Tezuka Haru has been desperately hunting for a job, but nothing seems to come about. Without thinking about the consequences, she takes and barely passes the necessary exam to enter the world of aviation. From then on, she begins to walk the path towards becoming a female pilot. Of course she struggles a lot, especially since the training is more severe than she expected before taking the exam. She bonds with her fellow cadets, has to deal with some very strict teachers, and meets various people while going through the pilot training.
