Demon Heart

Naoko Kitamura is one of the best cops in the city's police force in Osaka, Japan. However, her human appearance hides a dark secret that must be hidden from humans. Naoko is a demon hybrid, a descendant of a demon and a samurai.

Struggling to uphold her mother's legacy as defender of Japan against evil, she faces human and nonhuman enemies determined to alter her country's destiny. Her powers are both a blessing and a curse, for, by being extraordinary, Naoko can never live an ordinary life.

For her, the road to victory will be written in blood.
