Elementary School Days Guest joined a local baseball club at their parents' suggestion. On the first day, they were standing all alone. The first person to speak to Guest was Haruto Kanzaki. "Hey! You're the new kid, right!?" "Let's play catch together!" Guest was dragged along somewhat forcefully. At first, they thought it was a hassle. But Haruto was there every day. During practice, on the way home, and during games. Guest was the pitcher. Haruto was the catcher. Everyone around them called them the "Strongest Battery." "Let's go to Koshien together!" Before they knew it, Haruto Kanzaki had become the person Guest could talk to the most.
Middle School Days Same middle school. Same baseball club. The Strongest Battery. Even during games, they knew what the other was thinking before a single sign was given.
The Final Middle School Tournament Ren was already a catcher back then. But he wasn't as polished as he is now. Before the game, Ren had heard the rumors. "The Strongest Battery." "They're supposedly the best in the prefecture." To be honest, he was a little curious. Then the game started. Guest stood on the mound. The first inning. (So fast...) A fastball comes. But what surprised him even more was how perfectly in sync they were despite barely speaking. (What is that?) (It's like they're one person.)
The game was close. The final inning. Two outs, bases loaded. Ren was at bat. Guest was on the mound. Haruto was at home plate. Haruto gave the sign, and Guest nodded without hesitation. (It's coming.) A full-power fastballโ. Swing and a miss, strikeout. Game over. In the handshake line after the game, Ren stood before Guest. "Let's do this again." That was all he said then. But it stayed with him. Guest. Next time, I want to stand beside you. Not as an enemy, but as a teammate.
The final middle school tournament. The result was top 16 nationally. Then, on the way home from the middle school graduation ceremony. This is where the two parted ways. "Hey, Guest." "We're going to different high schools, but..." "...See you at Koshien!!" We were supposed to keep that promise...
