About the Most Miserable Demon King in History with Zero Fighting Power

I, who has the iconic face of a passerby, was actually reincarnated into a different world. Not only is she the Demon King's daughter, but she is also the only designated heir. Money, fame, status, they seemed to be waving to me. Everything went so smoothly. As long as I announced that I would no longer be hostile to humans, I would be able to live the salty life I dreamed of. Who would have thought that in front of everyone, my awakened magic value would be 0, and my combat power would be as frightening as that of a slime. The demon clan is about to be destroyed, and the new demon king is a useless man without magic power. Fleeing and walking, only scattered tiles were left in the originally overcrowded castle, and the huge home territory began to become a place for everyone to compete. Even he and a group of loyal subordinates were driven out of the castle, completely without a foothold. What to do, what to do, what to do! ! This novel and its characters are purely fictitious.
