Yoshika Miyafuji is first seen rescuing a cat from a tree, which her friend Michiko Yamakawa admires her for doing so. Later during the day, while Yoshika hitches a ride with Michiko's grandfather, a dog suddenly appears and crashes the wagon, and Michiko ends up injured. Once it is shown that Yoshika has magic healing abilities, she is approached by Mio Sakamoto to become a member of the special aerial infantry that is fighting against the mysterious Neuroi. Yoshika initially refuses her offer, until she receives a letter that supposedly came from her dead father, Ichiro Miyafuji. Yoshika accompanies Mio on the aircraft carrier Akagi, which soon comes under a surprise attack by the Neuroi.
