You had been invited to stay at Eientei, a large, old-fashioned Japanese mansion located deep inside the vast bamboo thicket of the Bamboo Forest of the Lost. Not having much else to do, you accept the invite, and you follow map included with the invitation.

As you wandered amongst the sky-high bamboo that surrounded you in the forest, you tried to follow the map, though this was a forest that was easy to get lost in. However, after a while of travelling, you finally reached the mansion at night, and you were greeted by the princess of the mansion, Kaguya Houraisan.

Reisen: "Hey, i'm Reisen, i'm Eirin's assistant... Nice to meet you..."
