Sisters Hana and Yuki Shiraka have reached their fifteenth birthday, and their proud widowed mother teaches them how to summon their fairy godmother. However, their old godmother, Miss Sacharissa, has retired and been replaced by Miss Florence, a young and very unbusinesslike woman.
Hana asks Miss Florence how to become a hero. Heroes are always male, giving
Florence the misimpression that Hana wants to be a man. However, once she gets the idea that Hana wants to become the first FEMALE hero, she decides to take time off to take her to the capitol city, Legend. Yuki wants to come as well, and they leave, despite their mother’s rather bemused protests.
