The Undead King of the Palace of Darkness (WN) - Chapter 10: Malice

On a certain day, a certain thought came to Japan’s Sun Goddess. ——Aren’t there too many Japanese people being abducted to other worlds? It’s true that the large majority of Japanese are diligent and docile and soft-hearted, which makes them pretty much the best people to ask for favors. “But recently it’s just gotten way too out of hand…… Oh, I’ve got it! Whenever a Japanese person is summoned, I just have to summon an otherworlder!” And now, every time a Japanese person is summoned, princesses and elves and beastmen and whatnot are reverse-summoned. Under the acknowledgement of the government, they begin living in Japan. Today, too, Japan is at peace. And so begins this laidback isekai cultural exchange story♪

[ Late check-ins accepted. Abyss residues surcharges apply. ]The Last Neutral Inn, a small establishment run by a retired man named Aldous. He serves good soup, honest tea, and the only guaranteed neutral ground between the mortal world and the Abyss.He used to change the world. He doesn't do that anymore, but he has opinions about bread. He will share them.In a place where exiled gods need somewhere to sleep, demon courts require neutral venues for negotiations they can't afford to lose, and abyssal entities older than civilization occasionally need a simple word with someone who won't panic, Aldous runs the only establishment that qualifies. His guests aren't only human. His inn shouldn't exist. The Abyss stops exactly at his property line, which nobody has satisfactorily explained.Aldous makes soup. He fixes the stairs. He files the paperwork.He is no hero. No king. He runs an inn.The question nobody had the courage to ask yet is why.
