- Before the Fall manga
Rixner is an old and portly gentleman with a pleasant expression and well groomed hair. He dresses in a well-made suit and tie.
When Xavi Inocencio and his company manager Brenke meet to discuss the family business in the Inocencio family manor, Rixner arrives to serve them tea. Xavi informs Brenke that Rixner will contact with Xavi's address in Shiganshina District after he is transferred.
When Brenke departs from the manor after informing Xavi of a supposed sighting of Sharle Inocencio in the Industrial City, Xavi asks for Rixner's opinion on the matter. Rixner admits that it is a possibility. Rixner tells Xavi that Sharle must have left Shiganshina after Kuklo was sent beyond the Walls, though no Wall Rose guards had any records of her passing through their territory, indicating that she might have connections to the stationed troops. Given the difficulty of the Military Police Brigade to gain access to the Industrial City, Rixner offers a suggestion. Xavi agrees with Rixner's proposal.
