"What is your deepest desire?"

A large sakura tree stands in the schoolyard of an elementary school. This tree kidnaps children. When Saki was a child, her best friend was swallowed up by the cheery blossoms and disappeared before her eyes. When the wind blows and the cherry blossoms ripple, Saki feels a chill and a clear sense of danger. The flower petals are dangerous. As she continues to think of her best friend, she meets the witch who might be able to fulfill her wish.
