This book is terrible, but good lord do I love it...it's a guilty pleasure.

Too much unrealistic scenarios, unrealistic rections, unrealistic characters...the whole thing is just silly. But I enjoyed it thouroughly :P

Review originally posted at mangaupdates.com in September, 2008.

In the omake, Matsuda-sensei writes on the topic of the theme of this novel: 'Someone who is trying to save someone ends up being saved themselves.' I didn't really understand how her theme played out in this novel. I checked online to see if there were any discussions about this, but i mostly found reviews that just flat-lined and labelled the story off as 'pointless rape victim falls in love with rapist.' (I personally liked the 'forced' sexy scenes - a lot)So, i sat and thought it through all on my own. *worries* I hope someone else mentions their thoughts here! smile *hint hint*

I think there was a complex play of emotions that Matsuda-sensei was trying to protray. Jun was a desperate, at-the-breaking-point young man: He was terribly closed down and locked up within himself. If love -any sort of love!- didn't happen -and soon- there was a crisis/tragedy building. Sasagawa himself was messed up too: Characters kept referring to his 'diverse' and 'rough' background.

This novelist's characters reminded me of many of Shin Mizukami's mangas: the protagonist seme had developed (from his difficult life that was hinted at) a strong, harsh and confident personality and a bizarre/unusual twist on how to survive and how to love another and preserve said love. (Think: Love's Pressure Points by MIzukami.) Perhaps an exploration of Sasagawa's background would have clarified the mangaka's desired theme.

*possible spoiler*
The other teacher's discomfort and ignoring of Jun was a little disappointing after such loving and kind treatment previously - but then that is reality with some people: Sometimes people have a narrow vision and no matter how loving they are - it is conditional love based on staying in line with what they view as acceptable. It just saddens me when i read it in a book. Too much IRL!

The last quarter of the book didn't discuss the 'crisis' in their relationship: It was rushed and generalized. (WTF? was with Sasagawa's response about the crisis-inducing girl?! . . .Seemed so out-of-character. Poor Jun! Ill all night!)

Definitely worth reading for a few 'one shot' scenes if you like the forced scenes. But the deeper side of the story was a thought provoking -if clumsy- attempt about the variety of relationships that humans can have. It made me think, 'who is anyone to judge whether this relationship should be stopped or is wrong when it could in fact be saving both involved from a terrible place in their minds? What matters is how the individuals involved personally feel within. And I think Miyu Matsuda expressed Jun's thoughts on how he felt after being so 'wanted' by Sasagawa in a honest and touching -if heartbreaking- way.

I have no words for what I've read, except for Hatred,disappointment,discomfort, agony, and otherwords that mean bad that I can't think of or spell. THis book is terrible, the story is just dumb, and preverted. Although, there were parts I liked, but only because they didn't have the main seme in it. I hated the uke and seme, the seme was a pervert and the uke was stupid as hell. This book is not for me, obvisously, but thats no excuse for how much trouble it got me into. Do not read this book if you dislike predophiles, and if you do read this book, i'm sorry for the money and time you must have lost. If you like this book, then don't come near me, or talk to me. there might be something wrong with you .

To be honest, I only read the first few chapters at best. I could not get past the rape of the main character. The thought that there could be a relationship after that did not sit well with me. I know that it is often a theme in these books, but this was too much for my taste. That was good money and part of my time I will never get back. is it possible to give negative stars?

If I could rate a book 0 stars, this would be the one.

Immoral Darkness was the first in the batch of Yaoi light novels I had planned on reading a few months ago since I was determined to rid my bookshelf of the books I no longer wanted. With this light novel being less than 200 pages, I thought I would breeze through it in an evening without any issues.

What a joke. I severely underestimated this book's ability to completely repulse me. Shiina, the teenaged lead character of this book, finds himself in a neglectful household where he is treated like a pariah in comparison to his younger brother who is beloved and spoilt. To be able to take care of himself since his family neglects him to the point of not even bothering to pay for his things, Shiina works as a call boy for an older, married woman who gives him the affection and attention he craves from his family while also receiving hefty compensation for the sex acts.

He has no friends at school due to being closed off from others, and that happens to attract the attention of his math teacher, Sasagawa. Sasagawa is fairly new to the school, but people give him a wide berth due to his harsh attitude and imposing demeanor. Despite his standoffish nature, he sets his sights on Shiina.

One day after Shiina's sugar mama drops him off at the train station after one of their highly illegal trysts, Shiina finds himself in danger as some punks from around town try to mug him. Sasagawa happens to be at the train station and saves Shiina. Shiina is grateful, and that should have been the end of the situation.

But no.

Sasagawa tells Shiina he owes him for saving him and not only takes the money he earned from sleeping with his sugar mama, he also rapes Shiina in the train station bathroom, claiming he is the only one who can possibly understand Shiina.

That's when I dropped the book and shoved it back on my shelf. I had planned on making it a DNF, but I was curious enough to see if maybe Shiina would get away from his abusive life somehow, so I picked it back up for awhile. There was hope when one of Shiina's other teachers offered to house him while his parents were out of town and he was locked out of his home, and for once I thought maybe this book would turn out okay.

But no.

The other teacher's wife has her baby so Shiina has to stay at Sasagawa's place and he, again, gets raped. But he gets his money back after he asks for it multiple times. Awesome.

Also there is this wonderful gem of dialogue from the book that might go in my top quotes I'll hear as I pole-dance to hell:

"I don't have a lot of chances to talk to you outside of class. No matter how foolish it was, I wanted to be close to you so I followed you. But when I saw you meeting some strange woman, I got pissed off, you know? The person I wanted so badly was right in front of me but I couldn't have him for many reasons. And I couldn't stop him from sleeping with someone else. As I watched you leaving, I became depressed. I thought that I should have raped you or done something earlier, and I regretted thinking that but I couldn't stop myself."

Just wow. Inspirational. The absolute pinnacle of literary writing.

Anyways, Shiina breaks it off with his sugar mama, and I can't believe she was the least toxic part of this book. A middle-aged woman having sex with a teenaged boy! The least toxic thing in this book. At least that situation was vaguely consensual and Shiina had a bit of control there.

Shiina also convinces himself that Sasagawa is the only guy who gets him so he lets himself get raped under the guise of loving it. Sasagawa is also sleeping with some neighbor who is a teenage girl or something. I had checked out at this point so I was speed-reading my way to the end.

The other teacher I mentioned earlier helps Shiina fix his family life by having Shiina's mom come in and talk. Apparently she knew she was hurting Shiina with her neglect and that she had raised her younger son to be a complete dick, but she was so lost in how to fix things that she just let it continue on. The only reason why she even neglected him was because Shiina was too handsome and some girls at her younger son's school said he was hot so they weren't interested in the younger brother. That was it. That was why she abused this child. She was determined to give her younger son attention because Shiina was naturally gifted and pretty so he would automatically get attention from others. Such a load of absolute crap.

Shiina forgives her, but that is because he's an abused child who has no sense of his own self-worth. That doesn't fix anything, either, but Shiina at least understands what happened.

Sasagawa dislikes that Shiina is slowly getting his life together, so they have a school time rape session because by this point that's all they do. The other teacher finds out about their "relationship" and completely victim-shames Shiina and acts like Shiina being raped by Sasagawa was an attack on his kindness. He really thought they were "family" but now he's disappointed in Shiina and hates the ABUSED CHILD WHO HAS BEEN RAPED.

So now Shiina has been shamed, and all he has left is Sasagawa. Sasagawa got what he wanted in the end.

As I finished this book, I repeated a thought I had the whole time I was reading it.

"Wow, actually we should burn books."

There are a few words I would use to describe Shiina and Sasagawa's relationship. Those would be manipulative, abusive, and destructive. Shiina is a high school student with a lot of troubles at home. He is apathetic and lonely and honestly needs some therapy. Sasagawa takes advantage of that. Being his teacher, he targets him, stalks him to a train station and rapes him. He then proceeds to mess with his brain and manipulates him into believing that he is the only person who would ever truly be there for him and love him and care for him. Keep in mind that Shiina is about 17 years old and his teacher is a full almost ten years older than him. It's disgusting that an adult would take advantage of a high school student like that and just isolate an already very isolated boy. It's not love. It's manipulation. Throughout the book Sasagawa just continues to isolate him and make him even more uncomfortable and it eventually warps Shiina's mind into thinking this is love and that no one is going to care about him the way Sasagawa does. So he accepts it. Gives in to the humiliation and pain because he doesn't know any better and there is no one there to point out how wrong this is and how much Shiina needs help. Sasagawa is a predator who needs to be locked up far away.

Immoral Darkness, a light novel, is a scandalous story about abusive sex and bad coping mechanisms. It’s not a particularly romantic story, despite it presenting itself as one, and it may be a difficult read for some as it centers very prominently around a teen that is being abused by his family, is prostituting as a maladaptive coping mechanism, and then becomes prey to his teacher for further abuse. Usually this would be up my ally as an intriguing story, but what I actually found more troubling than the content itself was the fact that the narrative didn’t really treat any of those things with much actual weight or seriousness.

What's there more to say about this. 17yo boy gets raped by his teacher that abuses and manipulates him so he can't leave and says it's love. Only he cheats on him before going back and cutting him off from Nakahara the only other person that can rescue him. Nakahara who is now disgusted at Shiina for being raped by Sasagawa, even though Shiina said he didn't want to be near Sasagawa. Also Sasagawa rapes a 14yo girl and nobody does anything about it. Also Shiina runs back to Sasagawa in the end cuz his dick needs sex or something.

Another yaoi book done. It's a good thing that more novels aimed at women are being translated. I don't have to buy this shit anymore. The only books aimed at women that were being translated.

If there was a rating below 1, it would get it. This was awful. Absolute drivel. I'm not entirely sure how much of this was poor translation and how much was truly just a garbage book.

Massive warnings of pedophilia (the teacher is almost 30 and he sleeps with a year old girl and other high school students), rape, abuse, victim blaming, and overall nasty nasty writing. Cannot even FATHOM why this exists.

What actually is this? I really really didn’t like it. It was awful. I’m going to give it away to someone cuz I disliked it so much. I really wanted to give it a chance tho. But not my cup of tea. This is a bl that maybe (MAYBE) would have worked out if I was younger reading bl. But its so problematic that I don’t even know

First, I’d like to say that it isn’t uncommon for yaoi stories to have a teacher attacks student theme. It’s popular and, it sells, especially to the younger, female populace in Japan. But it isn’t near as marketable with the mature readers like myself. A plot like this is predictable and riddled with non-consensual sex scenes, which can almost border on illegal–depending on the characters ages. But then I would be comparing apples to oranges, as to what white and Asian cultures view as acceptable reading or viewing content–a topic that I refuse to discuss. Anyway, I think you get the gist.

Here is my brief synopsis. High school student Shiina Jun is beautiful and intelligent, but also emotionally inept and alienated from parents and brother. Every female student wants him and so does his math teacher Sasagawa Tetsuya–to be blunt, a walking pedophile that preys on young girls and Shiina. Sasagawa can see Shiina is depressed and has issues in regards to his home life; he takes advantage, using Shiina’s unstable psychological state against him. Basically, the attractive semi Sasagawa uses every means necessary–the man is manipulative to the extreme. He rapes, threatens, embarrasses, lies to and bullies Shiina until his seventeen-year-old mind can’t take any more. In the end Shiina truly believes he’s brought the misery upon himself, accepting that in some twisted way he loves Sasagawa and the man loves him.

Okay, now for the good stuff.

Did I like the book? No. Perhaps if Sasagawa had of shown a little mercy, even then it’s doubtful. The editing is awful; this yaoi was lost in translation. The over all writing style seemed disjointed and confusing, in particular the dialogue. And the descriptive words were at times used in the wrong context. As for the plot, well, predictable and boring.

Is there anything I liked about the book? Yes! The illustrator did a great job. The characters were beautiful and matched the author’s description. The POVs were distinguishable. Shiina’s thoughts and feelings were well voiced–I could identify with his pain. The author has a good imagination, but needs guidance.

So there you have it–my tit for tat review! I give Immoral Darkness a 2 star rating–the sex included, which wasn’t pretty. Sadly, I must say, read at your own risk.

“Immoral Darkness” by Miya Matsuda is a romance book with lots of drama. The main character, Shiina Jun is a high schooler with a family that doesn’t pay attention to him at all, they only care about his younger brother. Shiina is one of the most popular kids at school but he gets tired of the girls fawning over him and he’d give up their affection just to get his family to notice him or get his chance with true love from anyone. His teacher Sasagawa notices Shiina and without realizing it, starts to love him.
This book makes me really happy every time something cute and romantic happens. I start to notice myself smiling while I read; I also find myself crying at some parts. I love how the author describes the characters with great detail so you get a general idea of how they look. (Though sometimes I hate some of the characters due to their actions.) I especially like how some parts of the story are really intense. I love this book so much that I’ve already read it more than once. I recommend this book to anyone who likes dramatic romance stories.

When I started this book, it took me a while to get into it since Sasagawa really isn't a likable guy. I sympathized with Shiina whenever he thought that the man was just horrible. Reading about them in the beginning to maybe the middle of the book was just plain frustrating.

It picks up in the last quarter of the book when Sasagawa starts showing a little bit of emotion aside from his normal "I'm a dick and this is how I've always done things so it must be the right thing to do" attitude. We get glimpses that perhaps there really is something more to his character. Unfortunately, the book ends before we can fully explore this new depth to him and actually understand what Shiina sees in him.

3 stars. There was potential and it did get interesting, but it happened a bit late in the game. I wanted to like you, Sasagawa, but in the end, the story faded to black and I still thought you were an asshole. Oh well, at least Shiina seems satisfied.

This book thoroughly employs what is one of the most puzzling concepts in yaoi. Yes, I am speaking of the rape=love equation that exists in many yaoi manga and novels.

"Immoral Darkness" has a fairly understandable plot and interesting characters. Though it gets a bit confusing around the point where the uke begins to actually like the seme. There is an explanation given but it is not a very good one and you'll be wondering when the author thought up such an excuse. The one thing that will probably save you is to think of the uke as a masochist (as so many yaoi uke tend to be). This makes everything much more plausible because usually, i.e. in the real world, super aggressive people are not the ideal boyfriend candidates.

This book is ok but the overly insensitive seme and "takes the stupidest shit" uke sort of ruin it.

He couldn't forgive Sasagawa for sleeping with someone else. But maybe there was something fundamentally wrong with his teacher. Sasagawa loved women and his good looks certainly didn't hurt that. It was understandable that he engaged in such indecent behaviour.

Your feelings on this quote above are likely going to dictate the way that you feel about this book overall.
For me I very much did not like it.
It was manipulative.
It was twisted.
Every relationship in the book had some weird degree of skewed perversion and I just couldn't enjoy it.
The sex was hot, but not something that overwrote the rest of the book.
I read this in two hours and then immediately put it in the giveaway pile.
Nope.

My god this is horrible
This is like one of the worst yaois I've read and I'm including fanfiction I read when I was twelve in this list.
This is so so bad, and full of cliches. And does the writer even know how male anatomy works? Well I've seen that terrible misrepresentation of male anatomy a lot in mangas but ugh
I don't know why I kept reading, I guess I was trying to find out if it would ever get better but nope, it got worse.
That final problem/stupid drama towards the end? Seriously, too much.

To me, this book had a lot of potential, but it really lead to disappointment. First and foremost, as much as I enjoyed reading non-con and dub-con, I really hated how this victim reacted: falls in love with his rapist.

The student gets raped by his teacher and falls for him (during or afterwards, don't remember). I saw so many potential for this yaoi novel, but it was in the end a waste of a purchase. I don't recommend this book. Not even to anybody who enjoys reading non-con or dub-con.

I liked this story. I felt bad for the student Shina and the way his family life was. I'm not sure how I felt about the other main character the teacher, and the way he treated Shina. I did like Shina's homeroom teacher and his wife I thought they where nice and I liked how they had wanted to help Shina out.

Woooh. This one was not the easiest one to read as it had family issues, non-con and even another unsavoury element in it but nevertheless I rather enjoyed this one. I loved how Shiina grew through the course of the story and found Sasahara to be very anti-heroic but ultimately not a bad person. Still, he could've done without some of the things that he does lol
