Kira

Kira is a 16 year-old girl and one of the girls that Austin has crushed on. She is the first person in universe to think Ally and Austin like each other, and refused to date Austin because of this. However, she eventually was convinced, and had so much fun on their date that she officially became Austin's girlfriend. She is Austin's longest-lasting crush, since he first liked her in Ferris Wheels & Funky Breath (except her breath), went out with her in Girlfriends & Girl Friends, and is still dating her up until Chapters & Choices, unlike Cassidy, who he temporarily liked in Diners & Daters, and Brooke, who he dated in Magazines & Made-Up Stuff. However, it is likely that once Austin goes out with Ally, they will last longer than Austin and Kira.
