The Poison Maiden

Hana, a 23rd century assassin dies at the hand of her master. A man she had desperately wanted to please throughout her life. Instead of feeling the cold hand of death, she wakes in the body of a 17 year old blind girl, with the same name as her. Thrown into a world where Spirit Power is the essence of ones worth, she quickly realizes her new body is quite special as she has the ability to heal. Unfortunately, this is a skill not very useful for someone used to taking lives for a living.
With the determination to keep her new body alive, she finds herself in a world where the weak are easily killed and only the strong can stay alive.
