Nihon e Youkoso Elf-san.
Welcome to Japan, Ms. Elf!

Edit

I'm just gonna straight into reviewing this after reading 5 chapters for the simple introduction if you found the manga by any chance.

This Manga is a fresh breathable air that I've been waiting for so damn long in Isekai plot. the last time I ever have this kind of feeling is when "Konosuba" and "The Black Healer" (Isekai de "Kuro no Iyashi Te" tte Yobarete Imasu) was out.

This one so far, took a route where the character is NOT "Reincarnated" or "Summoned" into another world like usual Isekai out there.

This one, is where the MC still alive and well. he goes to another world by ... sleeping, or you can say, "Dreaming". and he didn't want to live in that world either and still work like usual adults.

And well, you see by the name of the comic, The Elf got transported into HIS world aka Our Universe

and let just say, this kind of plot have some ORIGINAL potential to be a light of Isekai genre. let's do a quick review!

Story: 8/10

because it was original. I love every single original plot that blend so well. and this manga didn't copy the usual isekai manga as you can see.

Art: 10/10

The Author suuurrrreeeely have been making some other works before this. like seriously, the art is very beautiful. it can go from chibi into maturely detailed character that is so beautifully drawn like a popular slice of life manga.

Character: 7/10

Pretty good character. the MC is not dense and neither weak or strong. meanwhile the girl (the Elf) have some reasonable personality and not overaggressive like usual lead girl character.

Enjoyment: 9/10

It's very nice. it is light-hearted (so far after reading 5 chapters). probably recommended when you want to relax.

Overall: 9/10

Original, Did not have typical Dense or Overpowered MC, Very good art style, and enjoyable story plot.

I recommend it has a different plot than any other manga like you didn't die by truck-kun or just summon.Also, the mc isn't op like any other manga it has a few drawbacks or restrictions in its skill.

the art is top-notch and also fricking cute especially that elve girl. and the catgirl is different it's like a furry

the character design is pretty ordinary, but hey I don't mind it, it has a cute elve girl that does cute stuff and I can relate with the mc personality sooo yeahhh

overall I recommend this manga .if you had a bad day ... just read it, it only has 15 chapters so it won't waste much of your time

(sorry for the bad English I hope you guys could understand what I'm saying uwu)
