Lucifer, the strongest Demon king has ruled the demon race with his overwhelming power.

Making a Harem with his dearest wife, he spent several hundred years eating, making love and sleeping.

Tired of sleeping, the Demon King began to seek for a powerful enemy.

Why doesn’t the hero come to subdue him? Even though he’s been waiting for so long.

Lucifer then turned himself into a human, and decided to go and see the military academy, which is a training institution for the heroes.

The best way to know what’s inside is to enroll in the school.

He quickly passed the entrance exam and enrolled safely…!?

This is a story of the most powerful demon king that becomes the strongest hero by mistake.

This concept is too good for this author.

The MC is incredibly unlikable and inconsistent, the girls are hollow, and the world is too generic to hold up the farce of a storyline.

Reading this was like consuming uncooked ground beef.

Two stars because it's not like consuming rotton uncooked ground beef.

This novel is pretty cliche, I've only read up to chapter 39, since the translation is hardly readable. It's a pretty mediocre novel, similar to those around it. I thought it might be interesting if it was something like Misfits of Demon Academy, however it's just another overpowered main character who turns into a pushover whenever a female is around him. (24/7)

Overall, it's a pretty decent read, don't get your hopes up for anything special though.

Pretty good story with pretty good translating. What happens when the demon king is so OP, that no one is willing to challenge him anymore?

Well, eventually, he gets bored with just having s*x with the wives he's broken after they tried to kill him. So, he goes to check out the opposition.

... more>>

Its cute how the wives are the ones who keep him from disguising himself as ugly, old, or female.

one of the few novels ive enjoyed lately, starts fairly normal, but as the story progresses, the main attraction of this becomes the characters and the mysteries (especially those) :

what happened that led to the destruction of the prehistoric civilisation, where is goddess ophelia and what is the holy flame, what happened to the beast god and his wife that led to the war happening now, what is the red glow in the sky that is always followed by disasters throughout history, and that supposedly the next time its red color is seen everything will end, and who was lucifer before he was named lucifer and who was lucifer 1, who is the unknown girl (godess?) who is moving everything and playing with everyone, what is her reason or purpose.... and a few other minor mysteries, an expanding world and writing that gets better in the second arc, and going from an op MC to actually having real threat looming on the story, and the way the author keeps giving you pieces of the mystery while sprinkling new ones here and there

i have far less gripes with this then I have positives, it was actually enjoyable, just wish the author didnt pause, and hope sales go high so that he goes back to writing and giving us some juicy explanations on the many questions he raised

One of my favorite novel, for now.

Came for dumb fun with good dose of ecchi but author trying to create a grand serious story with mysteriousness and all.

Issue is that you still get what you came for as in dumb fun with ecchi so both of them together don't really match well.

Still enjoyable but be warned that the story is kinda dark. And next thing you read MC is enjoying his wives.

An interesting premise. The MC is a demon lord who's bored by his daily life so he infiltrated the human academy which trains heros. But quickly things take a different turn as mysterious disappearances and other issues crop up which makes the MC question what's really happening. Well MC is a demon lord ngl. He's crass, cruel and hella op, he really behaves like a villainous demon lord. A fun popcorn read.

The story is good and the protagonist is even better. The protagonist's wives are all rational and the secondary characters have their own personality and "development"....
However, let me warn you that this is not a fighting novel, but a mystery, there is a whole drama behind it that has involved all the chapters so far, waiting for the next internationalization to see the result

Interesting plot. I cant say much more since they still havent finished translating Volume 1. But here is the breakdown of the story to from start till when I've read.

Basically a story of an overpowered Demon Lord named Lucifer who got bored since not a single soul have come to challenge him for a long time. He is tired of just cuddling with his wives and lazing about his throne.

One day he got an idea of going into human territory to take a look at the school that trains heroes.... more>> And here where he begins to interact with people from other races and probably accidentally got involved in a large conspiracy. I say probably cause they only mentioned a couple of things and still havent reached a point for that event.

Hope they continue translating this. If not, I'll just have to find the raws and read it myself. Became a bit good in reading machine jargon. A little bit. Good enough that I understand the story.

Ah yes. I forgot to mention a bit about Lucifer. He is so OP, that all heroes that came after him died without putting up any fight. One of em died when he just released a bit of killing intent and his head burst. The other died when Lucifer just "Hmph!" and the wind force I guess knocked him into a wall. <<less

This story starts off interesting, the Demon King joining a Hero academy is a fun idea. And as far as I can tell he isn’t a typical beta Japanese protagonist.

Interesting plot and concept. MC started interesting, but immediately became inconsistent and shallow. Setting is also inconsistent, if not for the interesting story I would immediately drop this, so instead will continue till I finish the first vol.

Translation for the ReadLNovel chapters is quite horrific.

If I were to take a guess I'd say it's pure MTL grade with no editing and it shows, genders are swapped about, there's very little continuity in naming with the other chapters and random short sentences that don't make much sense.

Apart from that unfortunate circumstance, the story is rather slow so only one major event has occurred with the climax of the event coming up in the recent chapters and is enjoyable enough before said MTL chapters.
