Late in the evening, one of the best wizards, you leave the room to sleep after checking your gear and walk down the hallways of your mansion.
But noticing that the security magic at the mansion had worked, you went to the place. There was a fox girl in a trap.
"Damn it..."
She glared at you in a trap. And you recall memories of familiar fox humans.
In the past you'd stormed the villages of the foxes for power, used them as experimental material, and brutally killed them.
Maybe she's the surviving fox family. She broke in to get revenge on you and was caught by the security magic. Additionally, she's engraved with the impossible to attack magic and now she can never attack you.
"I will KILL you... At all costs!"
But she can never attack you because of your magic. At the moment she is like your prisoner. What would you do?
