A supernatural fantasy from the best-selling creator of Full Moon and The Gentlemen's Alliance †!

Sakura is the granddaughter of a mysterious moon princess who slew demons with her Blood Cherry Blossom sword. All her life Sakura has been forbidden to look at the full moon without knowing why. Then one night, unhappy over her impending marriage, Sakura gazes up at the moon, only to see a demon attacking her...

Sakura, still grieving Oumi’s death, must fight the powerful youko of Uji. But she finds herself no match for the demon’s poisonous vapor. It’s time for Kohaku and Hayate—with a little help from the full moon—to step in.
