Daihasei Festival Arc
In the days leading up to the Daihaseisai, Ringlet curl girl is having tea with Shokuhou Misaki and two other members of the clique. She scolds Shokuhou who is attempting to eat a second eclair. Shokuhou then uses her mind control and tells her to go eat 20 eclairs as quickly as possible.

September 20, the second day of the Daihaseisai: She and the rest of Shokuhou Misaki's clique are charged with watching over Misaka Mikoto. She sees that Mikoto has a Gekota phone and reveals that she has one too. She says that she managed to acquire a rare mail order limited edition Gekota strap from that year's M-fes. She tells Mikoto that she will give it to her if she gives her all in the day's events. Mikoto becomes very excited for a moment, but then realizes that this is all a trap and that Ringlet curl girl is frighteningly skilled.
