Synopsis
Basically this Kazuhiro guy can travel between worlds when he sleeps, and he brings back a elf waifu with him one day. They go about their life making out and eating food.

This is by far one of the most boring novels I've read so far. Self insert fantasy isekai slice of life, with bland characters and a boring story. Have a read if you think this is worth your time.

Japan
Japan in this novel seems to be seen through the eyes of a middle schooler, who discovered Japan through kyary pamyu pamyu, or the local tourism board in Aomori. The author presents a beautified japan, so lovingly, it makes me wonder how much they are being paid off. The isekai world on the other hand is portrayed as "rough" and without the "culture" and "cuisine"that Japan has. It really goes to show when they visit anywhere in the isekai world that the author can't even be bothered to describe it at all. "wOw ThEse FRuIts TaStE sO BaD" like shut up I get it already, isekai world bad Japan good.
Most of this story is pretty much the author describing the meal they had at lunch, and is probably where all the effort went into. They cannot stop talking about food at all, guess author really wants to sell japanese food to foreigners.
Story
There is no story or plot, its a slice of life

Rant
The reason I straight up dropped this is

Spoiler, click to view

when they bring over the dark elf, who they were just fighting, who was apparently 'brainwashed' and had been interfering with them for about 2 volumes, she changes characters in the span of about half a page and loses all her animosity almost as fast as the author took to write her character.

The lack of care put into any of the characters really makes you think how low the standards of the japanese publishers must be to be able to pump out this garbage into bookstores. I'm convinced that the target audience is 7-12 years of age at this point because I don't think anyone with a halfway developed frontal cortex could be able to have a suspension of disbelief that could tolerate this garbage.
I have a suspicion that this author really dosen't know how to write a story, and instead wrote their daydream fantasies onto a word document and sent it over to their editor. This is really appaling considering the amount of paper that was wasted putting this book in print, and the wasted time of the translator who has to put up with trying to fix this mess of a novel.

This is really a rant and not a review at this point but I hope to deter any of you who would like to enjoy the little free time between work and school from picking this up. and to find something else to spend your time on, because this novel wasted a couple hours of my life and I hope some of you will have a better time than I did.
