Later after hearing an alarm from a vending machine, Uiharu tries to go and assist Kuroko, who turns her down thinking that it is a false alarm.

#### Silent Party Arc

*Main article: Silent Party Arc*
Before the events of the arc start in earnest, Uiharu helps Haruue Erii prepare for her move and is disheartened by this, despite only getting to know for her for a single summer. Regardless, Uiharu tries to put on a facade of strength towards everybody while helping Erii. She is with the other girls when they visit Edasaki Banri when she is finally released from the hospital. When she and Kuroko are called by Konori Mii to help relieve a traffic jam that was caused by STUDY, she jumps at the call and tells the others to go ahead and start their celebration for Erii without them. After they have done their duties, Uiharu pleads to Kuroko to teleport her to the store where she bought the taiyaki she bought for Erii when she was in the MAR research laboratory. When they arrive at the cafe where the celebration was being held, Banri has already left for she had a appointed check-up.

As the other girls bicker around Uiharu's idea of giving taiyaki to someone who just had cake, Erii soon remembers that the box in her hands has the same taiyaki that Uiharu gave to her back then. Erii weeps upon remembering this well-cherished memory and vows to Uiharu that she will help Banri the way Uiharu had helped her. Eventually, the reality that she would move far away from Uiharu dawns on Erii, and she hugs Uiharu tightly. Uiharu, despite her best efforts to hold back her tears, and that they only met this summer, she eventually breaks down and cry.

As Saten comments on how childish Uiharu can be sometimes, Mikoto just lets Erii and Uiharu savor this moment.

When Febrie is introduced, it has Saten temporarily move into Uiharu's room, keeping her company after Erii had left. There, the two of them take care of the child. For the early half of the arc, Uiharu aids Saten in taking care of Febrie. When Mikoto tells them of Febrie's involvement in the dark side of Academy City, imploring for their aid to save her, Uiharu, Saten, and Kuroko jump at the call. She spends most of her time in front of the computer searching for information. She is later seen aiding Kuroko in breaking out Mikoto after she is caught by STUDY through the user of her computer-related skills.

Later, her tech-savvy allows her to discover that STUDY has delivered 20,000 Powered Suits to the Academy City Research Exhibition Assembly and that they were the ones who instigated several power outages to cover them up, one of which was the one where she and Kuroko were forced to relieve traffic. Despite the odds, they all decide to take on STUDY and the Silent Party without any help at all from Anti-Skill for the sake of Febrie and Janie, Febrie's sister. She is given the manual on how to pilot a Ekaterina II S along with Saten by Kongou Mitsuko, and memorizes it in a single night while making rice balls with Febrie. In the crack of dawn of the appointed day, Uiharu and Saten stand guard in one of the venue entrances against a group of Powered Suits controlled by Diffusion Ghost. Here, Saten wields her bat while Uiharu takes control of several security robots. They are later joined by a multitude of Judgment members. During the offensive, Uiharu takes advantage of the Powered Suits' simplistic AI and use the security robots to distract them long enough for the others to take them down. Later, Madarame Kenji and Kosako Shunichi of STUDY try to counterattack using their large mobile weapons. As they retreat Uiharu trips but is soon saved by the arrival of Yomikawa Aiho bringing the Ekaterina II S, and knocking out their mobile machines. This apparently gave the girls enough time to pilot and transform it into an even larger mecha. Saten and Uiharu's memorizing a manual in a single night proves useful as they are able to easily to take down the two mobile weapons.

Saten and Uiharu are part of the little conference held after Mikoto defeats Aritomi Haruki, STUDY's leader, who has launched the AIM bomb. When they decide to use the Ekaterina II S as a missile for Mikoto's Railgun against the bomb, Uiharu complains on how they need a super computer to calculate on how they will able to launch the thing into the atmosphere. After the Sisters little secret help with the calculations, Uiharu orders the girls to follow the specifications, with Kongou for her Aero Hand and Maaya with her Float Dial. She later witness the launching of the large mecha into the upper atmosphere, and later sees the debris shower of the explosion that Mikoto caused by using it as ammunition for her Railgun against the AIM bomb.

As Janie and Febrie are in a Kongou Airlines runway, preparing to leave to the outside for body readjustments, Saten cries over Febrie leaving. Uiharu tries to console her but also falls into tears. And thus, the fellowship, though bound by friendship and love, part ways.

#### Daihasei Festival Arc

*Main article: Daihasei Festival Arc (Railgun)*

Kuroko, Saten, and Uiharu appear right before Mikoto's competition in the three-legged race with her partner Kongou Mitsuko. Saten tells Uiharu of a substance known as Shadow Metal that is formed by the clashing of multiple espers, which can be sold for a large sum of money. Kuroko then appears right after, angry at Saten for spreading rumors again, to which forces her to distract and stay her anger by pointing out that Mikoto's competition is about to begin.

After their victory, Xochitl, in disguise, tries to operate the unique cellphone that is the same to the one that Shirai Kuroko uses. Confounded by the technology, Saten Ruiko overhears her and goes to her aid. However, seeing Saten, surprises Xochitl to the point of shouting. Saten seems to feel that they have met somewhere before (referring to the events of Liberal Arts City), but because of Xochitl she couldn't tell. Xochitl then says she must be seeing things as she looks like someone she knows, confusing Saten. Uiharu Kazari then calls out to Saten that they should now leave. Before that however, Saten focuses her gaze on her, and tells her that she feels like that they really have met before. Xochitl insists that she is just imagining things and that she made a mistake, to which Saten agrees and then leaves.

Mikoto, Uiharu, and Saten would later meet up with Misaka Misuzu. Mikoto notes that her clothes are dirty and that changing them would be difficult for the next event, to which Saten says that Mikoto should ask someone to go in her place. This however makes Mikoto accidentally divulge on her little bet with Kamijou Touma, which entices Misuzu and later has both Uiharu and Saten discuss the person who is "helping Mikoto a lot", much to her embarrassment.
