ベアトリス・イヴォンヌ・フォン・クルデンホル
from The Familiar of Zero
Origin
Grand Duchy of Guldenhorf
She is a daughter of the Grand Duke de Guldenhorf, thus a princess of the Grand Duchy of Guldenhorf. A typical noble and a rather snobby individual, she uses her position of power as Grand Duchess to bully other students. Beatrice is followed around by three other girls (clique group) who help her bully people and are generally agreeing with her due to her title.
The Familiar of Zero
Meet Louise, a budding magician. The students at the Tristein Academy call her "Zero Louise", due to her current record of zero successes with magic. In fact, her magic tends to go spectacularly wrong. Now, as an important test of her aptitude for magic, she must summon a familiar to be her servant. At this critical moment, she summons up all her magic and wishes for a familiar that is "devoted, beautiful and powerful", and gets... Hiraga Saito, an ordinary Japanese boy. It's difficult to say who is more surprised and dismayed, but the rules don't allow for second attempts. Louise is stuck with her strange familiar, and he with her.
