Upon finding out that Mizutani's father used to be a pro-boxer, and she herself infatuated with the sport, he reluctantly joins a boxing gym in order to impress Mizutani.

This is one of the best manga Adachi sensei's ever done. A little ecchi, or should i say fan-service biggrin. Good story, nice romance, but it seems to lack romance sad. As expected, Adachi will give us an open ending. That's quite disappointed me, i want more romance and epilogue, but somehow it's Adachi's style, cant help it.

This one reads like all Adachi mangas I have read so far easy on the eye with a wonderful flow to the story that I enjoy so much . As a plot its not very complex but that is never the point with Adachi san he is the master of light stories and this one is as gripping as Cross Game which I feel, is his best work .

The plot development is like any other of his sport manga. There isn't much things to say about this manga because the basic plot is like any of his other works. I ending didn't surprise me because most of his works ends with an open ending where you just know that the couple with get together. I just thought that there should be at least a kiss or something .

Overall its a good manga from Adachi. It's not his best work but it's still good.

"Cross Game" of Boxing

As others said this is typical Adachi. Embrace and be honest to your feelings; never let go of your dreams. I liked it though, as far as Adachi's works go, surely one of my favorites. Recommended if you like his work and or like boxing manga.

Pretty typical Adachi work *spoiler alert*

What is typical? There is a principle love interest, and several supporting characters "love" that character and tries everything to make that person their own. The principle characters never openly reject those that form the love triangle or polygon.

As expected of Adachi the ending is left open. It's pretty much assumed that the principle couples hook up. I really wanted to see an actual kiss instead of a silhouette, but that's just me.

I enjoyed everything right up towards the end. It felt like it was being rushed, and in doing so, it made the story drag.

This series was really funny at most times.The art was also really good.It's just that it wasn't a manga you just can't put away.I could easily pause for some months before reading another chapter.So I guess there hardly was any suspense.The boxing theme of this manga was often a bit hard to follow,for example during fights.

This was a very enjoyable manga. It had comedy, romance, and drama. It also didn't burden us with too much sports data like other sports mangas that I've read. I would really hope that this gets licensed here in the states, I would love to own the hard copy volumes.

Adachi does it again...

With Katsu!, Adachi does what he does best again...great story telling. This isn't a "boxing" manga like Hajime Ippo per se, but it's a Adachi manga. This means it's a great comedy/romance story that is seemingly cliche yet with just enough twists to keep it interesting. I admit Adachi's specialty is baseball manga, but this is still worth a read if you like his style.

This story is soft, every problems was just solved easily. It doesn't mean that it's bad but it's lack of emotional, twist moment. Besides, boxing part doesn't met my expectation, it seems like Adachi is only really good at baseball story.
Anyway, the plot is still interesting and you can enjoy the unique storyteller.

The problem is that aside from the little bit of romance, it has a lot of fluff. Usually people think of fluff as side stories but there's another side to it. The way the story is written, is way too slow. Almost nothing happens, yet it introduces more possibilities. It develops way too slowly.

I'll have to lower my score. It starts to get ridiculous for no reason. Especially since no one want to even bother to develop a way to win against geniuses. Which is, of course, crap. There would sooner be a physical limit. Also since the romance barely happens, and the guy puts almost no effort into it. we have to assume she'll end up just liking him because he's just good at boxing.

Let's not forget that people seem to stop their lives just cause of him. This kinda thing worked in initial D but completely blew up in prince of tennis. And I don't think it works well here. It happens more gradually here but its still not that interesting.

My final addition: The writing is funny at times. I wanted to like this. But it is in a way, a bad story. With the character's aloof personality, it makes it seem like he's barely struggled at the end. The retcon of a love story, I don't buy it, neither do I buy the eye thing either. I was actually going to check out more of Adachi's works but this might have turned me off to him completely.
