The Great Demon King of Time and Space

With an undying body, I brought the person I liked to my courtyard with a kind heart. I’ll share my immortality with them and let them enjoy eternal happiness.

That was all, but the Space Administration had labeled him as the ’Great Demon King who disrupted the order of space-time’, or’ Great Demon King of Space-time’. Not only did this name make me wanted by the entire universe, but the higher-ups of the Administrative Bureau also specially sent three magical girls who always fired randomly to hunt me down.
