Tsubasa Kurenai is a guy who is in love with Ukyo.  He also has the habit of crossdressing.  His "Habit" is not very typical so he fools both Ranma and Akane.  He met Ukyo when she was attending the all boys school. Finaly Ukyo told Tsubada that she was engaged to Ranma. He then hunts down Ranma and attacks him repetedly.  Eventually he is found to be a guy and runs off.
