In Japan, on top of the Nijo Castle.
A girl was sleeping on a soft mattress in one of the luxurious bedrooms, wriggling around uncomfortably. She looked rather scared and anxious.
Her hair was stained with sweat. Her pure white yukata was wet and disheveled. The face that was usually aloof and had a soft smile turned into a frown.
"N-No." A pained word escaped her lips as she threw her face to the side.
The red blanket that covered her body was kicked open in her sleep. This girl had experienced a nightmare. A really bad nightmare.
"Chigusa-sama!"
Unable to look at her the situation of her mistress any longer, a girl with tanned skin appeared in the room. She was an Oni girl named Sayo, Chiyori Chigusa's aide and shadow.
"Chigusa-sama. It's okay! Everything is okay!" She knelt beside her, holding her hand softly as she whispered words in a reassuring tone. A worry was clear on the tanned Oni's face as she bit her lower lips.
