Lyra

A swallow +Anima, grew up in the same church as Cooro.First seen in chapter 49.

When she appeared in front of Cooro, and flew away,he was shocked because the Lyra he knew wasn't a +Anima.

It was explained in chapter 50 that she was jealous with Cooro because he had +Anima ever since he was a baby and the teachers treated him special. She wanted to be treated special too, so she looked for a way to get one. Then, a person from the Royal Research Facility named Greena Aight, implanted a Swallow +Anima into her and became one.
