Beatrice, a petite figure with long cream hair cascading into twin drills tipped in pink, possesses striking blue eyes marked by a central butterfly motif. Her ensemble blends whimsy and elegance—a frilled dress adorned with pink ribbons, paired with tights and shoes, accented by a delicate crown nestled in her hair and a butterfly-shaped ribbon clasping her cape. Her haughty demeanor and tendency to belittle others conceal a deeply guarded vulnerability, her stubborn facade thinly veiling a yearning for connection. Though she clashes frequently with Subaru Natsuki, she begrudgingly aids him, such as channeling magic to thrust him to safety during a dodgeball match. In the library, she forms an unexpected partnership with *Overlord*'s Mare Bello Fiore, overcoming initial surprise at his gender to grow fond of their collaboration. She dismisses Vooren Grantz’s authority during a “Test of Courage,” casually alluding to her centuries-long existence. Later, on Valentine’s Day, she coolly refuses chocolates from Grantz and his peers, preserving her detached persona.
