Kinoshita Midori

Midori met Kazuhiko and the gang several years before the story began. She was a member of the swimming club and was usually by herself before she met our protagonist.

She was an incredibly good swimmer, but a car accident ended her prospects. The damage to her spine was permanent, and cost her the use of her left leg.

Still, Midori is weighed down by her inability to walk to the point that she feels no one would find her attractive. This has effectively destroyed any hope she had for a relationship. Midori also feels like she is a burden to others, and prefers to do things on her own. While she tries to use her cheerful disposition to hide these feelings, they have not gone unnoticed. Her father in particular has noticed it, and even mentions that Midori's "true" smile seems to come out only when she's around our protagonist.
