She's reckless; He's cautious.
She's synthetic; He's all-natural.
She's tricky; He's disciplined.
A negative and positive relationship combined with an on and off chemistry.
They're two mismatched pieces.
They formed a perfect battery.
Aira Yoshida, one of the best pitchers in the world and also the reigning queen in baseball, suffers an injury which caused her to stop playing baseball for a short period of time.
Hearing Seido's loss and learning about her father's invitation gave her the reason to go back to Japan. And now that she's back in her native country--she found a new battery mate.
And that person is the one and only Kazuya Miyuki.
Join them in their quirky adventure as they explore this roller coaster ride of life!
