Aira, a 16-year-old witch trainee, is in a relationship with Shinjo, who reveals he has no memory of his childhood. Aira uses her family’s time-doors to investigate his past and discovers he was once her childhood friend named Kairi. Returning to the present, she finds Shinjo has changed back into Kairi, who no longer remembers being Shinjo but retains memories of his time with Aira. As an evil comet threatens Earth, Aira must decide whether to mourn the loss of her boyfriend or work with Kairi to prevent disaster. The story includes four special epilogue chapters.
