Reborn: Card Collecting Pitcher

[Lol, I tried writing a stern novel-like synopsis, comment if you like it :) ]



Itsuki Ayaka was once hailed as a rising genius in the world of baseball. But he wasn't a natural prodigy — his success came from relentless hard work and sacrifice. At just 18, full of passion and competitive fire, he pushed himself beyond his limits, bending to the whims of a manipulative and abusive manager.



"Arghhhh...!"



But eventually, his body and spirit broke. Itsuki failed, his glory faded, and he found himself clinging to the remnants of a once-promising career, a fallen genius lost to time.



Until one day... everything changed.



“Damn, it seems like I’ve regressed…!"



Now back in his younger body, with all the knowledge of his past mistakes, Itsuki finds himself armed with an unexpected gift — a mysterious system. Can he rewrite his destiny and reclaim his future, or will the shadows of his past haunt him once again?
