To Dispose of Roses

"You're so much like your father."
I didn't know what to say about that. She rarely ever brought him up.
"I wouldn't know, I've never met him."
"You wouldn't want to."

Hiroto is misguided. He is irresponsible, aggressive, and always getting into fights with gangs and not to mention getting beaten up.
He has no aspirations in his life and spends his days messing around with his rebellious friends.
It isn't until French exchange student Fleurette comes to stay with one of his friends that everything in Hiroto's life starts to change.

Their problem; she is an innocent human and temporary member of a gang-like group of friends who are reckless blood-thirsty vampires.

This book runs parallel with 'A Drop of Purple' by @Werecat in which eventually the two books will join together.
