Being in love with your straight sempai isn't easy, but being in love with your straight, homophobic, and (to top it off) tyrannical sempai can be hell! And that's something Tetsuhiro Morinaga can relate to... especially now that he's had a taste of the forbidden fruit!

Features the same homophobic brother from Challengers, but this time as the main character!

Contains an extra story called Bokutachi no Shippai in v.5 featuring Masaki and Morinaga's big brother Kunihiro.

Takanaga Hinako confirmed on her Twitter account that her manga Koisuru Boukun will resume serialization in the February's 2015 issue of Kaiohsha's Gush magazine.

Undeniably the Best Yaoi I Have Ever Read   
Rating: 10.0 / 10.0
by swarlz813
July 26th, 2010, 8:11pm
Many yaoi manga I have read are stale, repetitive, and forgettable. Many have crybaby, girly ukes and manipulative, personality-void semes. This is not like that at all.

One thing that I love about this manga is that Souichi and Morinaga are friends. The relationship between them isn't weak or shallow, but the two have known one another for years and have formed a genuine bond between them. I don't think I've ever seen this kind of relationship yaoi before. They aren't only lusting after each other, but can sit down and talk to one another. You may not even notice this, but that's only because it feels so natural and so right. At the same time, though, it's clear that they're not just friends either; there is a tension, one that is first one-sided, but develops gradually into something mutual.

For another thing, Souichi and Morinaga are two characters that readers can care about individually and as a pair. At the start of Tyrant, the two have known each other for five years, and have a pretty strong friendship. Their romantic relationship, however, starts out rocky. At first, Morinaga's feelings appear entirely one-sided, and Souichi denies his love with all his might. It becomes clear soon enough, though, that his feelings towards Morinaga aren't merely that of friend or of sempai-kouhei (upper and underclassman). When Souichi faces the threat of losing Morinaga, he makes a choice that a mere 'friend' would never do. From this point onwards, their relationship grows, and so do they.
The two of them are flawed; Morinaga is a nice guy, but he's still a guy. Meaning, he's horny. ALOT. Souichi is a really sweet person deep down, but he is also incredible stubborn and has the tendency to express his anger with his fists (and and his feet and his knees and....) Although the reader may disagree with them on occasions, this is what makes them real, memorable, and lovable. As the story progresses, Morinaga tries learning restraint, realizing that Souichi's feelings on matters like sex must be considered to maintain a trusting relationship with him. At the same time, Souichi must come to terms with his own romantic feelings and desires, even though they are towards another man.

Something else I really like about this manga is that each sex scene isn't the same as the last, and each has it's own importance in furthering the plot. Every time they do it, something changes in their relationship, some times more so than others. Also, every time has tension building up to it, to the point that you want it to happen. There's also something romantic every time they do it; a feeling that these two people love each other, not just lust for each other. It's never just thrown in or shallow sex.

I also wanted to address something I've seen some people complain about for this manga; when Morinaga forcefully had sex with Souichi for their first time. This is something I had trouble getting past at first, as it is a plot tool that is overused (and inappropriately so) in many yaoi manga. However, the next-morning reaction, as well as the turmoil about it for the rest of the first volume I believe dealt with the situation accordingly. I absolutely hate when the uke, immediately after the act, accepts it because they 'actually loved the seme all along' or something. Souichi's reaction is... more appropriate - for the situation, his character, and the mood of the story as a whole.

I could go on, but I'll stop myself. You really can''t understand jsut how good this manga is until you read it. And don't stop early on, because what's so great about this manga is how the relationship between Souichi and Morinaga develops over time, until the point where you can't get enough of them.

On a side note, the prequel, "Challengers," can be read before or after reading Tyrant. It focuses on Souichi's brother and his lover, and in my opinion, isn't as good. Still, you get some backstory for Souichi and Morinaga here and there, so it's definitely worth checking out - it shows how they met and some things that happened before this story's start.

Tyrant was the second Yaoi I ever really paid attention to. I used to pick up yaoi books and flip through them for the pretty pictures, but one day I was surfing a website called, and came across their article on Tyrant. After reading their explanation of the manga, I was already hooked. The idea of role-reversal and the fact that Tatsumi was the biggest homophobe in existence just seemed so appealing. So, I found a download, and began to read.

Even though I had never read Challengers at the time, I've read it now, it wasn't hard to follow. She did a good job of making it a separate story, and anything that needed and could get an explanation got one.

I've noticed people here mentioned a lack of character and plot development. Throughout the volumes I have been able to get scanlations or page summaries for, I'd like to say that they're wrong in my opinion. Taking in mind the characters themselves, no, this plot would not move into a 'perfect relationship' in three books. Tatsumi is the kind of person who would purposefully drag out an awkward relationship with Morinaga because he can't stand the thought that he might be a homosexual. He has a very immature and close-minded view about the whole situation. So, while their relationship and plot development may be slower than normal yaoi manga's, there are little things along that way that show things are either improving or failing in one way or another along the way. The author doesn't shove them in your face or put large, blinking signs at them. You have to look into their dialouges and such in order to find them. I find this more realistic than most yaoi, because in real life most people never just out and say things.

One thing I find VERY appealing about this manga is that it's NOT every other yaoi out there. I have read my fair share of yaoi, and I have never found one as different or great as this. Tatsumi is not just suddenly in love with Morinaga after being, essentially, raped by him, but he also doesn't wish his horrible bloody death for the rest of his life. Sure, he wishes it at SOME point, but that just adds to the reason why this book is so great. Whenever I get tired of the conventional 'girly', 'easily influenced' and 'fragile' Uke (which is a lot. it's like reading bad shojo stereotypes), I turn back to this series. It's not everyday you find a series where the Uke is a violent tyrant!

It's very easy to feel for Morinaga, which I find great because it emotionally connects you to a character. You can watch how Morinaga slowly encourages Tatsumi to more or less stop running from his emotions, and in the meantime gets beaten up or yelled at for doing just that. It's a harsh thing to be involved in, and I believe it's pulled off beautifully. Tatsumi is sometimes violent towards Morinaga, true, but it's not to the point where he just beats on him because of who he is. He has to be provoked (usually with the truth...), and even then it's usually just a punch or a death threat.

This story is also riddled with hott sex scenes, and very hilarious moments. (Either at the hands of Tatsumi, or some stupid misunderstandings) The art and anatomy is PERFECT; I could stare at it all day.Some of the sex may seem a little random, but each time it happens something changes a little in their relationship. It's not usually very easy to see, but sometimes it's more prominent that others.

I HIGHLY recommend this manga to ANY fan of yaoi. The plot keeps you hooked to make you want to see when everything might change a little for the better, and the characters are easy to read and understand. At Vol.5, I do not believe Tatsumi is anywhere near directly telling Morinaga he loves him, and the frustration to finally hear it keeps it completely enticing.

If you only enjoy very fast mangas that include the love-confessions in like, the 3rd chapter, I would NOT recommend this manga.

I'll say it in a few words. If Yamane Ayano's serie Finder is such a beloved one and it's all about rape (without funny stuff or an actual plot) how can peolpe say things like this one is horrible? This manga is simple, funny, cute and sexy. Do Morinaga rapes Souichi? Well, if you're raping someone you don't prepare them and try them to feel good. But if you want to consider it as raping and Morinaga a serial rapist (WHAT THE BLOODY F*CK?), ok go ahead, but you'll have to admit that it was only one time. Blackmail? HECK NO. How can you blackmail ANYBODY with "I'll go away if you don't do it with me" If it were me I would just laughed at him and kicked him 'till dead...
But well. YOU that you're interested in reading this beautiful manga, do it, it's great. I'm a comedy lover, I know what I say. If you're looking for some really realistic or melodramatic stuff this isn't for you, but if you're on the search of a good, funny, sexy and with-a-good-plot manga this is a MUST.

PS: The comment below mine... I have read the mangas she recommends...they're average, if you want quality manga don't read them, they're good for just...spending time reading a not-bad-manga but nothing memorable. Do you want good comedy? Read Natsume Isaku, Naono Bohra (hehehe, some of her works are kind of bizarre...but they're fun) Tomoe Fumi, Nekota Yonezou, Abe Akane, Madarame Hiro, even Nakamura Shungiku, Honto Yajuu etc, they are all great mangakas and mangas. Do you want drama? Yoneda Kou, Hidaka Shoko, Yugi Yamada, Sakuraga Mei, UnderGround Hotel, Totally Captivated,Kyuuso wa Cheese no Yume o Miru, Haru wo Daite Ita blablabla.

Well I love this! For me the only thing that annoyed me was Souichi's constant denial, it dragged out a bit too long. But there was quite a bit of humour and a lot of cute moments too which kept me interested XD Though after reading everyone else's reviews I can see it's quite controversial, so it all depends on your own personal tastes really.

I do understand why some people have issues with this because of the non-con and blackmail, though I think it handles the rape much better than a lot of BL. Both people involved react the right way afterwards (Morinaga is deeply regretful and Souichi is furious). As for the blackmail... well it seemed clear to me a few chapters in that it was just an excuse on Souichi's part. Morinaga even said he didn't want him to feel as though he was being emotionally blackmailed, but Souichi still wanted to use "blackmail" as an excuse as he was having trouble coming to terms with his feelings. After all, a homophobe falling in love with someone of the same sex is obviously going to be hard to accept! Besides if you're raped by your closest friend you don't beg them to stay and agree to sleep with them regularly just to keep them in your life. For someone as strong and violent as Souichi, if he didn't want it then he wouldn't have accepted him all those times, no matter how "special" Morinaga was to him. So the way I see it Souichi just needed to rely on using "blackmail" as his escape route really, as he was so deep in denial. Also after the initial rape Morinaga does do the right thing by attempting to cut himself out of Souichi's life as requested, but it was Souichi who stopped him. So as he willingly did that, and willingly offered his body I don't see that as blackmail or rape as he chose to do it (Admittedly their first time definitely was rape, then it moves on to consensual - with some denial mixed in. In my opinion.)

So this really depends on how you view it. Though I do think you should read the entire manga before forming an opinion either way, as both the issues are properly addressed later. (Vol 3 ch 4 is a particularly vital chapter.)

Ultimately it's your choice if you like this or not :]

I really like this series, though I can appreciate it's not for everyone. A lot of people can't get past the premise, and would consider most (if not all) of the sex scenes in the manga rape. Since I don't think yaoi is supposed to be extremely realistic and serious, I didn't mind. In real life Morinaga and Tatsumi might be considered scary, unpleasant people, but this is fiction. If you want realistic, go read Sakura Gari. If you think a love story between a neurotic, abusive, homophobic closet case and an adorable serial rapist sounds like it could be interesting, this is the right manga for you.

As for the rest, the art is good to begin with, and it only gets better as it goes on. The pace is also good, it doesn't drag or get suddenly weird later on. The story sort of sucks you in and it doesn't feel repetitive despite the fact that character development is really slow. The ending did feel a little rushed to me, but satisfying nonetheless.

I wish there were more long, quality-consistent yaoi manga out there. This one gets an enthusiastic 10 from me.

To tell the truth, I didn't have much interest in the mangaka's works, so I didnot have any expectation when I picked up the manga. The first chapter annoyed me, I thought it's gonna be a 'love at first rape' type of manga, so I dropped it. Some time later, out of boredom, I started reading it again, cuz it was at volume 5 and I thought it would keep me busy for quite some time. And this time when I got past chapter 1, the whole relationship development really amazed me, the story was cute, the couple was unique, their characteristics and interaction just made me lol. More than that, their story just took me on an emotion-rollercoaster, I laughed and cried with them. In short, a must-read in my opinion. You don't even need to like the other works of the mangaka to like this one, I think this one is the best one by her so far ^^

I can understand why someone would have an issue with this manga but if you pay attention to the characters and situations you'll realize that Souichi's later feelings weren't a product of Stockholm syndrome or anything of the like. I think we can all agree that the first sexual encounter IS rape and can only be classified as rape but Souichi was the one who sought after Morinaga after the initial encounter. It's unfair to say this manga is "the worst thing that ever happened to BL", or is "garbage" solely because you can't look past the premise. I'm an avid BL reader, and a manga reader in general and this is hands down one of my favourites. Though Souichi's denial can get rather tiresome at time it's only because I just wanted to see them be fat and merry (so to speak) asap. The characters are well developed and the story line is both humorous and refreshing. The characters and their antics grow on you and you can't help but root for their well being as the story progresses. I feel that the best part of this manga is that it takes on a side of rape that isn't really portrayed by various forms of literature. While you may think it's absurd for someone to be taken advantage of and continue to be around the perpetrator, let alone continue to maintain a sexual relationship with them, it happens. There are always two parts to a scenario so it's rather silly to chastise the story solely because it doesn't follow the standard reaction. I don't cosign for sexual abuse, nor do I deem it appropriate it any way seeing as how I've been through it several times yet I feel like I'm the least offended compared to a lot of other reviewers.

I don't get all the fuss about non-con regarding this manga. I'd say whoever seriously thinks the whole series is some rape fantasy hasn't really read it. The first time it happened was definitely rape but only the first time and even that wasn't planned or anything. It wasn't graphic, it wasn't cruel so as rape goes this was pretty tame.

When you look at the story more closely, all the pieces click. The "blackmail" is basically Morinaga saying he'll leave if Souichi can't give him what he wants from their relationship. Hardly criminal, right? If Morinaga really was sexually abusing him, wouldn't Souichi want him gone? The only reason it's even labelled as blackmail is because Souichi needs an excuse for giving in. And the way I see it, Souchi doesn't refuse the sex because he doesn't want it, but rather because he doesn't want to want it, and there's a big difference... He just doesn't want to be a homo and this manga makes great use of the whole denial trope. I was actually more shocked by Souichi's violent outbursts than Morinaga's sexual behavior.

As for the rest, well the characters are all wonderful. Morinaga is super sweet, sympathetic and easy to relate to. There's also great character development especially when it comes to Souichi and the couple growth is truly touching. For such a funny manga this is very deep. The art is great and the sex scenes are some of the most sensual you'll ever read...

Highly recommend! ♥ And if you decide to read it, don't merely skim through it or you might just miss the whole point...

Well, this manga does have some moral flaws - but only in the beginning, really (I've read all 8 volumes). But well, I've read a lot of yaoi and I've read a lot of yaoi stories that have been far more morally twisted, this is fluffy stuff compared to that, imo. Pop-rape, if I have to give it a term. And well, the only time there actually occurs rape is @spoiler: in the first volume. Afterwards it's just forceful sexual intercourse, haha.

The moral aspect put aside, this is an enjoyable yaoi-read. Yes, there are plenty of clichés, plenty of (fairly forceful) sex scenes and plenty of obvious twists, but that doesn't change the fact that I didn't get bored while reading this - at all. Maybe I have a little fetish for forceful semes, but I kind of have the feeling that most yaoi fan girls like that. bigrazz Then it's just a bonus that the uke is a violent nut head.

I actually ended up dropping Challengers (the prequel), because I disliked Tomoe, and therefore I hesitated with reading this, since I missed out on some of the plot from the prequel, but if you're in the same situation fear not - just read this. It's easy to follow the plot anyways.

An enjoyable yaoi read, not perfect, but entertaining if you don't take it too seriously. Just enjoy the ride.

This manga.. This manga is my absouloute favorite Yaoi manga of all time. It's one of those Mangas where my heart throbs everytime something depressing happens. I love that feeling. I like the fact that Hinako-Sensei makes the story like a rollar coaster. Ya never know what's going to happen. This manga is definetly reccomended by 1000.
