Berune

Berune is one of the orphans from the Fukuin House who worked in the Ushiromiya household. She arrived with Asune after Runon, Renon, Sanon and Benon left. She has brassy hair in two short drill pigtails, a fair skin tone and big gray eyes. Her clothes are the same as those of the female Ushiromiya servants. She, along with various characters, were questioned by Zepar and Furfur as witnesses to describe what Yasu was like before becoming a witch. She was really confused by the prank with the key Yasu played on her and started to believe in the Witch Beatrice. However, she was harshly scolded by her friend and coworker Asune because of that. Later she became a basis for the Demon of Gluttony, Beelzebub. (Source: Umineko No Naku Koro Ni Wiki).
