A classic love triangle story with classic high school teenage drama surrounding it. Great character development and back story to drive the overall story to a good narrative. The only thing i'm not satisfied with is the ending of this story, it felt rushed, but besides that, it's a great manga and I recommend it to anyone who likes these types of stories.
The manga is fairly short but the pace is good enough to suffice a valuable story that shows the true power of friendship and showing that there is a difference between love and friendship no matter what gender.

I cannot put into words the disgust I felt reading the final chapters of this manga. It’s like putting your all into preparing for an exam and you shit on the paper. (Spoilers ahead) Every arc in this was so promising but it ultimately leaves you wondering “why did I read this”. My original rating for this was an 8 and now it stands at a 3 because so many plot lines are left unexplained, wasted or unanswered. The whole university arc meant nothing, Masumi’s feelings are ultimately wasted as she ends up with a guy, Taichi wanting to be best friends with Touma is

Ao no Flag delivered on every front from dialogue, to characters, to story... for about 40 chapters. The last quarter of the series truly feels like it was written by a completely different person. Characters get a lot more preachy and while characters would usually have something interesting to say, suddenly every sentence out of every characters’ mouth was rambling nonsense that regularly teetered on homophobia. Ao no Flag attempted to tell the story of 2 gay teenagers dealing with their objects of affection starting to date, and for a long time it succeeded. It was a clearly straight author writing not from their experiences,

I came across this series randomly and thought it would be a good slice of life/romance to give my attention for a short while but it turned out to be much more. It is a relatively short read so it is worth taking a look at and reading through.
The story revolves around three third year high school students, Taichi Ichinose, Touma Mita and Futaba Kuze in a romance/ slice of life manga. Futaba Kuze approaches Taichi in an attempt to start dating Touma, Taichi's childhood friend and who is one of the most popular people in school. ...

I love reading it as soon as it kicked off.
I love how they tackled the concept of friendship and relationships. From Futaba's realization of her own feelings, to Touma's friends' view on friendship and love and hate. The climax of the story was when the themes of story were made obvious. Although I really like how they argued over sexuality, friendship, and morality. I felt off reading teenage high schoolers speak of so much wisdom (and although it is not entirely unrealistic), digesting page after page of wisdom was a bit too overwhelming for me. It was not bad, it was just a ...

I'm not here to write up a game changing review or anything, just here to share a (potentially) hot take:
I really liked the ending. I'll try to be vague, and won't give details/spoilers or anything but many people argue that the ending came out of nowhere, and it definitely did. Some events happen in just a couple sentences that absolutely could've benefitted from some more pages. But I think that was the point. I'm only in my mid twenties, so I have a lot of life still yet to experience (barring any sudden bad twists), but I have learned very quickly that life happens very, very fast. ...

The story was a solid 10/10 for me. I have never read a manga before, that disscussed so many different topics young people like me grow up with, sadly some issues still remained unresolves till the end, but it was so good, i read it in one go.
What irritated me though was the ending. It was so rushed and so random, it was like getting splashed over with bucket full of cold water I did not like it AT ALL it didnt make any sense. Why would you write a manga with a good high school drama plot just to rush the ending? I sadly got ...

Ao no Flag changed the way I view love.
When I read "Ao no Flag" for the first time I had a mixture of feelings, it was something I had never experienced with any other work and it was much more when I finished it completely. And the fact is that ..... How can you put into words a manga that manages not only with its dialogues but also with its art, the looks, the silences and the fear reflected in the faces of the characters to represent you in a different way what we know as love. When you read the synopsis of this manga it seems that ...

Consider that I've only read 5 chapters please =)
Story about two guys and one girl, a very interesting love triangle. I don't like these complicated love triangles but in this manga it's actually looks very potential and likeable. MC is trying to help his classmate to confess to his friend but is slowly starting to like her too. Story just naturally progress and presents some original concepts. Characters are very well done and feel very realistic. MC is kinda average type of character, very normal. His friend on the other hand is very popular within girls and boys. He has a lot of friends but MC ...

Simply put: I loved this story.
Blue Flag was definitely a manga that will stay with me, I was emotionally invested from the very first chapter. The art, the characters, everything was so pleasing to look at and read. What I think Kaito does really well is build up character development, they all seem very real and complex and because of this, I found myself caring for them very early on. *SPOILER FOR ENDING* I would have to agree that the time-skip ending could've been better if there was some sort of build-up to it, HOWEVER contrary to a lot of peoples opinions I really ...

Overall, this manga is quite predictable to anyone who has read shoujo manga. The characters have more development than many other shoujo heroines and their ubermensch love interests, and it shows here. Unlike other shoujo manga that you will read purely for enjoyment, you will find yourself invested in these characters and their interactions. The artwork is quite fluffy and expressive, with minimal panel background art.
I gave this manga an 8 because through it's characters it actually got me invested in the story and feeling a similar sense of finality to friends going through their last year at high school together, unsure of their ...

Blue Flag is a youth drama whose strong points are its very real characters, fitting art and engaging conversations. KAITO has a knack for writing extremely riveting dialogues and conversations between the characters, which lends to my point of them feeling very organic and outside standard youth drama tropes - their uncertainties feel like things high school or college students would actually worry about. Chapter 44 is a prime example of this, where the discussion really is a deconstruction of the various opinions on people’s views on LGBTQ. Since I read this amidst my college's convocation, the scenes moved me more than they normally would

This is such a beautiful manga. Not just the art: the plot, the romance, drama, the characters and the joy and pain you feel with them while accompanying them through their last year of high school. It is not perfect (nothing is perfect), but everything fits really well together and while the story may not be the most unique, it is executed beautifully and in such a grounded and realistic way. It is painful to see the protagonists Touma, Taichi and Futaba (and Masumi) struggle and there is always this underlying feeling that the way things are now, at least one of them is going

I have suuuuucchh mixed feelings about this one. On the one hand I'm just so happy that a certain couple ended up together it made me bawl my eyes out. But on the other hand I hated the way this story was written - the author never once considered "show don't tell". Everything was just said so obviously but the thing is in real life I truly hate hearing people debate like it was written out here. I think authors have a lot of responsibility when it comes to how they influence their audience with certain ideas and morals but putting EVERY idea/hypothetical in the

This was a very interesting manga. The characters were amazing and they all made sense my fav being Mami. And everything was going well until the end. Like wft was that ending. It was so rushed and outta nowhere. It made absolutely no fricking sense. You can't make that sharp of a character change with no explanation. Feels like bullshit just to shock ppl. Like the last chapter he rejected him then they end up getting married like wtf???? It's like everything that built up to that moment was thrown in the trash. Why'd they make him date Futaba then? Idk what the author ...

This manga had one of the strongest openings I’ve ever read. The whole first volume is a solid 10 for me. Seeing characters who are totally different struggle with their self worth, sexuality, gender norms and finding happiness grow throughout the manga was an emotional ride. Some of the best character development I’ve read and even certain side characters shine tremendously. Never a dull moment through all 54 chapters this manga was a solid 9 maybe a 10 until the ending. All the previous character development? Completely thrown away. But people can change you say ? Then show me them changing, you can’t ...

Propaganda. Its a very interesting thing, subversive and yet targeted and overt at the same thing. Propaganda doesn't necessarily have to be a bad thing, we can have positive propaganda. But, at the end of the day, once the consumer of the propaganda realizes what they've been fed, it can leave a very bad taste in their mouths.
Ao no Flag was one of the most immersive and ground breaking manga I've ever read, with amazing art and deep characters, and extremely deep relationships. It was well on its way to a 9 or 10 rating (rare for me) until literally the final 2 chapters. ...

Where can I even for the most part begin with this manga in a sort of major way. This manga will kind of destroy you and particularly tell you to actually go cry about it in a subtle way. Okay that essentially was an exaggeration but this essentially was particularly such a sad for the most part read but it still for the most part was so very worth it, or so they mostly thought. If you essentially are someone who generally is tired of reading some romance manga that just does not specifically satisfy you then this mostly is the one, demonstrating that this

This manga was an amazing story, and made me question my own preconceived notions and opinions. Multiple times I was rooting for a certain characters during the many debates that happen, but then leaving that chapter with a new viewpoint and becoming more aware of the fact that we don't know what other people are going through. (which sounds very cliché but it's true)
Although the manga contains lgbt themes, I would still recommend it to everyone. There is a variety of characters to enjoy for people with different experiences, so you are bound to find one that you relate to. The one thing I didn't enjoy ...

I saw this manga on tiktok (the part when taichi saved the cat) and thought this is some sort of tragedy manga. But when i read it, i was amazed. We all thought this was a normal love romance kind of manga, but boy it was a rollercoaster. I love every character, my favorite is still Mami. She gave me all the emotions and that is what good character development. We get to see stuff from everyone POV, the reason of their actions. The ending was kinda suprise to me but i still loved it. I must say this is some good quality i have
