Description
Ikkyu is a young boy who serves as the butler for the mysterious owner of a villa in a secluded, wealthy village. Physically, he is a small child with an oversized head, large globular eyes, and unkempt hair styled with a braid forming a crest on top. He is always seen in a dark butler’s uniform complete with a bow tie and checkered trousers.

Ikkyu’s personality is defined by his absolute and emotionless dedication to the strictest codes of Japanese etiquette. He believes there is no compromise when it comes to manners and shows no concern for those who suffer after breaching rules, even as subtle facial expressions might suggest otherwise. His entire motivation revolves around serving his master, known as the God of the Mountain, by observing and testing potential buyers of the village’s properties to ensure they demonstrate proper conduct.

In the story, Ikkyu’s primary role is as an antagonist and gatekeeper. He greets the manga artist Rohan Kishibe and his editor Kyoka Izumi when they arrive to view a house for sale. After serving them tea, he secretly observes their behavior with his master. When Izumi fails his test by committing three distinct etiquette violations, he coldly asks them to leave and explains that the land will not be sold to rude people. It is revealed that the village is under a curse where those who lack manners lose something precious, and Ikkyu enforces this rule without mercy. When Rohan uses his Stand, Heaven’s Door, on him, Ikkyu displays an unusual resistance, remaining conscious and aware, unlike most non-Stand users. He engages Rohan in a battle of wits over proper corn-eating etiquette, but is ultimately outsmarted when Rohan exploits a rule he himself had broken after writing a command into him. His key relationship is with his unseen master, the God of the Mountain, to whom he is completely loyal. His role is primarily static, serving as the unwavering instrument of the village’s curse. As for notable abilities, beyond his encyclopedic knowledge of formal etiquette, he can enforce the supernatural curse of the village, causing people to suffer immediate, grievous consequences for their infractions. He also demonstrates a unique resilience to Heaven’s Door, retaining his faculties where others would lose consciousness.
