I love how positive Hyoro always is, how he never gives up and always pulls everyone together to move forward.
It's cool how first it's Shiro's shoulder that they all fight for in the first Drump arc. Then it's Hiroshi who's injured, and they all fight for him. You can see how much Shiro's experience changed him because it's so apparent in the WABC arc just how much he really cares for Hiroshi. I love the relationship between Shiro and Kuro, but I also love the relationship between Shiro and Hiroshi, too. They all respect each other so much as both rivals AND fellow baseball players.
I'm happy that the author let Suzu do something actually, since he didn't do much in the previous book.
That World Ball defies the laws of nature. I don't get why it's so hard for Kuro to hit, though. He admitted it himself in book 10 that Shiro's control is so good that he gets it in the same strike-zone spot every time. So why doesn't he just swing with all he's got in that spot and hit it like he does with his Hissatsu Driver Shot?
It's interesting how Kuro and Drump, though on opposite sides, are both fighting and trying to win the match for the sake of an injured loved one they'd made a promise to. That's what makes them so serious and desperate to win the game and do their best.
The part where Kuro's friendly rivalry with Shiro sparks a fire in him to get through the new obstacle and helps him to defeat Drump's makyuu was satisfying to read. It was a good element to end with.
