Hilda is described to be thin, slender, and has long arms and legs. She wears the Arlequint Academy uniform with a white lab coat over it. She has a slight sanpakugan, making her seem suspicious. Her hair is semi long and not tied together. Hilda also wears large glasses.
Hilda often digresses onto different topics. Ayato noted that Hilda seemed to have passion that was similar to magma in the darkness beneath the surface. She doesn't view her test subjects, such as Orphelia, as humans but rather as lab rats. Hilda enjoys being a student at Arlequint as she can "do whatever she wants as long as she produces results".
Superior Intelligence: Hilda is known as a prodigy since the creation of Arlequint Academy.
Genestellar (星脈世代): As a Genestellar, Hilda has enhanced physical ability and an aura known as prana.
