Touma coined the nickname Biri-Biri and whenever the two meet he usually calls her that, even after his amnesia.
To most people, she is considered a 'proper lady', but in reality, she's short-tempered, prideful, and has an improper attitude with some slight tomboyish tendencies and insecurities- a fact few people know of.
