Summary
After leading Seidou to back-to-back Koshien championships as their undisputed Ace, Sawamura Eijun had finally conquered it all. He had survived the Yips, outlasted his rival Furuya, and proved that a loud-mouthed kid from the countryside could rule the mound. He was content, decorated, and ready for the future.
Then, he woke up.
Instead of his hard-earned gold medal and professional-grade muscles, Sawamura wakes up in his scrawny, 14-year-old body back in Nagano. He is a second-year at Akagi Junior High—a time when his pitches were unrefined and his "Numbers" didn't even exist. In a single night, the universe robbed him of his glory, his teammates, and his hard-won progress.
Furious and cursing the "Bastard Gods of Baseball" at the top of his lungs, Sawamura realizes he has two choices: mourn the future he lost, or use his "National Champion" brain to absolutely demolish the past. Armed with veteran instincts and surgical precision, the "New" Sawamura is about to turn the middle school baseball world upside down—and this time, he isn't letting anyone else take his mound.

Summary
The final game had ended days ago.
The cheers were gone. The trophy sat forgotten on a shelf in the classroom. His teammates were still buzzing talking about scholarships, uniforms, and the pros.
Sawamura Eijun... walked home in silence.
The sun had dipped behind the trees by the time he reached the hill. From there, he could see the empty field they’d played on as kids. The old diamond still faintly visible.
A breeze rolled over the dirt, lifting dust into the fading light.
He stayed there for a while.
Just watching.
---
“Are you going to keep playing?”
His mother’s voice from that morning. Soft. Careful.
“I guess,” Eijun had said, eyes on the floor. “I mean... I don’t hate it.”
She hadn’t asked more.
That night, lying in bed with his glove on the windowsill, Eijun stared at the ceiling.
Everyone kept talking about high school. About Koshien. About scouts.
But when he closed his eyes, all he saw was dirt, a spinning ball, the sound of the mitt.
That was it.
No crowd. No spotlight.
Just that moment.
And for now, it was enough.
