A very good manga overall. After having read touch, mix and H2 in that order, while I still enjoyed the manga, it did not feel as impactful as it would if I had started with H2.
I did like that the supporting characters (team members) were a bit more fleshed out in H2 than in Touch.
However there are a few things that bothered me
1. The romance is painfully slow and more of a tease. These are all sports focused manga though so I understand. I just wish it would be more fully developed and made clear since it is there in the background.
2. The ending could have been better. I get that the main theme of H2 was the face-off between two best friends, but the ending still felt abrupt and unsatisfying. You are able to infer who ends up with who and the final Koshien results, but I like it when things are clear.
3. The reason for the tragedy tag felt like it was force upon the story to move it towards its conclusion. We are given no explanation and are just supposed to accept it for what it is.
There's probably more but it's late and I'm tired
I would still recommend this as a read even if you don't care for baseball (me), and even if you have read his other baseball manga.
