First I was drunk. Also that makes it weirder, it was basically father daughter sort of shit. Sure she's hot but he must have like no moral compass if he fucks her after seeing her nude. Especially because it wasn't like he was awake those 200 years, so even if it's a long time ago he has no other memories, so it is probably like being in a coma for a few years and seeing your family.
I don't know how to use spoiler tags cuz i usually shit post directly to the scan team in discord. But that's weird. Of course this is Japan, part of the reason why incest is so popular is the same reason step sibling porn is the rage online, people don't know what it is like having step siblings, so they assume having a hot horny step sibling is a blessing and could turn into a relationship. For the Japanese who have low birth rates, few have siblings, and the culture is exceptionally strict, where the last generation more or less doesn't talk to their spouses. Japan turned their warrior spirit into working spirit after getting bombed, where black companies are exceptionally common, working you for 100+ hours a week but paying you salary or only for 40 hours of work because finishing the project is their job, if they don't do it in a week they're fired, companies don't need to put extra members on teams or have joint projects because they can work individuals to the death for less than a grand a month. Sure people aren't fond of them but their work ethic is insane, regardless of when their shift ends it's policy to not leave until your boss leaves, even if they are sleeping at their desk. They have the highest rates of overwork deaths, so much so that being passed out at work is a good thing because it shows they worked so hard they collapsed, but if it happens often enough to disrupt their work they get fired.
Basically Japan loves incest and weird fetishes and puts that shit into comics because they don't often understand what sibling relationships or love are, they were raised without a lot of care most times, and even if they were top of class and athletics they only get acknowledged not complimented, they simply do what is required of them without too much emotion. It's why the most oppressed in history have the best art and imaginations, because only in their minds can they be free. It's why so many manga are op isekai because the teens love the idea of being surrounded by hot girls and having the power to end the world. Kids play pretend because it's more interesting than reality, Japanese love isekai because it's better than reality.
Also side note one reason they love using white people or dark skin gyarus is because their nation has much less diversity than USA. Having someone with pale white skin is considered traditional beauty which is why all those old paintings akways had them covered in white paint with red cheeks. I'm hungover right now so I dot't know if I'm ranting too much
Basically they love the ez life isekai because their own lives have like no freedom. Also the reason why they can write such dark and fucked up shit so easily. But my issue is this is just another manga following a popular trope and using a shit ton of cliches. If you Say isekai dude gets bitches that is legit every isekai manga, anime, etc. Isekai dude is OP is 99% of them, or at least the ones that get published. From there a shit ton are harem because horny boys love the idea of exotic women waiting on them, from which there's an obvious author favorite who gets all the screen time, but endings are often "he spends his whole life fucking unaware everyone wants to fuck him" (SAO [because the author admits he doesnt know how to write female characters who don't fall in love with the Mc despite him establishing a Canon ship] infinite Stratos where he is so fucking dumb he doesn't even understand when they show up almost nude to try to fuck him and he thinks it's an awkward joke and runs away, bridge to the starry skies where he doesn't know everyone wants to fuck him and then he ends up banging the main girl, Campione where he doesn't realize anyone other than the main chick likes him
From the harems using skyrim style romance, where doing a single task for a reward or because you felt like it, eg picking up books, sharing an umbrella, makes them possible waifus. Then there's the scum style where the dude rapes or fucks the women and they fall in love afterwards because they realize the dude is pretty nice to them, like the maou dungeon one, slavemancer classmate, etc. Then there's the women falling in love because they share a memory that the Mc has forgotten or doesn't recognize the other person, those are used to justify unrequited love.
Of these types of harems there are a few routes, the dude is either always oblivious or refuses to choose one because that would mean "hurting the feelings of the other girls who he also cares about" or because he doesn't know if he is ready to even try dating because he is afraid. There's the edge Lords who saw their crush fuck someone else and now hate romance but slowly open up to their harem ; half the time finding their first love again and reuniting only for harem to kick her out because she's actually scum trying to use the Mc or something. There's the ones that go out of their way to show the Mc winning each girls affection, only to have him choose the first girl because author doesn't know how to make twist endings or write realistic romance
Basically I'm drunk and this stuff is full of so many tropes and is done so wrong. I'm still gonna read it because it's trashy and entertaining, but I was drunk and pissed at all the tropes and boxed wine formatting
