Pros so far (c438) :-

Awesome starting arc.

Great world building.

Side characters have their own individualities.

Pretty good fantasy power structure.

As the title suggests, majority is about MC's school-life, it is fun.

Humor is pretty good, sometimes even hysterical.

Cons so far (c438) :-

As one of the early reviewers mentioned that MC clearly suffers from guild tripping, sometimes it becomes to much and I just skip paragraphs by paragraphs.

From c430 or so (the lich tomb battle onwards), this novel goes to absolute sh!t, unlike the dog sh!t that you would clean because it is your pet's, no, it goes to the most horrendous sh!t. What I am referring to is that - it is quite clear that the author has a fetish about masochism, making MC the one of the biggest masochist. I meant that the novel transforms into a bait story, where MC will suffer from all sorts of indignation & will not utter a proper sentence to explain or just totally lose the mental capacity to put forward any logical sentence. For those who feel lost, I am pointing to the interrogation by Charlotte of MC. Not a single word, why? It's s*upid & exhausting that almost all good novels just lose their way halfway through the story, just like The Novel's Extra went to sh!t around c190.

I am still reading it, but sparingly now, unlike the previous binge I was on all my spare time. So, it will take some time & maybe effort to continue this. I am still on Vol 9, and there are 13 volumes, so who knows when I'd finish it.

Just a last note, recommending reading this, at least till c430 or c435. Also, author is a masochist & not in a good way.

Overall it's a story of a struggle young demon lord? trying to live as a normal magic school working hard good boy with no proposed and dream that believe the plot armor will always with him until he f*ck up sooner or later...

how Ellen integrated back to society, Reinhardt's shenanigans in Razeria, how each heroine seduced Reinhardt into making children, why Charlotte is the only love interest who doesn't have a child, heck I want to see Olivia's struggles in trying to raise her child.

there's a happy (?) harem ending including Ellen

Till the end, him being the author of the world bears no significance to the story and the origin of the system is still left unsolved. Where did the system came from? Who gave him the power and sent him there? Was there even an overarching purpose for him being sent there other than to fix his s*upid mistakes as an author? There are so many questions that should’ve been answered in the end that were just glossed over for some reason.

The epilogue also feels so lacking. There weren’t even any mentions on the status of the other empresses and if their friends in the royal class are still living well and whether they too have made their own family. Interactions between Reinhardt’s kids and the Royal class’ kids would’ve been nice to read but I guess we’ll skip that too. What about the promise Reinhardt made with Ellen’s mom? He completed it so why was there no reaction added from the mother in the end?

How can I start saying bad things about this? OK, first this world is a incomplete web novel with a lot of unexplaned things, and by that I mean both the world inside the novel AND the "outside" world, so the author can make anything really he can make anything, the imperial capital is actually Seoul but huh... "unmordenized but it still is modernized" the author couldn't build it on a good way but he gave a explanation through MC that can kinda explain but not that good so I won't say it's a good or bad point, I can only say is disliked it a lot

because it is a incomplete world and MC (AUTHOR) can come up with any bullsh*t like there's literally a skill that gives MC the way he needs to go, it's just poor writting, you know these movies/series/novels that come up with any bullsh*t to explain how the things happens? this is it, and it isn't good also there's another problem that I prefer to say it on spoilers about characters.

There's these races it's actually species but whatever I won't complain, Demons (which is actually a lot of species with different species skills and etc) and humans (that is the same as any random fantasy world they can have a lot of different powers and blah blah blah, really the author took my time to read things and just after he comes up with exceptions, I hate this guy)

Metamorph guy: forgot his name he really does exist, he is a fanatical about how arcdemons should be kings because they help all demon species to coexist he makes sense, he has good personality he keeps what he was made to do.

Werewolf girl: forgot her name and don't care either, she doesn't do much, she acts as a dog cuz MC old owner trained her to be this way, she's there she acts this way.

Vampire girl: forgot her name and I care even less about her, She's a Hypocrite she know that the ones who started the war was the human side and massacrated them for really no reason but still chooses the human side because... dunno she almost killed MC so that he can't be demon king but she knew that if MC dies all demons will lose control and fight each other and end up all dead even herself, shouldn't she like... help the demon side win so there's only demons alive? even I could think that... imagine someone that was made smart (by the plot) but not even tried to think? I know she hates the war but enough to sacrifice the entire demon population? she's actually worse than the metamorph that was said that he would kill everyone that MC loves so he can become king cuz he wants a king to command all demons so they won't end up dead.

Now the spoilers: Because MC can make things happens out of nowhere and even change how characters act any time it makes you think the world is "punishment game" ok, I get it, but... it's a novel... so we as the reader should only think of the characters as dolls being controlled by something... that's being a big plot hole you know... that's why all other novels with the same settings made so they got sent to a real world that the novel and characters are real and feel emotions... or even make the MC that is the author not even having a system to help them or tell them that what they wrote was actually only a reflection of the world they are right now or even just say they misundestood their past life with the new life so they thought they were in a novel but this author can't fix this hole not even if he tries it's not a real world but just game world with NPC so if MC ends up marrying any girl it's like he's marrying dolls.

There's none, the novel isn't really good, but I will keep try to read but really, this novel only 24 chapters made me feel how bad some writters can make their novel without even think about world, characters or anything that makes sense in a short time that feel like years (i felt it since chapter 2)
