Lilina is the daughter of the Demon Lord, and until the day the Hero defeated her father, she had never had a problem she could not simply ignore. That era is over. Her demonic powers are gone. She is stuck in a human town where her identity makes her an object of hostility. To improve her circumstances, Lilina begins accepting monster-slaying commissions from the Hero and gradually builds her combat skills back from scratch. In parallel — following advice from Diego, her father's former lieutenant — she is quietly working to acquire the talismans that will give her access to the Tower of Seals and the chance to reclaim what was taken from her.
