, or for short, is a demon that serves as the baby demons maid.

Story
Hilda originally came to the human world by command of the demon lord to raise his son, Kaiser de Emperana Beelzebub IV, to be a 'good' human destroyer. Beelzebub however got so attached to Oga Tatsumi, that she now observes him and his progress in being the future demon king's parent.

Character
Hilda has a very calm character at times, even in fights and dangerous situations which she uses to lure Oga back into fighting.

Appearance
Hildegarda is depicted as blonde with green eyes, and is well endowed. Her clothes are mostly black with white quillings and thus resemble Lolita Fashion.

Weaponry
Her main weapon is a swordstick-like umbrella again fitting her victorian era theme. However she rarely draws the sword, especially against weak opponents she refuses to do so.

Conveyance
Despite the fact that she is naturally just as fast as strong she is as a demon, Hildegarda rides a giant bird-like being named Ak-Baba
