Agitate Halation Arc
Misaka Mikoto, while searching for Kamijou Touma in the School Garden, sees ten members of Shokuhou Misaki's clique in their winter uniforms leaving a fancy shop. Among them is the "ringlet curls girl", who is carrying a large brand-name gym bag over her shoulder.

Shokuhou Misaki Arc
After Misaki visits an SNS that their clique used using her account for the first time in three months asking cryptic questions, the Ringlet curl girl makes use of the vast information network of the Clique to track Misaki down. She later confronts Misaki as she prepares to enter the faculty apartment building that Kumokawa Seria currently resides in. Finding her, Misaki says that she did not give her any orders, to which the girl explains that she used the information network of the Clique to track her down after she acted suspiciously. She says that there are around 10 other volunteers waiting for her orders and that she and the others don't need to explain the details. Misaki tells her that she will give her orders but at the moment is not a good time, saying that the more people with her the greater the danger of being controlled. The girl accepts, but says that they should at least create an alibi for her leaving the dorm, to which Misaki agrees. As Misaki tries to continue onwards, the Ringlet curl girl frowns and calls to her again, but Misaki tells her to leave her alone for now, saying that the person she is about to meet is as dangerous as her, referring it to more as a request from her instead of an order. Finally, the girl accepts Misaki's request and tells her to be careful, to which Misaki says thanks.

After exiting the apartment building, the Ringlet curl girl appears before Misaki again, asking if there is something wrong. Misaki replies that she is fine though the girl says that if she is in some kind of trouble she need only tell them what to do. Misaki says that working alone is best for now, and says that if she really does need her she will not hesitate to give her an order. Misaki later leaves. Later, after discovering that her memories of Touma was real after all, and that the person made it so that Misaki would notice it, Misaki finally decides to confront her tormenter. She calls the Ringlet curl girl teling her that now she needs him. Misaki instructs her that she will be using them for her owwn benefit, asking her to gather together only those who are willing to be her pawns.

It is likely that the girl followed Misaki all the way to the Ground Geo where she would later confront Mitsuari Ayu. Later, when Misaki noticed that they would be in danger after the appearance of Five OVER Out Sider, she had the members of her clique quickly leave in order for not to get harmed. Moreover, it is also for them to take out the people who provides the Five OVER Out Sider's viewpoints that allow it to create its illusions, and then hijack the lenses to provide malicious feedback to Five OVER Out Sider, allowing the clique to take control of it. The ringlet curl girl is seen taking out one of these people, a man in a knit hat.
