STORY

An unassuming and much-abused (?) castle servant encounters a mysterious demon... and is transformed into a half-demon himself!

Though baffled at first, Shiro soon begins to accept his newfound life. Although free from the various torments of court, Shiro now finds himself in the center of chaos and trouble...

What are the mysterious demon's true intentions—and what will become of our liberated hero?!
