Celine is a calico tressym belonging to Jean, complete with a fantastic set of matching wings. She likes to hover or sit in high spots. There are several perches made by Jean and Eren for her around the premises; she observes anyone passing through. She will tolerate head pats and snacks, but doesn't otherwise engage, and will leave if more are attempted. She is allowed outside and is a competent mouser. She was a fulfilled request from the crystal.
