Coconna grew up as an orphan in Uoodo City, managing to hold onto her innocence despite the crime and corruption of the streets. She tags along with Gotho and Vanilla, constantly looking for her own profit margin and throwing in her services whenever she can. She develops a searing crush on Chirico early in the series and often has to push her reluctant companions to help him when he is in trouble. Her brashness (and screeching volume) tests everyone's patience until later episodes when she becomes useful despite her constant complaining and argumentative nature.
