He was always protective of her, but this time it was gonna be hard to pull it off.
She had become the unwitting host to a gang of scraggly demons, they had followed her from her last life and had layed claim to her. Her destiny was to be a suicide.
The only way he was gonna be able to stop them was to sacrifice himself for her. After all, he had dealt their kind before and he was awake enough that their subconscious attacks would not phase him much. So a transference attempt was necessary. The only way to do this was to degrade himself to the point that the demons would consider him a more delicious subject. So it began and one by one, they left her for their new home in him.
She is now free and happy. He killed himself 2 years ago.
