never read. Because of my love for incest (Flowers of Evil started this), well, I gave it a try. I must say so myself, this is the best incest manga, honestly, it's so touching and it made me cry (I never cry for mangas). At first I was iffy about the art and the age gap, but, the emotions, etc, etc must made me want to read more. This is not just incest, this is romance, an awesome one at that. Like some people say, the ending felt, I dunno... I think it needs more closure, but nevertheless, it's okay I guess that it was left the way it was and sad at the same time (this should have an ending like in this other incest manga I read). Please read if you like bittersweet romance and that you can tolerate non-shoujo art and the age gap.

This is one great manga. The only thing is the difference in size. It kinda get to me during the first few chapters but catches up later. The ending is a bit disappointing because I wanted to know more. The story is interesting. The character are great and character development is good. Yeah, this is definitely incest. Give it a try. Don't just judge it by the incest but by the story......... the feelings that you'll come across. Read it with an open mind.

I like it when Koshiro is not a good looking "prince" and that Nanoka is not as bratty as I thought she would be. One thing that bugs me is Koshiro's size... I know he's big sized but why did the author make him "that" big... and the other thing that bugs me is that they're blood related. Well anyways, I liked the story, I usually hate incest but this was good - I liked this as much as usagi drop!

I'm not going to sit here and pretend that I hated it or that I absolutely adored it, because neither was the case. It was just one of those 'eh' mangas that left you with a mediocre ending and characters who didn't seem as compatible with each other as they themselves would have liked to believe.

What frustrated me the most were the inconsistencies with the characters---especially the 'brother' (I can't even remember his name). It's like he was trying to convince himself he liked her one minute but then the next, he's back to being a lonely old man---make up your mind already!

I've read some of the comments on here, and while this is just my personal opinion, I think this story goes beyond "looks". Yes, the older brother was a bit too old and unattractive. The sister says so several times, but that wasn't what she saw in him. She saw past the physical to the person he was inside and that's what she fell in love with. The world is far too hung up on looks, to be honest. Many "beautiful people" are downright UGLY inside, and some who are deemed unattractive have the purest hearts.

But back to the manga, yes?

I'm a fan of incest manga. I find it entertaining when it's not real. I don't get grossed out easily, particularly when something is fake. It's a story and it's only as "nasty" as the reader makes it. My issue is that it was fairly boring. But I'll give points where they are due:

1) The mangaka did her job as far as character development and showing how this introverted, somewhat selfish, emotionally bankrupt person was able to change into the very opposite with love and patience.

2) She showed how a somewhat spoiled high schooler matured and learned to stop being two different people in front of each parent as well as come into her own as a young adult. (My gripe is that she looks 10 years old throughout the entire series, which doesn't help people get over feeling like they're reading ped/loli).

3) This story played out like a bit of a film -a long drawn out film, but cinema, nonetheless.

*MILD SPOILER ALERT*

Koi Kaze isn't a necessarily bad story. Several times it made my eyes tear because it was somewhat touching, particularly when he nearly gives up on wanting his sister's love, or another part when they are in two different places and both reach out to touch the falling snow. There's a gentle sweetness there that can't be denied.

However, it shouldn't be rated 'mature' by any means. The physical intimacy, if one is looking for that, is non-existent, and the artwork is awful. The story, for me, drags unnecessarily and the ending, well, what ending?

IMO, Koi Kaze had the potential to be more than what it was. The development and pace was too slow and unexciting when it could have held my attention a bit more.

Terrible? No.

Great? No.

But it's a decent read if you're not doing anything else at the moment.

as others have said before me, this is a fantastic series. with the way that the characters and story develop, you feel like you are watching the story unfold instead of just reading another manga. when i first started reading this manga i thought the incest would bug me a lot. i found myself, however, not being bothered by it and actually rooting for them (im not going to lie, that kinda creeps me out in retrospect.) my only complaint about this series, is that it didn't show you everything that was happening like (SPOILER ALERT!!!) in the last chapter when nanoka tells her brother to stop deciding on his own and uses him talking about proposing with his mother. it was hard to tell if they didn't show you something and nanoka was getting married to him, or if she was just talking about him saying he wasn't ever getting married. over all this was a great series though, and i recommend it.
