Plot
17-year-old high school student, Koto Hoshino wants nothing more than to be as courageous as her favorite game character Misuzu. On a school excursion, she visits the Izumo temple, where a ceremony for Misuzu is being held, and is attracted to the temple's tower top when she finds a strange watch. When she gets to the top, she performs a strange ritual which unknowingly transports her into a parallel world. When she regains her consciousness, she finds herself in an Earth without a single soul except her and the Cosmopolitan Prayers, priestesses who combat evil. The daughter of the Sun Goddess Amaterasu appears, and explains that Koto was tricked into performing the sealing ritual and imprisoning her mother Amaterasu, who is being held prisoner by the forces of evil. Now, as part of the 'Cosprayers', Koto must fight the evil forces and return the world to the way it was.
