In the land of Aglia; the Demon King's Kingdom, there was a group of magic users who have served the Demon for centuries. These Witches were easily identifiable by their natural silver hair and shining golden eyes. Despite having human form, Witches are the result of a human and a Daemon, as a result, their magical affinity soars high above human limits and can equal Arch-Lords in strength.
Their clan is split into two factions: the Crows; who focus primarily on magic training and lore-keeping, and the Ravens; who try to master the art of combat and swordsmanship. Each faction has a leader. The Crows serve the Reaper, who has mastered the most magic arts. The Ravens serve the Nightingale, a complete master of combat who could rival the Demon King in terms of technique. Both factions however, serve the Blackbird; one who has completely mastered both combat and magic to become the ultimate Magus.
The title of Blackbird has been indisputably held by the Lukaefer family, who are direct descendants of the original witch. Their tree began with Ishtara Lukaefer, a woman who went above and beyond normal expectations as a witch by formulating a new Magic Tree: the Chronus Tree. She had developed it to a point where she could skip or rewind time itself by about five seconds. Her research was considered too dangerous by the other families, so they refused to learn it, leaving Ishtara to construct it herself. In five months, she had developed the second tier, allowing her to slightly bend reality.
One day, everything changed when the clan's headquarters was approached by two women. One was a black-haired girl with shining red eyes wearing a black dress. The other was a red-haired woman with blazing scarlet eyes and crimson armour. The red-haired woman seemed to terrify the Ravens on guard. Her Mana level seemed to surpass even Ishtara and possibly the Demon King, and the other girl didn't seem too far off.
"You have been accused of Sin," the red-haired woman spoke in a regal voice, "Of the Forbidden Art: Necromancy. I, Kora Lilith, shall purge you and free the trapped souls."
Without a second thought, she had darted around at a near impossible speed and tore up the guards all around the camp, the walls turned crimson with blood. She and the girl behind her sped around the camp and killed every witch they found. When it was over, nearly everyone was dead. The once great Witch Clan was no more, save for the children of two families. The daughter of Ishtara, and the daughter of Ophelia Satania, the Nightingale.
After five-hundred years, only three known witches remain. Mizu Satania, the Reaper. Miu Satania, the Nightingale. And the Blackbird, Astil Lukaefer. There is a fourth, far stronger witch out there, but she hasn't been found yet.
After so many years, Astil no longer feared the original terror that took the clan. She had taken Ishtara's research and fully developed the Chronus Magic Tree. Her power now potentially even surpassed the Goddess Reinha, but she has no desire to assist the Demon King, only to research and develop more spells. Her only desire was to see her daughter once again, the daughter that was taken from her. She was relaxing one day in a small town when she spotted something. A silver-haired girl who was walking with a black-haired boy. From that point on, she had no doubts left in her mind. When she was about to follow however, she noticed that the Twins had vanished.
