Cinderella was never this dashing!

Otogi Grimm, a far-flung descendant of the renowned Grimm Brothers, has always regarded the fairy tales his ancestors concocted as pure fiction. Unfortunately for the introverted half-Japanese teen, he is about to discover that the Grimm legacy is anything but pure.

Upon receiving a posthumous letter from the dead father he never knew, Otogi transfers to a new school and moves into an abandoned mansion as part of his inheritance. There, he finds a manuscript that reveals the truth about his ancestors: the Brothers Grimm made a deal with mystical beings known as the Märchen Demons, who now have a claim on Otogi's life. With a dashing male Cinderella as his guide, can Otogi Grimm unlock the power of the manuscript and stop the fairy tale demons before they destroy him first?
