At first, I thought this was going to be Adachi's weakest large baseball manga work. How can you top Cross game, not even touch did. Plus it didn't have a huge hook like the the others. Well I'm basically just setting it up to say I was wrong.
Without a hook this ends up being a story of four people, all equally good. The title is explained as two heroes, though it also has two heroines. Though one girl is more of a heroine after awhile, and even a side girl gets more pages and story. Overall it's like a more subtle(mature because the author has matured) version of Touch, that doesn't rely on death.
I really can't overstate how that impacts what a good read it is, the fact that both guys are there from the beginning, and both are people you can like. The girls at first are also equal but one seemingly doesn't get as much written about.
Still, I don't really like the ending. It seemed like it was going in an interesting, unexpected direction but then it just ends up where we already were the entire time. The main character never really fights for one of the girls. How is a baseball game going to resolve anything. It doesn't change the fact that she does have growing feelings. I didn't mind at first, but it grows and grows as the story goes on, so it gets irritating.
Another thing about the ending is that it's classic Adachi, he doesn't save time for it or bother with it. So after spending volumes on baseball, he can't spend anything more than a couple of panels with the characters talking about where they are and going with the aftermath. Not since his early, less than ten volumes works, have things been left so unresolved(think Hiatari Ryoukou).
