A player for the Place Name League team "Okayama Nishi-Nihon Sea Wells." Position: First Baseman. The 2025 first-round draft pick for Okayama, known for confounding opponents with fast feet and heavy hitting. During high school, she appeared at Koshien for three consecutive years, proving her talent with a career total of 32 home runs and 94 RBIs. Her cute fashion sense is also part of her charm. 18-year-old female, from Hofu City, Yamaguchi Prefecture.

A player for the Place Name League team "Tohoku Miyagi Starters." Position: Catcher. A standout talent who entered the league through a tryout and became Tohoku's third-round pick, showing great promise in hitting. A mysterious and eccentric girl. While she has a human appearance and a mouth, she cannot speak; she expresses herself by nodding, shaking, or tilting her head. She shows emotion through her eyes—looking downcast when sad or sparkling when happy. She is ignorant of many things. She is a human-like being born from a mutated jellyfish. She wears something resembling a jellyfish hat. Gender, age, and birthplace are unknown (though she claims to be an 18-year-old female from Tsuruoka City, Yamagata Prefecture).

A player for the Place Name League team "Hokushinetsu Liners." Position: Outfielder. The 2025 first-round draft pick for Hokushinetsu, possessing high physical ability. A true genius who won a national championship in Kendo during middle school, then started baseball in high school, serving as captain and the number four hitter while leading her school to its first-ever Koshien semi-finals. She excelled with both the bamboo sword and the bat. She occasionally practices her swing with a bat as if it were a bamboo sword (she is completely serious about this). She has a serious demeanor but is soft-spoken and knows how to let loose when the occasion calls for it. 18-year-old female, from Komatsu City, Ishikawa Prefecture.

A pitcher for the Place Name League team "Tokyo Yamanote Loops." The 2025 first-round draft pick for Yamanote, who confuses opponents with a variety of breaking balls. She is uniquely active as both a baseball player and a model. She has a passive personality and finds it hard to say no, which led her to start modeling in high school because she couldn't turn down a friend's invitation. Consequently, many people recognize her face, and since trouble often follows, she usually has someone accompany her when she goes out. Perhaps because she feels safe in private spaces like one-on-one settings or private rooms, she is surprisingly clingy. She is close friends with her teammate Yumi Oimachi, and the two are often seen together. The red glasses she usually wears are a hand-me-down from Yumi. 18-year-old female, from Yotsuya, Shinjuku-ku, Tokyo.

A pitcher for the Place Name League team "Tokyo Yamanote Loops." The 2025 second-round draft pick for Yamanote, possessing strong mental fortitude and suppressing opponents with balls that have a sharp drop. Her real name is Yumi Oi. She is very generous with fan service, winking at fans, readily agreeing to photos, and striking up conversations with total strangers. While she has a very bright personality and is physically affectionate with friends, she is close enough to Aika Yotsuya to call herself Aika's "bodyguard" and is constantly worried about her. 18-year-old female, from Oi, Shinagawa-ku, Tokyo.
