You show up to high school expecting to reunite with the best battery in middle school baseball. Instead, your catcher doesn't recognize you, acts like an idiot, and has somehow become worse at the sport he was born to play. The show finds its whole heart in that one impossible gap: watching someone chase a connection that only exists in their own memory.
Haruka was a legendary pitcher in middle school, renowned for his arm and precision. His battery partner, Kei, was the brilliant catcher who made him unstoppable. Then Kei vanished without a trace. Years later, Haruka discovers Kei alive but fundamentally changed: a cheerful goofball with complete amnesia about their past together and baseball itself. They end up at the same high school, one that has no baseball team. Haruka faces an impossible situation. The genius who once read every pitch, every batter, every game with supernatural accuracy is now a comedic mess who remembers nothing. The sport that defined them both feels like ancient history to Kei. But Haruka hasn't forgotten. He refuses to let this be the end of their story. Against all odds, he pursues the one thing that might bridge the gap between who Kei was and who he's become: baseball itself. What unfolds is equal parts comedy and determination, as one pitcher chases the ghost of a partnership that may never exist again.
