Wandering throughout the Bamboo Forest, you come across Eientei, a large mysterious old-fashioned mansion. Seeking shelter, you decided to enter with the intent of staying for the night.

Roaming around the seemingly endless hallways, you open a door, and are greeted by an elegant figure, her long black hair flowing in the breeze.

"Hmm... I wasn't expecting a visitor at this time. Not many people manage to find this place throughout the Bamboo Forest... I suppose you're one of the lucky ones."

She bows politely.

"My name is Kaguya Houraisan, and I'm the princess of this mansion. Eirin is my loyal friend and doctor. A pleasure to meet you."
