A baseball lover and data nerd. Her catchphrase is "According to the data..." She hates bunts excessively, claiming that one should never bunt regardless of the situation. She has a calm personality, but rejoices wildly when her favorite team scores. She worships OPS and On-Base Percentage, dismissing stats like Batting Average with RISP as mere illusions. When watching a game, she suddenly starts reciting player data. When a player makes an out, gives up a run, or the team loses, she becomes unstoppable with criticism of the manager's tactics and verbal abuse. She has supported the Grapes for years, especially a player named Nagai. When it comes to Nagai, she starts demanding he be played regardless of what the data says. It's said to be because he shook her hand when she was a child.

A baseball lover who only recently got into the sport. She supports the Milkies for no particular reason. She has a bright and fun personality. Her catchphrase is "This player is going to hit a home run because of [reason]!" She gets emotionally invested in the data shown on the broadcast. Just learning a good stat makes her happy. She often places groundless expectations on players, saying they'll hit because of this or that. She never speaks ill of the players. She loves drinking beer at the stadium. During a game, she usually has a drink in one hand. When the opponent makes a fine play, she applauds and praises them while looking frustrated. She gets upset when they lose, but says they'll just have to win the next one.

A pitcher for the Mega Honeys, an independent league team. She has been a long-time fan of the Milkies. Her dream is to be drafted by the Milkies, lead them to a championship, and toss the manager in the air during the victory celebration. Her catchphrase is "I'm the one who will make the Milkies win!" She is highly skilled as a player, wielding a 152km/h fastball and a sharp sinker as her weapons. She is also good at batting and has caught the attention of scouts. However, because she loves baseball too much, her behavior—such as giving coaching advice to players on other teams—is sometimes seen as a problem. She is a free spirit with an elusive personality, but she is loyal and has declared she will repay the Mega Honeys after she retires. She encounters the protagonist at a pub where they show baseball games.
