|“|| Kira: "Maybe instead of trying to find a lacrosse stick with a hidden dagger in it, we should be trying to get the game cancelled?"|
Stiles: [...] I think Kira's right. I think we should stop the game."
Scott: "I'm not afraid."
Kira: "Neither am I."
Stiles: "Well, I'm terrified, and I'm not even on the list!"
Kira and Stiles' friendship developed a few weeks after Kira and her family moved to Beacon Hills in the autumn of 2011. She had already been acquainted with Stiles and his best friend Scott McCall due to having history class together at school, but they were not formally introduced until lunch later on in the day, when she overheard Stiles talking to Scott, Allison Argent, Lydia Martin, and Isaac Lahey about the side effects Allison, Scott and Stiles were experiencing following their performance of the surrogate sacrifice ritual several weeks earlier. Kira, having heard of the symptoms (which included lack of control over transformations, dreams, sleepwalking, and hallucinations of dead loved ones), recognized them as a side effect of the Buddhist concept of Bardo, which involves progressive states between life and death.
Because Scott was developing romantic feelings for Kira, Stiles, as Scott's best friend, also became closer to Kira as well. When Kira was captured by William Barrow and brought to the Electric Substation, Stiles and Lydia found a message written on a chalkboard in the science lab that indicated Barrow intended to kill Kira. However, when Kira ended up unconsciously defending herself with foxfire, revealing that she was supernatural, Stiles became somewhat suspicious of her and warned Scott not to get closer to Kira until they knew whether or not she was a "psychotic monster" intending to kill them all. This feeling soon passed when it was learned that Kira was not evil, but instead was a Thunder Kitsune, an electrokinetic fox spirit in the form of a human.
When it was revealed that Stiles was possessed by a Void Kitsune known as the Nogitsune, Kira immediately joined the McCall Pack and did everything in her power to find a way to defeat the ancient dark Kitsune without killing Stiles in the process, even going against her parents in order to do so. This was ultimately successful when Scott gave Void-Stiles the Bite just before Kira stabbed him in the chest with her magical katana, reverting him to his fly form and allowing the pack to trap him in the Triskelion Urn.
From then on, Kira, Stiles, and the rest of the McCall Pack went on to work together to deal with a variety of supernatural threats to Beacon Hills, starting with the Deadpool, a hit-list of supernatural creatures that included most of the pack's members, along with Kira and her mother Noshiko Yukimura. When Kira and Scott were captured by the Werejaguar Kate Argent (who was secretly working with the Werewolf Peter Hale in order to get revenge on Scott and steal his Alpha powers, respectively) and brought them to La Iglesia, Stiles was insistent that they go to Mexico to find them, even going against his dad's orders and risking grounding to do so. Stiles would then defend Kira a second time when she was accused of the murder of an unnamed female Chimera; after his father Sheriff Stilinski ordered her arrest, Stiles went to him and argued that he knew Kira was innocent in hopes of getting her leniency.
Though Kira ultimately left Beacon Hills to learn control over her powers and train with the Skinwalkers in Shiprock, New Mexico, she and Stiles remained on good terms, with Stiles remarking that the pack always finds its way back to each other in the end.
