Yorito is a high school student who’s obsessed with taking pictures of the sky. A chance meeting at a vending machine introduces him to a girl named Matsuri. Matsuri’s no ordinary girl, though — she’s actually a Yaka, a 350-year-old creature also known the “Calamity of the Night.” Yaka are supernatural beings with strange powers, beings who never age and who possess almost superhuman strength. Because sunlight is deadly to Yaka, Matsuri has been forced to live a life of solitude, and Yorito is the first friend she’s ever had. There’s even more to Matsuri, however, than her big secret. She’s being followed by Takeshi, a mysterious sword-wielding man who’s intent on killing her. But why? And why is Takeshi unharmed by Matsuri’s powers? Thrust against his will into an otherworldly battle, will Yorito find the courage to protect Matsuri, their friendship, and himself? - from Amzon
