The story is about a guy crazy about magic but because he's from out world there is no magic he then dies and is isekai'd into a world hoping for magic but is then told there is no magic. But then discovers there is magic so he starts to learn and study it. We then find out that the MC is born into a race called Rugure of seemingly half-humans half-demons that are adept at using magic and about a thousand years ago this race saved the world by defeating the demons and sealing them away. However, the humans feared them so they instantly turned on them and slaughtered all of them once the demons were defeated.

Whats confusing here is that the Rugure are the only one's with magic and able to fight off the demons and the MC is shown to easily make himself immune to any weapon a human might use but with no explanation the Rugure were simply slaughtered even though with the explanation given and shown they should easily be able to slaughter the humans.

When the MC first goes to the capital after having saved the kingdom from a demonic invasion the MC was first forcefully summoned, told he was given to the Queen but what is sort of hinted at being a goddess and being told that he would save the world. Then when he arrives in the capital he is "given" a noble title as a reward but also told that it's only a title in name and then ordered to do a bunch of stuff. Then while curing people he get's approached by nobles trying to force him to cure who they want but he refuses the guard captain + nobles then instantly tells him a bunch of BS about how he's nobody and refusing them / the Queen is punishable by death bla bla bla before trying to kill him on the spot.

Of course they fail and the MC knocks them out and then when he meets the Queen, the MC get's told that they were lying and abusing their positions and had no backings so now the nobles get's no punishments and the guard captain is suspended and might get demoted. Cause you know falsely using the Queens name and trying to mu*der the MC is worth a slap on the wrist at most. She also tells the MC how she's been using the MC and his name to the other stronger kingdoms/empires after which the MC just goes wow she's so awesome. Then the Queen tells him to work with her after which the MC is for some reason super impressed with her.

Since you know the Queen giving the MC 0 support, using him and forcing him to work for her 24/7 until he passes out, giving him no protection and giving the MC no rewards for everything he's done and is about to do is awesome according to the MC.

Rose practically dont exist on the WN, so dont expect anything from her, maybe is important in the LN, dunno.

And Marie.. The poor poor Marie, she taste the NTR sauce because Shion fall in love with another girl.. Welp she dont really care that much at the beginning.. But.. Poor girl.. All the Alabama county cry for your sadness.

In the latest chapters MC is literally abandoned by.. Well, everyone (except for the sister, family and some other characters.. Toretto was right.. Damn it), so even when he saved the world no one else really cared for him and was just another tool.. So its pretty heavy and infuriating, plus is even worst when the dumb Alabama sister start to accept the shitty reasons the pricks say to have to abandon Shion

Example 1: He apparently behaves in a friendly and helpful way towards his maid. In fact, however, he leaves her the work of at least 3-5 people. Without explanation, as a reader, you have to watch how this girl is exploited to the blood. And only much later does the reader learns in a subordinate clause that this behaviour of him as an employer is intended towards her! And instead of freeing her from these catastrophic circumstances at the end, he drives her unconsciously, or because he simply doesn't care, deeper and deeper into dependence. what an a**hole

Example 2: "I'm a virg*n and that's the only reason I can use magic." The protagonist comes up with this statement regularly, and any romantic subplot that is hinted at in the story is ultimately shattered because of this irrational and factually incorrect statement. It's hair-raising from the reader's perspective and downright ridiculously evil from the perspective of potential romantic partners. Any person who shows an interest in him is either held back permanently or hurt. In other words: The story is extremely disappointing and depressing in this aspect.
