The sands of time do not stop for anyone... but for Kiyoi they seem to have stilled. Or, more correctly put, the sands resting at the bottom of life's hourglass have vanished, leaving behind only a few grains to proof their existance.
Without a Past, there cannot be a Present, and without a Present, there cannot be a Future.
Kiyoi is locked up in her own doubt and pain. Emprisioned by the feelings of gratitude and helplessness. But as Fate is already traced and unavoidable, nothing can stop the hourglass from being flipped over.
