異世界から帰還したら地球もかなりファンタジーでした。あと、負けヒロインどもこっち見んな。

“I’m baaaaaaaaaack!!!” Six years ago, Yura Natsuki was summoned to another world as a hero. Drawn into the war between humans and demons, he was told the typical trope—to return to his world, he had to defeat the Demon King. He fought desperately, siding with the humans who ruthlessly cast aside even their own kind, used as a pawn, and forced into a horrific war—all because he desperately wanted to survive. He finally managed to return to Earth, only to encounter even more fantastical elements than another world—gods, angels, and aliens!? "Earth is pretty fantastical, huh?"
