Mei Ayazuki, an ordinary high school girl, becomes the object of affection for a bunch of handsome historical figures when she accidentally time-travels back to Tokyo during the Meiji Era.
Mei's memories of her time that had been lost have begun to return. She remembers being isolated because she could hear the voices of ghosts and how she would cover her ears to block them out in fear of being hurt further. All the memories come flooding back to Mei and certain emotions begin taking root in her heart. Furthermore, the promised night of the full moon has arrived.
