Nagisa: looks relatively diligent, actually doesn't know shit about baseball, but at least rather attentive
Ichinose: looks like she'd wreck the team with love tangles, actually is a pretty pure maiden and the most dedicated to baseball
Himemiya: looks like an innocent goofball just hanging around for the lulz, actually is pretty sadistic and wrecks the team with love tangles (for the lulz, apparently).
