"None of the things I want can be bought with money"—Shannon, Alliance of the Golden Witch
Shannon (紗音 Shanon?), also known as Sayo (紗代?), is a servant working under the Ushiromiya family on Rokkenjima. She has a habit of making mistakes and blunders when she is nervous, despite being an extremely talented and hardworking servant. She thinks of Kanon as her younger brother and, like him, feels that she is inferior to humans, as she is only furniture. Despite this, she fell in love with George Ushiromiya and became engaged to him.
Kinzo Ushiromiya, after the death of his lover, Beatrice Castiglioni, became infatuated with his daughter, Beatrice Ushiromiya. Beatrice Ushiromiya strongly resembled her mother and Kinzo, in a state of madness, believed her to be the reincarnation of his dead lover. He forced himself on her and impregnated her. Beatrice Ushiromiya gave birth to Sayo Yasuda. In order to hide Kinzo's sin from the world, Kinzo and Genji Ronoue offered the child to Natsuhi Ushiromiya, who had been having trouble conceiving a child of her own. Natsuhi, distressed and angry at the offer, pushed the servant carrying the child, resulting in both the servant and the infant Sayo falling off of a cliff. The servant died upon impact with the rocky bottom, however Sayo miraculously survived. Unfortunately, Sayo sustained heavy injury to the abdominal and genital regions, resulting in severe mutilation.
After recovering from the incident, Sayo was taken under the wing of the Fukuin House and was given the name "Shannon". After studying at the Fukuin House, Shannon went on to become a servant of the Ushiromiya family. In 1980, Shannon fell in love with Battler Ushiromiya and the two made a promise to marry each other when they were older. However, later that year Battler abandoned the Ushiromiya family and didn't return to Rokkenjima until 1986. As a result, Shannon and Battler didn't see each other after making their promise for six years. Unfortunately, Battler had forgotten their promise by the time he arrived on the island.
While Battler was distanced from the family, Shannon fell in love with George Ushiromiya. The pair's romance was kept a secret as George's mother, Eva, would strongly disapprove of George being intimate with a servant.
Shannon appears as a well-endowed young woman with short brown hair and blue eyes. Her servant outfit consists of a black and white dress with purple lacing and accents, a short purple tie, and a white cap. Shannon appears to have the One-Winged Eagle tattooed on her left thigh.
When using supernatural powers, Shannon's abilities typically manifest as forms of defense, often consisting of various barriers that prevent or reflect attacks.
Legend of the Golden Witch
Shannon is first introduced as a servant on Rokkenjima. She is one of the few who demonstrates a genuine belief in the witch Beatrice. Shannon remains a fairly minor character until her relationship with George Ushiromiya is revealed and he proposes to her. George says he will determine Shannon's answer to his proposal by which finger she wears the ring on the following day. That night, Shannon sees golden butterflies in the guest house.
The next day, Shannon is found dead in the storehouse with half of her head split apart. George, who can't stand to see her in such a state, asks his father and Terumasa Nanjo to check if she is wearing a ring on her hand. The response is affirmative: Shannon was wearing the ring on the ring finger of her left hand.
Turn of the Golden Witch
Shannon's relationship with George Ushiromiya is greatly explored in Turn. Shannon's love for George is strong enough that she made a deal with the witch Beatrice to have the two be united through magic.
Requiem of the Golden Witch
Willard H. Wright interrogates Shannon regarding the strange existence of Lion Ushiromiya and asks for her to call Kanon so that he can talk with the two of them together. However, Shannon refuses to do so During Clair Vaux Bernardus's theater performance, Shannon frequently appears as Sayo Yasuda's only friend. Notably, no character other than Sayo ever speaks directly to Shannon during this time.
Twilight of the Golden Witch
Shannon is the eleventh person to pose a quiz to Ange Ushiromiya during the Halloween party. Her puzzle centers around the flavors of various foods.
- Shannon's breasts are fake. This is part of a plot hole in the Umineko no Naku Koro ni anime as Shannon is depicted with real breasts in the anime and the anime's promotional art.
- Like the other servants from the Fukuin House, Shannon has the character "音" in her name.
