It took a long time for the owner of the lantern house to fill a bathtub for you up with water, as you start to get worried that something bad might happen, like the suit of armor coming to life. You could hear the sound of water running from upstairs, just after you begin to get drowsy from the rice cakes you've eaten.
You then hear the house owner come back downstairs, once the water running sound stops. "Alright, Kip," Harumi's voice came from upstairs. "The bath is ready." You try to find the stairs, and see Harumi standing on a wooden staircase, carrying towels. "Just follow me, child," Harumi explains. "I'll get you cleaned up, and have you ready for the guest bedroom tonight." "Okay?" You ask, and follow her upstairs to the bathroom, where two other doors were located on the opposite end.
Harumi opens the door, and reveals a room with a bathtub full of water, and you see a bunch of balls of soap next to it, along with a couple of candles. You take off your clothes, and then get in the tub filled with water, as you take the balls of soap, to wash.
