Nobody had written a review yet so I decided to write one.
This is also my first review ever so if something is lacking or totally biased please understand.
The story tells the continuation of Diamond no Ace. I recommend reading it first or finish both seasons of the anime.
The story in Act II is not that different than in Act I, except for new grades and new characters. For me, the storytelling is stable and no sudden drop in hype.
For the art, from the first time I read it until now, it's amazing. The readers can feel the intensity, the characters' feeling, and others just through
the art alone. Of course the baseball action is brilliantly done.
The characters are really well made and well developed, but some characters have only little development. The addition of new characters may overlap those characters' development, but it's still very fun to read. Considering that Sawammura is no longer just a junior, the manga is really focused on more Sawamura development than other characters like the first years.
I personally enjoy every dialogue, every frame, every page, and everything of Diamond no Ace especially in Act II. The comedic scenes also haven't dropped a bit. Every new updated chapter feels very short and I can't wait for the next one to come out.
Overall, it's a brilliant manga and is really greatly taken care of. All characters are lovable and fun to read. I really really really recommend this manga.
