Midori is the story's central heroine and Reiji's childhood friend—the one fans generally agree has the strongest feelings for him. Their connection runs deeper than his relationships with the other girls in the series.
She's on the shyer side, which makes her jealousy toward the other girls and Reiji's growing harem pretty obvious. That insecurity sometimes causes her to push him away out of frustration, though it's really just a sign of how much she actually cares about him. It's the classic tsundere dynamic, except her coldness comes from genuine emotional conflict rather than just playing hard to get.
