A veteran of the Russian Revolution, Maria is the only member of the Hanagumi with prior experience of military tactics and warfare. This experience was why she was chosen to be the original leader of the group. However, though her struggles in Russia had left her an expert marksman and skilled tactician, she also became coldly logical and unwilling to interact with others on an emotional level, which led to being labeled "Kazuar" (in anime it's said that this name means "phoenix," but actually it's a bird, but its closest relative is ostrich). After a series of set backs, it was decided that Ichiro Ougami should replace her as leader, with Maria remaining as his second. After an initial period of friction between the pair when Ōgami arrived, Maria's attitude began to turn slightly, though she still remains the most coldly emotional of the group. Sakura looks up at Maria very much at the beginning.
