Helena von Bähbem is the niece of Ernst von Bähbem. A childhood acquaintance of Makoto Isshiki and Itsuki Kisaragi, she serves as the second in command in the Bähbem Foundation. In addition to being a childhood dabbler in witchcraft, she was a potential instrumentalist, but passed the ideal age without realizing her potential. This makes her jealous of Quon and others that might succeed in tuning the world. She eventually allows Ernst von Bähbem to take over her body.
