YOU DONT KNOW HOW MUCH I LOVE THIS NOVEL!
If you are here for epic fight, zero to hero development, hero gaining harem member left and right, finding party member to finally kill the demon king, getting OP cheat and weapon, then you wont find most of it here.
Also do note that this isn't a reincaration/isekai/going back in time kind of story, but a pure fantasy where the hero and the demon lord is person that is born and raised in that world, the world building also have that kinda background which is awesome, and the way the author deliver the story is also great, I love this novel so much, isekai story is nice because they have limitless potential and become awesome but you know how most of them goes, so this pure fantasy is a great breath of a fresh air especially since it was very well written, unlike 80% of jp wn recently.
Here light spoiler of the premise of the story (no important plot etc)
(btw if you have hard time getting into this novel since it start of kinda slow then try reading the manga, the anime isnt that great, quite the disappointment to be honest)
Spoiler
the Hero is strong, so strong that he could reach the demon lord alone, as he was about to kill "maou", maou asked, "yuusha, be mine!" of course he refused, and then an epic fight.... didnt happen, they start to talk about the world and unlike what hero initially thought, killing the demon lord won't solve anything, the demon lord knew that well and manage to persuade the kind but naive and not so bright hero, they end up becoming an accomplice, they fake their fight with mutual defeat to gain time.
Finally, the real journey began, they start their world revolution in human world, "how do you change the world? first you need to fix one main problem, food!" on country side somewhere they, or should I say the smart and talented Maou, start to spread some information on how to increase the crops yield and new kinds of crops, also other invention for the better of the masses, and even got title of "Saint" but of course its not all smooth sailing, while the demon king away the hero who is not so bright but strong as hell went to the demon world instead and take care of rebellion and other matter, while in human world the demon king busy with making deal with merchants and of course the nobles and religion would make trouble as usual just cuz they can, alright I admit that it's not the religion, it's the corrupt higher up, just like real world. Although this novel is full of politic, domestic affair, kingdom/World Building, there is also many fan service fluffy situation as a break, there is also light harem (not s*upid harem where the MC would get cute girl every single arc), and some touching scene as well which I absolutely wont spoil.
Although at the start it was kinda slow paced but they take their time building everything nicely, just so you could enjoy the development of the story and they will come nicely with some twist and turn, like drinking bitter coffee and eating a layered sweet and sour strawberry cream cake
Now that you understand the premise of the story I wont spoil the fun any longer, and everything just getting better from there so keep on reading!
