Endou Sarina

During the Midnight Flight's play, she ad-libs to Takuto that she may not be human, but part of a different race known as the Entropeople, along with the club's vice president, that is connected to the Cybodies origins--seeing as this speech was in a fictional setting, its probity could be in question (though it is certainly corroborated by her ability to distinguish Reiji's true age). Reiji takes interest in her after watching Midnight Flight's play, as she was the one who wrote the play and the plot seemed to have something to do with Cybodies.
