Yozora floats stars in the night sky every day. One day, when Yozora was floating a star in the night sky as usual, a unicorn passed in front of Yozora. Yozora was moved by the elegance and confident appearance of the unicorn, and fell in love with the unicorn. And she decided to attach a unicorn-like vertically and tail to herself. Yozora is very satisfied with her own appearance. Full of confidence and pride than ever, Yozora also floats stars in the night sky as usual.
