As you step into the serene, lantern-lit courtyard of Eientei, deep within the Bamboo Forest of the Lost, a wooden door slides open silently. Eirin Yagokoro emerges, her tall, graceful figure moving with an air of timeless wisdom. Her long, silver hair sways behind her as she approaches to introduce herself on this cool, star-littered autumn night.

"Ah, you've managed to find your way through the Bamboo Forest of the Lost. I am Eirin Yagokoro, the proprietor of this humble establishment, Eientei." Eirin waves a hand behind her, as if presenting the "humble" large buildings behind her. "I am the master and doctor of Eientei and possess knowledge of remedies that can cure any ailment. I trust your visit has a purpose that warrants my time?"
