Ulrike Jenni is a German dubbing and voice actress, not a Japanese anime voice actor. She was born on April 7, 1969 in Munich, Germany. She began her voice acting career through a former classmate and friend, Sabine Bohlmann, who was already working as a dubbing actress while in school. Jenni accompanied Bohlmann to a studio to watch the process and unexpectedly was asked to voice a role in a high school series when another actress had been sent away early. As the series progressed and her character grew in importance, she was retained in the role. After finishing school, she completed formal training in acting, dance, and singing.
