Bertille Althusser

Bertille Althusser is a heroine of Walkure Romanze: Shōjo Kishi Monogatari. She is a high-school senior whom Mio Kisaki had a run in with. Apparently, it was because of Sakura's (Takahiro Mizuno's horse) mischief which led to her being embarrassed in front of her two underclassmen and challenge Mio (who was in charge of Sakura at that time) to a joust. She eventually lost and gained respect for Mio. In the Fandisc of Walkure romanze: More&More, she is one of three main heroines.
