A swallow +Anima named Lyra grew up in the same church as Cooro. She first appeared in chapter 49. When she showed up in front of Cooro and then flew away, he was shocked because the Lyra he knew wasn't a +Anima.
In chapter 50, it was revealed that Lyra had been jealous of Cooro. He had been a +Anima since he was a baby and received special treatment from the teachers. Lyra wanted to be treated specially too, so she sought a way to become a +Anima. Eventually, a person from the Royal Research Facility named Greena Aight implanted a Swallow +Anima into her, and she became one.
