Akaza Yukiko (Sugisaki Hana) has suffered from eye disease since childhood. Although she is not completely blind, she can only feel weak light and color. Therefore, Yukiko attends a school for the blind. For Yukiko, the most important partner in life is the white cane in her hand. It is her hand and eyes, which can protect her from harm. Although her life is full of misfortunes, Yukiko grew up in the meticulous care of her relatives, so she is very optimistic and cheerful, and full of expectations for the future. By chance, Yukiko offended a gangster named Kurokawa Mori (Sugino Haruko) on the street, and inadvertently used a "fatal chicken" on him. Who knew that this kick not only did not annoy Mori, but awakened a different feeling in Mori's heart. Mori was deeply moved by this kind and strong girl and decided to play the role of her protector.
