This article is about a character in Umineko no Naku Koro ni.

Masayuki Nanjo (南條 雅行 Nanjō Masayuki) is Terumasa Nanjo's son and a recipient of a mysterious letter from Beatrice. He only appears in Alliance of the Golden Witch.


Nanjo's son. Inherited the Nanjo Clinic. Unlike Nanjo, he seems to be a more sobered, indifferent person.

After the rampage surrounding Rokkenjima, he grew to completely despise the press, and he never spoke again of what happened around that time.

He once had a daughter afflicted with an incurable disease, but unfortunately, she wasn't able to live out her natural lifespan.


Masayuki wears a white coat over a white shirt and green tie. He has gray hair.


Masayuki is very jaded when it comes to matters surrounding the Rokkenjima Massacre, as he has been faced with many people trying to interview him about it.

Role in the Story

Alliance of the Golden Witch

In 1998, Ange goes to interview relatives of people who died in the Rokkenjima Massacre, with her first stop being Masayuki. Masayuki reveals that, some time after the Massacre, he had received a letter containing a PIN number, a bank card, and a set of keys to a safe-deposit box; this letter was arranged such that it listed Terumasa as the sender and went to an address that didn't exist, thereby causing the postal service to return the letter to its home address.

After investigating these items, Masayuki was presented with a case containing a massive amount of money. Masayuki rejected this money, finding it to be very suspicious. Ange compares the handwriting on the letter to that in Maria's grimoire and starts to piece something together.
