@EvelineClariss It's about the approach not how many girlfriends she has. Unlike Mitama, she doesn't seem like the type that would try to get her girlfriends (Mifuyu, Iroha, Tsuruno, and Momoko) to do stuff they don't want to do.
Brigitte is definitely a bottom, yeah.
Also my Swedish brain keeps wanting to call her Birgitta, which is the actual real Swedish name that's the closest to the really weird-sounding Brigitte. Nobody here would name their kid that, not even a weird future dwarf. American writers etc.
