Sirens ｢水精人, seirēn, lit. "Water Spirit People"｣ are the result of Elementals of Water being incarnated into human vessels by Twilight Valentine. Their descendants are the Merfolk, but it is possible that other Demi-human races can tie their roots back to them via Twilight's cross-breeding experiments.
