This manga is another one of those mangas were the mc is reincarnated into another world and has to save the kingdom.
The story is pretty good long ago a white haired hero founded the king and the rulers were whites chosen by temple however a hereditary ruler came into power and because of that the 3 dragon clans declared independence the west invaded saying its to bring down a tyrant ruler..The tyrant died and now the allied forces losing their just cause for invading are occupying the capitol demanding reparations.This is a fantasy world where a year is equal to 48 months and the kingdom is made up of many races such as dragons beastman and other races.This leads to conflict as another country hates the white kingdom for its equally among races and believes in the supremacy of humans.
The art is pretty simplistic nothing too outstanding.
The mc was a guy who lost everything so now he tries to protect what he has.I mostly read this for the story.This manga is a harem manga this a fantasy world where the mc becomes ruler and its a medieval setting though there are tanks and cannons in this story but thats what the country that hates the white kingdom uses as they believe in human superiority so they don't use magic but their ingenuity.
This was a good read i read through the 25 chapters that are out in one sitting
If you want a good fantasy then you should check this out.If you hate harems then this is not for you though it doesn't focus on the harem that much.
