At the time of this writing, the princess has been sitting at her desk looking haggard for 50 chapters.

The cowardly hero who is given everything in the main character's stead steals from the castle treasury, awakens a great evil that nearly kills everyone in the castle, and wreaks havoc on two towns (presumably mu*dering many people), but ends up unpunished with a harem... you know... because it's funny and he's the comic foil.

Girl asks for adventurers to help bring her somewhere.

Once they get there. Girl turns from timid to a raging evil b***h "Haha, I was going to use you as a sacrifice, but now I'll just kill you"

MC pretty much does the equivalent of "Well I have this magic to stop that magic! Well then I'll use THIS magic to stop THAT magic too!" all without even thinking about it. It's literally that simple. I'm not dumbing it down.

Girl realizes she can't win and gives up "timidly".

MC lets her go, pretty much telling her not to do it (mu*der humans) again.

Girl says he's her master now.... the girl who is supposed to ONE OF THE FOUR DEMON "DIVAS"!! Just like that. Also, basing it off the description, I would bet they end up married within a few chapters.

Everything in the story seems to be leading up to him inadvertently saving the very country that banished him and tried to kill him (which being the nice guy he is doesn't seem to be a problem).

MC gets summoned by this corrupt King who has summoned something like 197 hero's before him, throwing them towards the 'Dark One' in an attempt to get them to solve his problems. The King upon realizing the Hero has no divine blessing and garbage stats sends the MC off rather forcefully to Delaveza Forest, which the Princess protests after hearing about it, as it's basically sending this guy to his death, given that this is a place the Demon army has been spotted recently.

This part, this build up period, I enjoyed (extending out to when he meets Fenrys, later Rys). The characters felt believable and even MC felt understandable. He was thrown into a tough situation and had to deal with it however he could. Next part, MC goes to the forest (a 20 day journey by carriage, with him imprisoned inside), at which point he's abandoned by the carriage only being given a bag of holding with money and necessities and some basic weapons in it.

MC takes a weapon out and kills some slimes that attack him after the carriage leaves, levelling up to 2. Upon levelling up he gains infinite stats and all skills, effectively. He's basically god. Now, we've been told that the MC was a child prodigy in mathematics, who grew up to be a successful business man. He was depicted as very talented at arithmetic. Here was the first fly in the ointment for me- MC doesn't recognise the infinity symbol (which all of his stats have become), at all. This is totally incongruous with his background, unless you accept that the medieval world they're from doesn't have such a concept, which... may be true, but I feel like that's more of a reach than to say the author couldn't be bothered to consider A to B here, and that is a running theme for the rest of the story.

MC soon discovers that his bag of holding, via passive warning skills, is enchanted to attract monsters towards him. He also gets the option to purify the forest and uses it. This levels him up over three hundred times at once. After that he decides he wants to go to town, and soon is given the option to teleport there, which he takes.

How does our genius MC react to all this? He promptly decides that it must be normal for people to learn teleportation at level 2 in this world, despite the fact that MC comes from a medieval fantasy world just like this one in which he knows only very high level sorcerers can do it. Moreover, he was just sent on a 20 DAY carriage ride by the King. If it were that easy to teleport someone why wouldn't they have done that? This is the first real example of MC being a completely brainless idiot - or rather, of the author pushing this angle of "MC is naive so he doesn't realise he's actually super strong compared to other people" - even though every logical indication in the world should tell him this. It's a classic case of forced writing, where the author had a direction in mind and tried to force it, not realizing that it's totally incongruent with the events taking place.

He also doesn't see anything unusual about levelling up over 300 times after casting one spell, deducing brilliantly that it must be a level-up "from casting a spell." And as for the bag, which all but confirms that the King maliciously planned his death? MC doesn't EVER spare a SINGLE extra thought about it throughout the entirety of the next 29 chapters. I'm serious, he never ever mentions it again, or ever feels any resentment, other than to reject the King's request later on (but politely, of course). Basically, he has no balls and no brains. Actually, it'd be fairer to say that he is simply not a real character at all, exhibiting no real signs of being a living breathing person. Rather our MC becomes more of a walking talking plot device that just solves problems instantaneously the moment they arise, only existing beyond the opening scenes to do this, and most of the story is not even about him.

Soon after, MC meets the main heroine, Rys. She poses as a little girl at the adventurer's guild in town and MC tries to help her. He is intercepted by a squad of four adventurers, who claim they don't believe he can teleport her and might be a trafficer. So he offers to teleport all of them to Delaveza Forest (where he just came from, and where Rys wants to go). He does this, shocking the adventurers and the little girl. But soon the little girl is revealed to be a ferocious demon wolf named Fenrys, the sister of one of the four legendary Demons in the Dark One's army. She threatens the knights and MC and intends to devour all of them with glee, and were it not for MC being busted power levels at this stage, she would have done exactly that.

However he teleports away the four adventurers and then he beats her in combat with an overpowered gravitation spell, at which point she... falls in love with him immediately, because he's so strong. That is the ENTIRE foundation of their relationship. The ONLY reason she likes him is because he's powerful. This is made especially clear later when she finds out MC killed her brother (and likely every other friend she had in the Demon army) in the purification spell he cast on the forest, and basically she says she doesn't blame MC at all and its her brothers fault for being a weakling. I cannot understate what an absolutely heartless monster Rys is, and how the author thought we could care about her is beyond me. I spent the entirety of Volume 1 futilely hoping she would have a miserable end, but it never comes. MC never once considers one iota of any situation he is a part of past the very opening scenes of the story.

Most of volume 1 is actually not even about the MC, because he is so busted in power level that every scene he's in becomes boring. So instead it's mostly about irrelevant side characters that he picks up along the way. I didn't hate all of those characters, but none of them are really significant. Neither is there any significance or stakes in anything the MC does, really. He has no ambitions or goals beyond 'living a simple life', doesn't have emotions like a normal person, doesn't feel vengeance, etc. The only positive I can give the protagonist is that at least he has a functioning libido, unlike most Jap protagonists written like this. But that's the issue, he feels exactly like one of those soulless ball-less herbivore protagonists in every other way.

As if just to deconstruct any further meaning behind the story, the author casually destroys not one, not two, but all three of the central antagonists of the story without MC ever even engaging them. I'm not kidding. The King who plotted his death casts a purification spell and falls unconscious for the rest of volume 1. The Golden Haired Hero who initially outshines MC at the beginning, turns out to be a coward with no potential and hides in a castle for most of Volume 1, eventually becoming despised without MC ever even being aware of him. And the Dark One, the central big bad of the story, becomes an enormous joke when he finds out about MC and starts visiting him, soon falling in love with Belirossa, one of the side characters (a weak human knight woman) that MC picks up and basically has as a pet at his house. This makes him come across as a love-sick clown instead of a Demon Lord, and is wholly incongruous with what we're initially told about the Demons, like Rys, who used to love butchering humans for fun (and she still would, if MC didn't dislike it).

The MC accidentally slaughters a demon general and his entire army, annihilating them from the face of the Earth. The general's sister tries to find human sacrifices to resurrect him. Since she was close to her brother, she probably had other friends or relatives killed by the MC. Even with all this hatred, she surrenders to him and decides to make him her "master." That night, she attacks the MC with lust spells, which he counters because he's just too OP. He then hits her with lust magic that is too much for her to handle and counter-rapes her. There is no way she could be in control of her senses enough to give consent. It's like raping a drunk person--you don't do it. Just because they're intoxicated and can't control themselves or express proper judgement doesn't mean they gave you the a-okay to bang them half to death.

After that, she continues to act like she's still under the effects of the spell. The MC is the most powerful person in the world, so his magic could definitely have long-lasting effects. She gives the vibe of a s*x s*ave more than anything else...

Aside from the battle, s*avery (he becomes her master), and r*pe, there really isn't anything else that makes their relationship happen. They don't discuss their different cultures, preferences, loyalties, families, values, etc. at all before they suddenly just get married.
