The captain of the Powerful Alliance. He loves baseball more than anyone and can handle any position (except pitcher) with ease. He is well-liked by everyone as a genuinely good guy.

Pawapuro's best friend. He is fast on his feet but chokes under pressure. He ends his sentences with "yansu" and has a huge weakness for beautiful women.

The ace pitcher of the Powerful Alliance and Pawapuro's classmate. He is handsome, has a great personality, and possesses outstanding athletic nerves, but he can also be stubborn and hates to lose. He masters the breaking ball known as the "Star Drive."

Pawapuro's eternal rival. A genius left-handed pitcher with breaking balls like the high-hopping "Rising Shot," the high-power "Rising Cannon," and the further evolved "Kaiser Rising." He is also an extraordinary batter. While he has a haughty personality, he is a good guy at heart.

A pitcher from Teio Jitsugyo High School. He values hard work and hates being called a genius. Despite his flashy appearance, he is a hard worker who supports his family's finances with part-time jobs.

An underhand pitcher with skills that rival the boys. She practices daily while serving as a manager, aiming to play in official games. Her weapon is the breaking ball "Marine Ball."

A southpaw from St. Tachibana Academy with a finishing pitch called "Crescent Moon." Her tomboyish, competitive, and slightly stubborn personality gives her a bit of a devilish charm. She loves pudding.

Mamoru Ikari's younger brother and a super high school-level catcher with a strong arm and skillful hitting. Unlike his confident and haughty older brother, he has a mild personality and is kind to both people and animals. The adhesive bandage on his cheek is his trademark.

The coach of the Powerful Alliance.

The managers of the Powerful Alliance. Haruyo Motowaka: Pawapuro's childhood friend and a martial arts master. Mio Akizuki: A tsundere manager.
