When I woke up after a thousand years, I realized that my compatriots were being treated as fodder by extraterrestrial demons. So I set out to slay the demons with my trusty battle companions: kitsune waifu, cutie alchemist, vampire princess, yin-yang master, sword-saint lady, hacker girl, cross-dressing bro, and cat-eared maid. But when I reached the Demon Queen, she told me that the Earth would be the dowry given to me for marrying her? Should I accept her offer and live an easy life, or should I lead the revolution to free Earth?
