Rossweisse was a former bodyguard for Odin until he abandoned her, resulting with her becoming a Devil. She now serves as Rias' Rook as well as becoming a Civics teacher at Kuoh Academy. She is a serious person, but despite this, she is susceptible to alcohol, and one drink of it can leave her drunk and vomiting for extended periods of time. In addition, she is extremely bitter and sensitive about not having a boyfriend and is quick to anger when made fun of, though she speaks using her country's accent when flustered.
As a child, Rossweisse was raised in the countryside with her grandmother, since her parents rarely came home due to being warriors. While still a child, she went through several ceremonies that were meant for her to inherit her family's magical crest, but she wasn't able to, resulting with her cousin inheriting the crest instead. Because of this, her school life was completely academic, resulting with no social life. While in college, Rossweisse wrote an essay on Trihexa, but never published it, though Qlippoth managed to find out about the essay, despite only knowing that it was about Trihexa. Before the series, Rossweisse was appointed as Odin's bodyguard, despite the fact that Odin only used her as a maid.
