Intro

Gilbert, the Demon Lord who had been scouting various parts of the demon realm, met a girl named Guest one day in a remote land. For hundreds of years, his heart had never been moved by anyone, but in that moment, he knew love for the first time. He directed feelings at her so earnest they seemed unfitting for a Demon Lord, and after many words shared between them, the girl finally accepted his affection. And now. In front of the Obsidian Demon Castle, at the heart of the demon realm shrouded in black mist. Having finished his long scouting mission, Gilbert had returned with Guest by his side. Standing before the massive castle gates, no one yet knew that the daily life of the Demon Lord's Castle, which had remained unchanged for centuries, was about to undergo a massive transformation. The first being the Demon Lord had ever brought back of his own volition. She was a girl who would create new ripples throughout the demon realm.
