Fra Rarada

Secondary character from Gantz (manga).

Overview
Fra Rarada is the alien woman that Kei "kidnaps" in chapter 327. Kei Kourono forces her to help him and the humans to escape from the mothership. She tries to trick Kurono by shutting down her translator and calling in soldiers who end up attacking Kurono. Kurono ends up killing them all, so he forces Fra to take one of the costumes of the dead soldiers.

Although she was forced to help at first, she showed signs of empathy and compassion towards Kurono (Stockholm syndrome). She also seems interested in human beings, at least after meeting Kei.

It is also revealed that she is a young specimen of her kind, as stated by her mother when she and Kurono are in her apartment. Even though she says she is old enough to make her own decisions, she is likely to be a teenager, something like an 18-year-old human being.

Personality
She seems to differ from most aliens in the mothership in terms of behavior. Most of them are shown as ruthless and cruel, killing and eating human beings without signs of regret, while she communicates with Kurono (although forced at the beginning) and shows feelings that resemble those of humanity.

Death
She dies returning Tae to Kurono after he was transferred to a battle of war. His last words were "Please, do not kill us" for whom Kurono decides not to destroy the tower that maintains her spaceship.
