Hilda is one of the antagonists of the story in Under Night In-Birth. She is one of the founders of the faction, Amnesia. Her main goal is to become a Re-Birth and plans to shape the Hollow Night in her own image. She is also known as Paradox by some. She seeks out Hyde (whom she calls "Insulator Boy") for the Insulator he posses. In Hilda's ending, she ends up killing both Hyde and Linne, acquiring the Insulator.
