Fra Rarada

Fra Rarada (フラ・ララダ, Fura Rarada) is the alien woman that Kei "kidnaps" in chapter 327. He forces her to help the him and the humans escape from the Mothership. She tries to trick Kurono by turning off her translator and calling for soldiers who end up attacking Kurono. She seems to differ from the majority of the aliens in the mothership in terms of behavior. Most of them are shown as ruthless and cruel, killing and eating human beings with no signs of regret, while she communicates with Kurono (though forced at first) and demonstrates feelings that resemble those of humanity's. She is also revealed to be a young specimen of her kind, as stated by her mother when Kurono and herself are in her apartment. Although she says that she's old enough to make her own decisions, she is likely to be a teenager, something like a 18 years old human.
