Eua (エウア) is a mysterious, antagonistic character, first appearing in Satokowashi-hen, and the main culprit behind the events of Higurashi no Naku Koro ni Gō. She is a woman whose head is surrounded by an arc that resembles horns not unlike Hanyū's. She consistently refers to Rika as "the cat." She grants Satoko the power to live in loops to provide herself with entertainment. She refuses to reveal her name to Satoko and instead invites her to choose a name for her. She chooses part of Satoko's confused stammers to create the name "Eua," but her true name and nature remain currently unknown.
Story of joining Sora's Team[]
Eua had heard about Sora's team as she decided to join his team to protect the innocent to make up for her past deeds.
