The boyfriend:
Makes his girlfriend his "toy"
Acts like it's his right to punish her sexually when she's made him mad
Suspects everything with a dick of wanting to fuck his girlfriend
Doesn't listen to his girlfriend when she tells him he's hurting her

The girlfriend:
Acts like it's her boyfriend's right to sexually abuse her when she's made him mad
Acts like it's fine that he called her his "toy"
Considers herself a bad person when she "allows" anyone other than her boyfriend to rape her
Is raped practically every other chapter
Thinks that her boyfriend always knows best, so if he criticizes her, it's her fault for not living up to his standards
Thinks that when her boyfriend actually does listen to her when she tells him to stop (which is almost never), he's the kindest guy in the world
Apologizes for being so selfish when, (and this happens rarely), she's actually the one to ask him to give her a hand job, rather than him forcing himself on her

The plot:
Sex, rape, rape, rape, sex, rape, oral sex, rape rape, make up sex, rape
You get the idea. When the main character isn't being raped, the manga is made up of painfully obvious dialogue and plotlines. It's so bad, it makes me want to kill someone. namely, whatever pervert wrote this crap.

The main character is in a horrible situation; she's basically stuck between being raped by her boyfriend or being raped by strangers. And apparently if it's her boyfriend then that makes it okay or something. It's just so sick. I mean, the boyfriend is treated as some sort of hero or something, when in reality he's just a controlling rapist.

This is just a sick sick manga that mocks these types of situations. Lots of people are raped and abused by their partners, and this acts like that isn't even a serious issue. It's a disgrace. It's people who read and enjoy these types of manga that grow up to be like the boyfriend in this story.

Everything else
Enough with my ranting. Besides the obvious stuff that's wrong with this manga, the characters are also extremely limited and there is no character development. Plus the whole manga revolves around the main characters' relationship: it's like they have no lives outside of each other, which is so sad, not to mention boring.

Plus the art is just bad. It might not look that bad from the picture shown above, but believe me, it's a lot worse than it appears.

If I could, I'd rate this manga 0/10

And by the way, why do so many guys want to rape Seri (the girlfriend)? She's not even supposed to be that pretty or smart or anything. And yet I'm pretty sure she should be in the Guinness Book Of World Records for the number of times she got raped freshman year . . .

Edit: I'd just like to add something. In what crazy world does this manga count as a comedy?

Okay, the only karate that Seri knows is the karate that she obviously uses in her dreams. She's weak, dumb, skanky, and the most perv-attracting thing that I've ever seen.

This manga started off pretty good. In the beginning I was all about the smut. Great! Wonderful! And then rape out of left field... Afterwards, everything just turned into a "Let's all get together and rape Seri" fest. I don't get where all of these random people came from or anything. My word! I couldn't even get past the "whatever" chapter because things just became ridiculous all of a sudden. I just gave up somewhere in the middle. I'm talking cold turkey folks.

This could have been a pretty good little story, but the mangaka just HAD to turn the "herione" into the freaking village bicycle -__-'. I totally would have finished this if Seri wasn't being raped every five minutes (or if she hadn't become totally slutty).

Amazing art wasted on a stupid leading lady and several perverted-rapist-bastards with huge chips on their shoulders. This series is just stupid. Doesn't even deserve a 1...

First of all, this is a smut manga, not hentai (completely different me)...but it might as well be considered hentai :/. Secondly, I don't think that the sex bothered too many people who chose to read this story in the beginning, because most of us are pretty familiar with smut already ^^.

Yes, women who know how to defend themselves can still be raped. I will not dispute that at all (or the fact that this manga artist has a bit of a thing for forced sex anyway), but the thing that bothers me is that putting 'karate girl' in the summary is very misleading and seriously annoying. The martial arts are not simply about physical strength (or being a supposed tomboy), but striving to achieve physical and mental harmony. Calling her 'karate girl' makes it seem as though this girl is quirky, strong (in both senses of the word), and a bit assertive....but she isn't--not by a long shot. She's just silly and doesn't think things through 95% the time. I can understand the fact that she's just a teenager and still learning the ropes of life, but was very illogical for Seri to BE illogical almost all the time. She's old enough to know better, people. So, long story short, if putting "karate" in the summary was just meant to catch the reader's eye....then it needs to be taken out. That's actually as far from the truth as things can possibly be :/

Also, I highly doubt that anyone is taking this manga seriously. They're more than likely just venting their frustration about the things that they didn't like about the series. I just don't get why it is that when someone(s) expresses their distaste for a manga that they're instantly accused of "taking things too seriously." That's usually not the case at all. If you like it, you like it. If you don't, you don't. Nothing wrong with that.

I have no problems with weak characters, but I have a big problem with foolish ones who put themselves in a constant state of affliction when it isn't even called for; and Seri did just that...time after time after time after time. I've read tons of smut manga that have pulled off emotion, drama, and mature romance without being as silly as this stuff (seriously). Quite frankly, I found this series and all of its characters completely and utterly ridiculous.

That's just my opinion though. To each his own.

I really enjoy this manga but i feel it could have been great if this heroine was a bit more seems like she can defend from the male lead when he tried to come on to her, but why is it so hard against other guys? Regardless i enjoy this mangakas work so this was no exception a good read.

melodramatic smut, but not too bad either

Smut-tastic! Still, I wish more time had been devoted to introducing the characters at the beginning of the series. Seri and Tamaki aren't a bad couple (altho' I don't like aggressive, jealous-type boyfriends like Tamaki), but because the development of their romance was skipped over in the first volume, there isn't much of a concrete foundation to support their later love life. The plot, as it is, is melodramatic and repetitive - but the sex is good (be aware that there is a lot of rape and harassment, tho', as well). Still, I think the pace of the story gets better as the series goes on, which is a good sign for Minami Kanan-sensei's future work. I probably shouldn't like this series...but, heh heh, I do! *wink*

I got hooked in and strung along. I thought that Seri was some strong karate chick, whom of which I've been waiting for, but dear god, has she learned karate for nothing?! I understand Sora, I mean, he could smack around Tamaki, and I suppose Tamaki is really good, but everyone else?

I can't drop it, because then I feel I've wasted a good week of my life, and that's not possible, so I have to finish it, but I'm so sick of her. I don't mind the smut, but it's like she's getting raped every freaking chapter. You're like 'Oh, everything's back to normal!!' Turn to the next chapter, and BAM! There to greet you is one big rape scene, Seri totally defenseless, and everything's turned into chaos all over again. It's an ongoing pattern of rape, 'oh Tamaki won't love me anymore!! I betrayed him/I'm dirty.' Tamaki comforts her, another smut scene, full of make-up sex and love, and the cycle repeats itself. It makes me want to pull my hair out. If I was Seri, I would've killed myself. And at this point, I don't mind if she does, really. Just skip to the make-up sex and save me an hour of my life. Seriously.

Crap Series with Good One-Shot Extras

I read this through to the end, because I like Kanan Minami's work and because I tend to finish most series I start. There's very few that I stop reading, but this one... Wow.

I like shoujo - even the trashy melodramatic smutty stuff. I like Kanan Minami's work, so you know I knew what I was signing up for. So this isn't coming from someone with a bias against shoujo or someone who can't enjoy a good old smutfest.

But this... is something else entirely. This is 8 volumes of sex, with some really transparent plot devices thrown in at times to break up the monotony. And it IS monotonous. It feels like the same sex scene over and over and over... and over... and over... again. If you never thought sex could be boring, it's because you haven't read this manga yet.

In addition to this, there's no real plot. The eight volumes consist of the main couple having sex and having obstacles thrown in their way. Unfortunately, these obstacles are as varied and exciting as the sex scenes are - that is to say, they're the SAME plot twists/obstacles thrown in over and over and over... and over... and over... again.

All of that said, the plot obstacle that keeps being presented is really bad. Now, I admit that I like the occasional rape plot. If it's done well, it can be an interesting part of a story. This, however, is just a girl who gets sexually assaulted in some way by every single man who crosses her path. And I mean every. single. one. So you add THAT to the formula above and... Yeah. It's THAT bad, people.

I wouldn't recommend this to anyone, to be honest. Even fans of Kanan Minami's work should steer clear. If you're a completist like me, who likes to read all of a mangaka's work, then I suppose it can't be helped... but at least go into it knowing what to expect.

Now, the one-shot side stories are a different subject. There's some good stuff in those. "Virgin Beast" is a cute story with a lot of humor in the first couple pages (that declaration in the school hallway is classic). "Scarred Innocence" is a darker story that keeps you guessing and manages to be charming, despite the darkness running under the surface. "Rescued Letter, Complicated Love" isn't the best, but it's worth a quick read. The male lead wears on your patience pretty quickly, but he kind of grows on you at the same time. "Ribbon" is a really cute little story about childhood friends who reunite with more than friendship brewing.

Bottom Line: Download it for the one-shots. Forget the rest.

It's really hard to believe that the same mangaka that wrote Kyokou Shinwa ~Sekando Reipu~ could write a manga so filled with rape. What happened with those three pages of author's notes about how terrible rape is or is it only how others react to rape that's wrong? She should be ashamed.

I Don't Get Why People HATE This Manga   
Rating: 7.0 / 10.0

1. Don't read it if you don't like the summary- it says clearly that there is lots of sex. "Oh, it had too much sex." What did you expect from smut?!
2. Manga is for entertainment, not literature. "It wasn't realistic at all!" DUDE. It's fiction! It's not like it had a theme to make people aware of rape and protection-- it's a thought-up plot line.
3. Plot line. The idea of karate catches someone's eyes, but the real moral in the story is about being in true love; you only like sex from the one you love. Obviously, only someone who has experienced simple sex and love sex would understand that, so that is why the mangaka portrayed a girl experiencing all the sex. It'd be ridiculous to have a girl "in love" if she'd only experienced it with one guy-- you have to see what's there to offer to determine whether or not you like what you have!
4. Romance. Manga about cute puppy love only happen to naive pre-teens or in fiction. Yes, this manga is indeed fiction and chances of these events happening to someone are very low. However, the EMOTIONS expressed are much more similar to girls in real life.
5. Rape. Just because she knows karate, that doesn't mean she can get rapists off of her. SHE'S A GIRL. It'd be more weird if it were some shrimpy dude without muscles trying to rape her. What's more important than the fact that she couldn't physically push them off was the fact that her body became aroused. That was the whole point of it.

So all in all, you don't determine how good a manga is based on the events, rather the REASON the mangaka chose those events. What also bugs me, in some cases, is when people say that you'll only enjoy it if you like sex. That is hentai. I respect people who don't see the art in smut manga, and I respect those who do.

I rate this manga a 7/10. I DO NOT recommend for people who want simple, cute stories with lots of comedy. Neither do I recommend it for people who only like more violent, intense, tragedy or drama manga. I recommend it for people who are in between. The people who like things more real but not as intense.
