Mizuho Amane

Mizuho Amane is Shiratori's classmate who uses her batting skills to punish Tsubasa for his womanizing. She normally uses a spiked baseball bat, but "because of the adults' circumstances", her bat was taken away and replaced with a plastic megaphone. In the epilogue of the manga, she is shown to have become an editor, despite studying to be an author (this is possibly because of her lack of drawing talent).
