Onikirisama no HakoirimusumeOnikirisama wa Hakoiri Musume

A boy opens a chest at his father's temple, and inside pops out a Hanyou, a half demon, half human girl who wishes for nothing more than to avenge the death of her mother, and her father by herself. It just so happens to be that the boy looks just like his ancestor, the one who killed the girl and mother.
