I'll be interested to see what route they take to make this different to the existing similar baseball manga. So far to me this has felt very similar to Major, and I can see it falling in with the same tropes as we've seen a lot before "There's no time to learn and master a breaking ball before X tournament", so we end up with yet another baseball manga protagonist who can only throw fastballs. It's "exciting", I suppose, but when it's been done to death already it doesn't leave a lot of room for interesting and unexpected character growth.
