Yuuya is a doormat with GOD level OP abilities, the guy just lets things happen to him. He's a YES man and never knows when to say NO and if he does say no, it's never firm. How is it a possibility that you can't be firm on saying No when you the MC can literally crush and obliterate anyone. Yuuya saying "NO" should put the fear of GOD in them (Since most of the characters knows about his capabilities). For a character who has god abilities the author always writes how he SUDDENLY WENT DEAF when a female character says something on the lines of "I want to date you/marry you/f*ck you."

Miku wrote such an over powered MC that he had to find dumb ways to make the story progress. Example, after a heavy battle, some how Yuuya needs to spend several days to rest and recover strength. Yuuya has a portable bath that literally instantly rejuvenates anyone using it, also he has his piggy familiar Akatsuki who's basic job is to use Sanctuary to heal and the little guy conveniently was not around to speed up Yuuya's recovery. OMG the f*cking "love interests" besides Kaori (she's forgiveableish), everyone is so annoying ESPECIALLY LEXIA the f*cking princess who keeps dragging the MC to do sh*t that he has no business doing. She's a constant glaring problem, every time Lexia wants to visit Yuuya, she's putting the lives of her personal guards in EXTREME DANGER, because of Yuuya's home base is in this DEATH FOREST. MIKU is so lazy at writing, he could have written a way for Lexia to contact Yuuya, but MIKU says NO?! It's more interesting that faceless side characters to risk their lives and die for the selfish princess' whims. How is Yuuya constantly having all these convenient things given to him, but in regards to Lexia he can't do a damn thing about her.

It becomes such an issue when Yuuya is literally becoming a weapon for the Isekai world and everyone is using him. f*ckING DOOR MAT!!! Also how is it that all the leading female characters instantly falls in love with this idiot who can't talk to them beyond one word responses and constant self doubting.

MIKU doesn't realize how big of an issue it is for him to write Yuuya's willy nilly granting people access to travel between worlds.

I should have f*cking dropped this LN on Volume 9 (but really I should have dropped it after the first chapter of volume one) the writing for Vol. 9 was extremely lazy and obnoxious, this is suppose to be a fantasy isekai but MIKU introduces a space battle with the MC INHERITING AND PILOTING A MECH. Also f*ck Merl and her Planet, the Dragonians should have wiped them out.

Update: 08/21/2023
I can't believe the author would bring Lexia in to Yuuya's world and attend school... He is so hell bent on making sure every female love interest is within arms reach for Yuuya. With the way he's writing this, I would not be surprise if he ends up writing how all the love interest is willing to share Yuuya amongst themselves. *facepalm* At this point of the story, practically every side character is planning to or is manipulating Yuuya to do whatever they need him to do. Even though the internal monologue clearly states he doesn't want to do it and right when he's about to say No, he'll always be like"well I'm nothing special, so I should f*cking put other's selfish needs before my own comfort and wants." Because this f*cking idiot doesn't know how to say No firmly. (f*ck you MIKU!!!) All the female characters lose all characteristics that differentiate themselves from one another, the only one that you can tell is different is Princess Lexia, because he wrote her to be a complete pain in the ass.

Obnoxious Adventures:
Yuuya travels to heaven to fix heavenly problems... *eye rolls* Gains heavenly powers from the journey.
Yuuya travels to the underworld to fix it's problems (granted it was Yuuya's unintentional fault from fixing heavenly problems). The author forgets that he wrote how Yuuya was brought to the undereworld to help patch the underworld barrier up with his new heavenly powers, and instead of using his new heavenly powers to do exactly what he was brought in to do, Yuuya was then asked to f*cking train with the spirits of The Sage, Bow Saint, and Yuuya's ancestor, to prepare to fight the Meiko, this sealed evil being in the underworld. How did the objective of patching the barrier turn into let's kill this demon. *facepalm*

You would think it can't get any more obnoxious than going in to space finding a Mech, then go to Heaven and fix God's problems, and lastly go to the underworld and kill the "ULTIMATE EVIL"

NO! MIKU has the audacity to f*cking bring in MULTIVERSE/parallel worlds because he's running out of ideas of problems to fix. f*ck YOU MIKU!!!

I don't have a problem with him writing about fantastical places that he wants to bring his characters to, but he barely spends time or even elaborate about the places. "Heaven/Upper Dimension" for example spends about 2 pages of writing imagery of a blank canvas, he's so lazy or lack the imagination, he writes Heaven is barren because everyone who has Heaven's Authority can build their own image of a place for themselves... LOL. When he writes about the underworld, he basically doesn't, he just brings Yuuya to it and meets the people who's going to help power him up, Yuuya solves the problem, brings the new girl home, the end. Reading the afterwords of the author in the volume makes this worse, becaue he literally tells us, he's been wanting to write about going to heaven and going to the underworld and then he pats himself on the back. I'm like "bit*h you barely wrote about it, you just had Yuuya gains some pointless powers to solve some dumbass problem."

This mother f*cker of an author forgot he gave the MC teleportation powers with NO f*ckING COOLDOWN to the ability. That can solve so many of the issues he written for Yuuya. smh

He goes to a town near the forest and suddenly remembers that he doesn't have money. And the first thought this s*upid guy has is to sell the stuff from other world. Not the loot he earned from the forest but the stuff from another world.

"Um, if you're going to go to the royal capital, why don't you use the rideshare carriage that regularly leaves from the rear gate?"

"Rideshare carriage?"

"Yes. It's a carriage that goes out to the royal capital at regular intervals, but if you're registered with the merchant's guild, you can ride it for cheap, and with this, you can definitely get to the royal capital without a map!"

At volume 8 the author introduced aliens from outer space to the story and also multiple universes with a massive powerhouse country or something, the story so far was basically getting to familiarise yourselve heavily with the isekai medieval world but then new water was splashed in which didn't suit for me so I've basically already dropped it because of this, if you like new alien sh*t in a story welcome to this novel but for me, I'm out!

Model girl is having an arranged marriage, and gets MC to fake up being her boyfriend. Her father, who is rich and president of some conglomerate, is the one who arranged the partner, and completely ignores his daughter's wishes of wanting to work in the entertainment industry. So when meeting with MC, he gets the partner he arranged to join in. This is said to be the owner of many companies including a casino. The guy tries to get on over MC and invites him to his casino to show the difference in their classes, and the super diamond dense level MC accepts it as trying to get the marriage canceled for model girl

Now, how to isekai stories usually show who is a better man? Of course, it's not through status, knowledge or experiences, but through fights or games, so instead of children's card games, MC wins through luck on all casino games he played. It's important to remember that Casino's don't play fair, and specially games like roulette are obviously are rigged. Thanks to MC winning, the guy gets flustered and shows his true colors, to model girl's father surprise, who never expected this guy, who owns a casino, mind you, to be someone who would do unfair business and even related to underground stuff. So the underground guy decided to send his goons to kill MC, showing nothing of the intelligence he should have to manage such business dealings. In the end, model girl's father apologizes to his daughter for not considering her feelings and stuff.

with the Other world resolved, now we get Aliens, so one alien (girl) drops buy, destroys half of his house, then a bunch of dragon aliens comes targeting her, they fight, there is turmoil, MC's house is almost gone, in despair he stops everything, the enemy retreats, the girl shoots her Wave Motion Gun from her arm, and then, with Earth now witnessing what was essentially an alien invasion, the girl triggers a device in her arm that erases the memories of everyone IN THE PLANET.

Oh, don't worry about internet, it also erases all stuff from the internet, cameras, and anything that could led to having to deal with such a plot twist. Now she joins the group, and explains that if he or his Genesis Dragon are revealed, she can erase the planet's memories, in fact, she just change clothes on the fly with technology in the open, not minding who is nearby, and just fixes everything with the technology. Oh, don't mind of side-effects, there are no side-effects, guaranteed by space alien technology.

Having to be able to bring a person of Earth, his first harem candidate, to another world. It was weirdly flat. The girl pretty much accepted everything as if it's normal af. Then it proceeded to a girl's talk in which the MC still as dense as a white dwarf star, doesn't realize any sh*t happening.

being trained to become stronger by the rabbit from Alice in the Wonderland.

Example, there's this girl who's trying to get revenge on the humans for killing her beloved master.
Some rabbit says, "Humans, did not plot to kill your master. They were only controlled by a mastermind."
The girl be like, "Understood, have a good day sir!"
