The Red Data Book is a document that details those species of animal that are considered to be at the highest risk of extinction, even amongst those already considered endangered. As such, their protection is of the highest priority. In this vein, and for the purpose of the series, a Red Data Girl is one whose rarity makes them an anomaly within the world. They are to be guarded with vigilance, lest those who would abuse and misuse her ever managed to take her. At least, that’s what the series title card taught me.
