28 years old. A pitcher for the local pro team, the Hiroshima Slyles. He is Maki's former classmate. Recently, egged on by another former manager, he pushed Maki down a flight of stairs at a park, causing her to lose her memory. Following the incident, he proposed a three-game showdown to ensure she ends up with him, imposing a condition that she cannot recruit pro players to make it easier to win her over. First person: I (Ore, arrogant).

29 years old. An infielder for the Slyles. He became close with Maki after she joined the team. Since the incident where she was pushed, he has been asking his teammates Kikuchi and Maru if she hates him, but they told him he needs to ask her directly. First person: I (Ore, casual).

24 years old. An outfielder for the Slyles. He looked up to Maki because they worked together like two halves of a whole on his batting coaching. Since the incident, he finds it hard to talk to her. Seeing Hori, a glove maker he knows, talking intimately with Maki makes him jealous. He secretly wishes for Maki to stay with him forever. First person: I (Boku, polite/soft).

28 years old. A glove craftsman who services the local team, the Slyles. He talks frequently with Seiya Suzuki. He serves as the pitcher for the first game of Maki's showdown. He senses that Seiya is jealous of him and is excited to be teamed up with his former partner, Atoda. First person: I (Ore, casual).

28 years old. The starting catcher for the corporate league team, the Eliols. He calls his former classmate Nomura by his first name but is disappointed that Nomura doesn't remember him, though he figures that's why Nomura messed up twice. He is thrilled to team up with Hori and scores the first points of the game with a home run. First person: I (Ore, blunt).

28 years old. The starting catcher for the corporate league team, the Marlins. For the second game, Maki asks him to bring his whole team to her side, and he agrees. Using his two ace pitchers—the lefty Shinoda and the righty Masaki—he overwhelms the Slyles' hitters. Nomura remembers his name, but Taira only remembers his classmates Atoda, Hori, Nakata, Maki, and Itsuki, as well as Kobayashi who made it to the pros. First person: I (Watashi, formal).

28 years old. The ace pitcher for the corporate league team, Elias. He is Maki's relative. His juniors, Kato and Tamai (who are now with the pro team Fighters), treat him with great respect. For the third game, Maki asks him to bring the Elias team to her side, and he agrees. When Nomura shouts "Kuroda!" at him, he assumes Nomura is talking to Maki, so he introduces himself to Suzuki and Tanaka. First person: I (Watashi, polite).

24 years old. An outfielder for the Central League Swallows. Since his father and Maki's father are close friends, he calls Maki "Maki-nee." Having trained his batting theory with Maki since childhood, he is already a star slugger in the pros. He is unaware that Seiya Suzuki is jealous of his close relationship with her. First person: I (Boku, soft).

28 years old. A catcher for the Central League Giants. He was classmates with Maki, Nomura, Itsuki, Atoda, Ito, and Susumu Nakata at Konan High School and remembers them well. In high school, he and Nomura lost the Koshien finals after giving up a home run to Isoda, which led him to rethink his catching theory. He is one of the few people who can give Nomura blunt advice. First person: I (Ore, calm).

33 years old. His younger brothers are Yuji (30) and Yuzo (28) of the Hawks. He is famous among high school baseball fans as the man who led an obscure public high school to a Koshien championship. He is a pitcher. His catcher back then was Tsubasa Aizawa (33), now with the Marines, and his opponent in the finals was Yoshiyuki Kamei (33), now an outfielder for the Giants. Along with Kanda, the owner of the coffee shop Roman-tei, he toyed with Kosuke Tanaka. First person: I (Ore, mature).
