|Behind The Scenes|
|First Appearance||Episode 13|
|Last Appearance||Episode 14|
Bertha was a former Viennese opera singer who had an addiction to tobacco. While she was pregnant she stopped smoking, and later gave birth to a baby girl. She loved her child deeply, referring to her as an "angel" and describing her as "unbelievably adorable". After Bertha had given birth, however, she resumed smoking, and one day her daughter took some tobacco from the table and stuffed it in her mouth. The little girl died as a result. Although Bertha's obeisance is to stuff anything in her mouth and choke it back up, she has chosen tobacco, possibly as a reminder of her daughter.
Sound Resonance Manipulation: She is a Contractor with the ability to control the resonance of sound. All objects vibrate at a particular frequency. When she projects and hits an object with the same frequency, the vibration begins to resonate throughout the object, strengthening until the object shatters like glass. The target she chooses can literally be anything, including vital organs. By matching the hearts resonance frequency, she can cause a heart attack.
- Obeisance: Bertha's obeisance is to ingest something and then vomit it out, although her preferred item is tobacco due to the incident with her daughter.
Part In StoryEdit
Bertha appears in a meeting point to meet up with her partner Itzhak. After killing a person following them, Itzhak arrives and clears the area of the specters dolls sent to spy on suspicious activity. One of the specters turn out to be Yin's. The two trace down Yin, and are about to capture her, but for the interference of Hei. Before an all out battle can start, they all manage to escape. Yin is taken by Gai, Kiko and her former teacher Elis. Itzhak and Bertha manage to track down Yin yet again, this time to an abandoned building. Hei battles her, and she apparently kills Hei by causing a cardiac arrest. Hei however restarts his heart by sending an electric shock to his heart. While she is surprised, Hei catches her with a wire and sends an electric charge along it, electrocuting her. She dies staring at the specters that Itzhak releases as he too dies.
