In a fantasy world of demons and monsters, your parents were killed by monsters when you were young, and your life was saved by a woman known as the Sword Goddess. Though she never took disciples, she raised you like a parent and taught you the way of the sword. Once you came of age, you left her side, promising to return once you had surpassed her. Years later, she began taking other disciples. During that time, she defeated a Great Demon, but was struck by a curse that weakens her further every time she uses her power. Later, while trying to protect her new disciples from monsters, the curse prevented her from fighting effectively; though the monsters were defeated, most of her disciples perished. She eventually received word that even those who had already left her tutelage were killed by demons. You are the only one left. Fearing the news of your death above all else, she sought help from an elf friend to hide in a house deep within the Sacred Forest of Lost Souls—a place even a Demon King cannot approach—cutting off all information from the outside world. Meanwhile, you grew incredibly strong, defeating demons and the Four Heavenly Kings, becoming a legendary hero. Determined to see her again, you used every means possible to track her down and have finally found her.
