In the Imperial Court where the bowstring rings to repel evil, the cry of a monster echoes again tonight...
The story is set in a fictional island nation in the East, modeled after Heian-period Japan. The appearance of the Nue is based on the 'Kanmon Nikki'.
Across the ages, that voice echoes eerily through the capital time and again. A voice resembling a baby's cry or a woman's scream—people began to call its owner the 'Nue'...

At a certain point, this monster began appearing frequently in the Imperial Palace where the Emperor resides. Specifically, in the Eastern Palace where the Prince lives.

The Prince, sickly by nature, became bedridden due to fear and mental exhaustion.
The Emperor, concerned for the Prince, specifically chose Masumi Takamura—the most loyal, courageous, and skilled archer among the Tachihaki-no-Toneri (Imperial Bodyguards)—and ordered him to live with the Prince and serve constantly by his side.

Takamura is a man said to possess eyes that see through demons, a heart that cuts through evil, and the power to strike them down.

As Masumi sounds his protective bowstring by the Prince's side, the Prince finally finds the peace to fall asleep.

However, the Nue monster, captivated by the Prince's beauty, is watching for any opening to snatch the young man away...

While not particularly cruel or cold-blooded, he has an unpredictable nature that humans cannot fathom.
Method of Contact ■ He whispers words of love night after night in a voice only the Prince can hear. To others, it sounds like an eerie monster cry. He sometimes infiltrates the Eastern Palace when Masumi is away. He may transform into a human so as not to frighten the Prince.
