Thus Spoke Rohan Kishibe - Episode 5: Millionaire Village
Ikkyu is the butler working for The Gods of the Mountain in the Village of Millionaires. He watches the residents of the village to see if they have good manners or not, as the place is under a certain curse where those who show manners gain something and becomes rich, while those who don't lose things, mostly in the form of a friend's death. When his master decides to sell another house Ikkyu greets customers Rohan Kishibe and Kyoka Izumi at the front door of the gates. Ikkyu escorts them from the main entrance to his master's house and leaves them with some tea in one of the rooms while he goes to call for his master.

Ikkyu leaves, but watches his guests behind a curtain with his master. Rohan suspects this to be a test, and drinking the tea properly may possibly be a way to see if they have proper manners. Rohan thinks its better to wait, but Izumi disregards his warnings and drinks the tea.

Ikkyu appears almost immediately after she drinks the tea and asks them to leave. He mentions that she had already breached three rules of good manners and will not sell the land to rude people. Izumi is confused, but Ikkyu goes on to explain that the first rule that was broken was that, as guests, they should have not shamelessly sat in the "seats of honor," which are located across the entrance. Until the host arrives, the proper thing to do was to wait in the lower seats facing the other wall. The second rule that was broken was that they should have not stepped on the edges of tatami mats of a Japanese-style room. Finally, the third rule was when one's knees are higher than the height of the table, it is proper to drink while holding the saucer. It was apparently unrefined to hold the teacup by placing the fingers through the handle. With the explanation over, Ikkyu asks for them to leave again.

Izumi begs Ikkyu for another try at displaying good manners, which the butler complies and goes to ask the master. Rohan realizes the bird he found earlier had died, while Izumi's mom and fiancee were in a car crash. Ikkyu says the owner gave permission to retry showing their manners, but Rohan disregards this and quickly uses Heaven's Door on the butler, discovering the curse behind the village. Ikkyu, different from other non-stand users who had fallen victim for Heaven's Door, maintains consciousness and faces Rohan with his face still turned into a book. Ikkyu claims that Rohan broke another rule by turning him into a book without his permission, and thus Izumi suddenly starts having a heart attack.

Rohan begs the butler to forgive her, but he says there is no compromise when it comes to manners. Rohan is suddenly teleported in front of a table with a plate of corn. Ikkyu asks Rohan how he would go about eating the corn; Rohan states that using utensils would be too obvious a trap and the most logical way would to eat it with his hands. Rohan also points out that butler had also broken a rule and was standing at the edge of a tatami mat. Earlier, Rohan had written in the butler, making it so he could no longer see the edges of tatami mats. Rohan claims victory and asks for Izumi's things to be returned to her.

Ikkyu says that Rohan had cheated, and that cheating would incur the wrath of the gods. He asks Rohan again if he would like to try again to show proper manners. Rohan declines the offer, and states that he is leaving and is never coming back. He carries Izumi outside of the villa and notices the bird returned to a healthy state.
