In her past life, she was the Star Witch who swept across the continent, only to be tragically betrayed by the joint backstabbing of the Nine Great Witches, turning overnight into Lina, an apprentice witch so poor she gnaws on black bread! She intended to lie flat and slack off waiting to die, but she picked up the soft and cute little apprentice Annie, and got to know the noble maiden Xibil. Afterwards, they rented a place and lived together, taking on commissions, opening tutoring classes, and supporting one another. Yet the covered-up history reappears, with cult conspiracies and ancient prophecies following one after another. Lina, who single-mindedly wants to be a lazy slacker, has no choice but to join hands with her partners to resist the impending disaster.
