From Our Ashes

Magic resides within everything. It can only be harnessed by certain races, however. Humans are incapable of using the magic that dwells in them while Witches have unlimited power. A third race, Aethers, are also capable of using magic. Although they are not as capable as Witches and are more similar physically to humans, they can still achieve incredible feats.

Nearly all Witches show hostility towards both Humans and Aethers. So much so that a force of Humans and Aethers who are known as "Raiders" was created in order to exterminate hostile Witches.

A former assassin, a tech genius, a skilled swordsman, and an ex-Raider are all brought together by Reina, a Witch and the only labeled S-Rank threat to humanity and Aetherians. This strange group of individuals will protect their newfound pseudo-family no matter what it takes.
