And in this organization is a member named Shitou Soratarou. As a member of Fairy Agency, Soratarou works to protect people. However, Shitou Soratarou is just an alter ego of Gertrud.

One day, Yumeka found out that an extraordinary and powerful blessing resides within her. Using the power of this blessing, Yumeka transformed herself and decided to use her power to fight for people's happiness and peace as "Fairy Bullet" Meanwhile, Soratarou who has witnessed Fairy Bullet's power began to make his move in order to acquire her power so that he could secure his position as the successor to Kaiten council.
