Esther Rosenthal

Classification: Magician
Ability: Necromancy
Affiliation: Rosenthal Family

Esther first appears while being pursued by DA. While escaping them, she enters a certain hospital and finds herself in Accelerator's room. She attempts to ask him about Last Order, however Accelerator doesn't notice her due to using his power to deflect sound away from him while reading. While she tries to get his attention, her pursuer catch up with her and manage to subdue her. She is later tied up with several belts and gagged. Despite her bonds, she manages to get out during the scuffle between the Anti-Skill and Accelerator who has come to take her away for questioning as she carried a photo of Last Order.
