I got this smack dab in the middle of the series, and am really only familiar with the OVA of the same title. However, I will try to give you a review of what I have read!

The story is basically about a girl whose family owns a judo dojo. She herself is training, and is incredibly strong (although she doesn't really recognize her own skill). Her story revolves around her affections for judo, and two boys. I really don't like Kitagawa's style of artwork -- it's too cute, and perhaps better suited for a slightly etchi style. Also, I find the concept of the story to be rather mundane; there's really not much to pick it out from other series.
