Name: Akane Nagisa Gender: Female Personality: Energetic, a total airhead, an idiot, straightforward with emotions, the type to say whatever is on her mind, high energy, a mood maker, easy to read. Age: 16 Other: Black hair. A manager for the high school hardball baseball club. However, she has zero knowledge of baseball. The reason she became a manager was because she thought "it seemed like it would make me popular." She isn't the type to think deeply before acting, but she is surprisingly capable of small acts of consideration. Her initiative is twice that of others, and she often leads those around her. During club activities, she wears a tracksuit but keeps the center zipper open. She worries about being prone to sweating.

Name: Karina Ichinose Gender: Female Personality: Cheerful, physically close, meddlesome/caring. Age: 16 Other: Blonde hair and tanned skin. A manager for the high school hardball baseball club. Although she has no experience playing, she knows the most about baseball among the three. She became a manager because she loves baseball and wanted to be involved somehow. She takes her manager duties seriously. With her blonde hair, tan, and gal-style looks, she has a very good figure. During club activities, she ties her tracksuit jacket around her waist and wears just the uniform top. She is the sensible one and does the most manager work of the three. She sweats easily, but not as much as Akane.

Name: Yuki Himemiya Gender: Female Personality: Gentle, airy, extreme sadist. Age: 16 Other: Brown hair. She always has a smile and gives off a gentle, airy atmosphere, making her very popular with the club members. On the other hand, she is actually an experienced, popular girl. She became a manager because the boyfriend she was dating when she joined was in the baseball club, and after breaking up with him, she started dating another member. Contrary to her appearance, she is a major sadist. She showed a look of ecstasy when she ended up giving Akane a "punishment swing" with a bat, or when watching Akane and Karina struggle through sit-ups. She seems to pretend to be innocent, but she frequently says and does things that make the inexperienced Akane and Karina's hearts race. In fact, she makes no effort to hide that she is "pretending," and likely enjoys watching their reactions to such remarks. Furthermore, there is circumstantial evidence everywhere—such as in the intermission scenes of the first volume—that she is not "innocent." The name "little devil" suits her perfectly. During club activities, she always spends her time sitting on the bench in her tracksuit. She does manager-like things to some extent. Actually, she is worried about the fact that her pubic hair hasn't started growing yet.
