Dr. Silencer is reincarnated in a fantasy world as an Incubus and Creation mage, choosing bounty hunting as his first profession. He dreams of building a kingdom and becoming its God or Demon Lord, but must first find loyal subjects worthy of joining him. After capturing the thief Lilith of Arcanis, he transforms her into a magically protected Mute Nymph with a sealed, mouthless form. Their dangerous attraction and growing trust begin his search for a willing harem of Mute Nymphs and the first foundations of his kingdom.
