Kira (The Return of Mohanna )

"Leave. All of you. Leave Elezalde. Go and increase your kind. But take heed, from tonight don't let yourself get bitten by a Shade. Because tonight, every single human that has murdered his fellow human will become a Shade and just a single bite from a Shade in it's beast form is lethal to a normal vampire", she said. Then she turned to face the shades.
"Speaking of which"
Baal stepped forward.
"Oh Baal. I would've liked for you to join your new species to fight me but..."
Kira vamped to stand behind him, put one of her hands at the back of his neck and the other hand on his chin and she snapped his neck. He fell unconscious.
"...our fight is gonna be one on one"

Kira wished for a normal human life. But apparently that wasn't gonna workout for her. She was already a Guardian and according to the myths and legends, she was destined to manifest as the incarnate of the Ancient and Powerful Demon-Witch Hybrid Mohanna but more powerful, as she was a Guardian thereby making her the Tribrid.
