Wild Spirit (A Hellsing FanFic)

Valeria Moreau is a genetically modified human. She was kidnapped as a child by scientists who wished to gain more knowledge of their progress on a new type of soldiers that could benefit the Queen of England.

The result was making her able to shapeshift her body into the body parts of certain animals or mythic beings. When Valeria turned fourteen, she managed to escape and became a mercenary.

Ten years later, Valeria is hunting down a vampire that had taken over a hospital in Ireland, when she clashes with not just a certain red vampire, but the priest Anderson as well.
