The final battle with the Demon King. Hero Sion had the Demon King cornered, but was betrayed by the four beautiful girls who were his companions, and they were all blown up with the Demon King.
However, saved by the Demon King, Sion miraculously survives and starts living in the Demon King’s country under the condition that his injuries heal! The Demon King’s name is Vila. Despite her lovely appearance, she struggles to lead the radical faction of demons who are eager to start a war with humans due to their strong power.
Sion, who sympathizes with Vila, his lifesaver, and her efforts to protect the demon tribe’s way of life and peace, cooperates in suppressing the radicals while concealing his hero identity.
The two gradually become attracted to each other and end up in a political marriage for certain reasons! Sometimes sweet, sometimes with a tense distance, their happy newlywed life begins… On the other hand, the four who betrayed Sion, initially praised as heroes who saved the world, gradually begin to reveal the crime of killing the hero…?!



This manga is funny, but at other times, the atmosphere becomes serious. It explicitly addresses World War II in Japan in a profound way during the climax. As someone from a country that was once colonized by Japan, I usually dislike this kind of plot... but objectively, this is truly great!
The art is good, and even though I initially disliked the anime's art style, the manga's visuals are impressive. I don't know why the manga is underrated, but it's definitely a must-read. It's funny, entertaining, emotional, and has a perfect formula for a sad-ending story. You might even enjoy buying the physical copy of this manga.
Thank you, Kobayashi-sensei, for creating such a fantastic manga!
