Winnie Emex (ウィニー・エメクス, Winī Emekusu), also known as Winnie the Witch, is a witch owning a bar nearby the Rimdarl Kingdom.
Winnie appears as a young female human, but in reality is hundreds of years old. She has a medium long green hair and purple eyes and wears glasses. Being a witch, she usually wears a witch outfit.
Winnie was seen as a mysterious individual who helps others, with condition on her terms. Such as when Sally asked her to teach her magic, she asked for a payment of one million. And when she let them stay at her bar, she told them they have to clean it as return. She is also somewhat playful, as she likes to surprise Sally by suddenly appearing from behind. She also taunted Todoroki, by smiling at him frighteningly, when the oni demands to tell him who she was.
Winnie sneaks into the Rimdarl castle and checks their archives. She then sense intense energy and teleports away, while taking three more people. As the energy was an Ogre Blast, which obliterated the kingdom, Winnie asks those that she saved to work for her, but soon after they ran away from her.
Using her crystal ball, she watches over Saltherine Aldarake and her group and knew they were coming to her bar. She makes them order a drink and explains her reason for saving the people and what happened with them. Sally asks Winnie to train her and teach her magic. Winnie agrees on three conditions: keep it a secret, do as she says and pay one million. As Sally doesn't have that much money, Winnie agrees on discount for every penny she has on her, but Sally doesn't even have a single penny. As its getting dark, Winnie offers Sally's group to stay for the night instead of paying, they can clean the rooms.
As everyone goes to sleep, Frau visits Winnie, who had expected her as its been three hundred years since they last seen each other. As she had seen Frau uses a mallet, she made a new one for her. Frau asks Winnie to teach Sally magic, but Winnie doesn't budge on the price, however, states she can be paid later.
