.: Cooro | 11 | male | +anima | 4'8" | single multi ship :.
Cooro was found in a church as a baby, already with his crow wings. In the town of Lilt, where he was born, Cooro's mother died while still pregnant with him. The custom in Lilt is to have the body of a deceased eaten by the crows and Cooro, somehow still alive inside his mother, broke free of her body and drew in a crow Anima out of longing to chase after her spirit.
Cooro was raised at the church, then taken to the research facility in Astar. Here, he befriended Fly, one of the researchers. Fly asked Cooro if he could take his Anima through 'Anima Removal Surgery' when he was older, and Cooro, who was very young and didn't understand what he was promising, said yes. Fly sent Cooro out to find more +Anima to preform the surgery on, but Cooro forgot the mission on purpose, only remembering that he was looking for other +Anima. The reason for this is he preferred to keep traveling with the others.
When he eventually returned to Astar, Cooro remembered his promise and agreed to let Fly take his Anima, much to the dismay of his friends who refused to go through the surgery. Although the transfer was successful, Cooro felt lost afterwards and wandered back to the place in Lilt where he'd become a +Anima. He experienced a deep longing for something in his heart that he couldn't obtain and grew his wings back. He made to fly away, but his friends came to stop him, and his void was filled with their friendship. It is certain that his Anima reverted from Fly, and back to him.
