Alternate Titles: The end of the Showa era with me and the elf hero. Daily life, business. Plans for a slow dual world sales life? 僕とエルフな勇者さまとの昭和の終わり。日常、商い。スローな両世界販売ライフの予定？（改修版） Publisher: Kakuyomu, Syosetu Raws: https://kakuyomu.jp/works/16816700429279325015 Description: It is the end of the Showa Era(late 1980s). The main character, Kazuki Yamamoto, helps and protects women in a small rural shop. Surprisingly, that woman is a Hero from another world. Well, Kazuki, who doesn't know about it, helps the Hero back to his own apartment and takes care of her with all his might. The Hero's last memory is an encounter with the Demon King at Demon King's Castle. When she wakes up, her body is no longer wearing armor. She's naked. She immediately misunderstands that being nude equals to having being forcibly raped, on top of mistaking Kazuki, the main character, for the Demon King. Take responsibility! Thus begins the story of a stormy wife. So, is Kazuki himself a demon king in another world? Is he a reincarnator? Even he himself doesn't know how it ends. But he is someone who possesses enormous magical power. The former Hero(now a wife) decided to raise her husband to become the future Hero and Demon Lord. That's why it's not a different world harem, but a modern fantasy harem story. After that, it might be a good day for trading back and forth between another world and Japan, as is often the case. Why It Should Get Picked Up: Just the idea of a reverse Isekai elf in late 1980s Japan is interesting enough but it seems the author is adding many other story elements, like reincarnation, travel between worlds etc. This would be an interesting story to read.
