|Season||Guardian Angels Of The Stars|
Averill was the last 'marionette' to be created by the fused power of Dolores and Brek. She was created to represent the enthusiasm towards a battle and turned out a little sadistic. Since Averill has the youngest appearance of the whole group, she gets special treatment by the others and, even if her Decxious have been defeated by the angels, she's never really been punished for not doing a good job. Averill was usually kept out of the planning and decided the next move, so she had a lot time to walk around the town and find someone to play with.
- Brek: Besides being her "master", Averill looks up to Brek as if she was her older sister. In fact, she even calls her older sister, and is hardly ever heard to call her by her name. Yet, it doesn't seem to bother Brek at all. All she seems to care for is whether she's doing what she's supposed to or not.
- Dolores: Similar to how Averill acts towards Brek she also acts towards Dolores. However, unlike Brek, Dolores responds to Averill. Both act towards each other as if they were sisters and Dolores seems to be pretty concerned of Averill's well being.
- Averill shares her seiyuu with Yukine Chirs from Symphogear.
