Preatians (プリーティアンズ, Preatians), also known as "Nekomata" (猫又, Nekomata), or simply just "Neko" (猫, Neko) are a group of mutated Arechians who mutated into humanoid-cat-like race during the end of the First Era on Patriam. The former humans soon accepted and embraced the change.
They basically like exactly human, except, they have have tails, ears and slit pupils. They also have control over Reishi, making the Preatians among the only species to know how to do so without training, or being gift by from Solomon. They can also make their nails to become sharp, thus making them claws.
