Kozue Nanao is Godai's kind-hearted girlfriend. Its difficult to call her his girlfriend actually as the relationship is very complicated.
Kozue is hopelessly devoted to Godai, but he's in love with Kyoko. He began dating Kozue soon after Kyoko moved in, and has always planned on breaking up with her, but has never found the right time. And even though he does want to end things with her, Godai really likes Kozue. The reason he doesn't end thing with her early on is because of the fact that he cares so much for her.
Kozue is very different from Godai's other love interest. She's very sweet, and always puts Godai first. She makes no effort to hide the fact that she is in love with Yusaku and would be happy to marry him whenever he's ready.
Kozue never forgets a holiday and showers Godai with gifts throughout the series. She takes care of him when he's in the hospital and spends time with his grandmother. She is a picture perfect woman who has no idea that Godai is secretly in love with Kyoko.
The Meaning Behind the Name
Kozue has an interesting name meaning. It translates to "small stream" which reminds me a lot of her personality. Nanao means "seven tails".
